Hybopsis winchelli is a species of freshwater fish with terminal maxillary barbels at exist in various degrees of development. Some populations have well developed barbels while others have rudimentary barbels. Other populations have barbels that are nonexistent. Just as the barbel development is variable, so is the pigmentation of the fish.

The word "barbel" comes from the Middle Latin barbula, for "little beard." Barbels are sometimes erroneously referred to as barbs, which are found in bird feathers for flight. Barbels may be located in a variety of locations on the head of a fish. "Maxillary barbels" refers to barbels on either side of the mouth.
|
|
The mouth is inferior, the width from approximately one-half to two-thirds of the length of the head. In most species of Denticetopsis, the medial mental barbels are slightly shorter than the lateral mental barbels, with the latter approximately equal in length to the slender maxillary barbels. However, in C. sauli both pairs of mental barbels are approximately the same length and shorter than the maxillary barbels, and in C. royeroi all three pairs of barbels are approximately the same length. The dorsal fin is moderately large overall.
|
|
Barbels may also be nasal, extending from the nostrils. Also, barbels are often mandibular or mental, being located on the chin.
|
|
Arius species have three pairs of barbels, including the fleshy and cylindrical maxillary barbels and two pairs of mental barbels. The base of the adipose fin is moderately long, about half the length of the base of the anal fin.
|
|
The eyes are placed on the sides of the head and are visible from above, but not from below. The mouth is subterminal and its width is anywhere between 40-60% of the head length. They have three pairs of barbels, one pair of maxillary barbels and two pairs of mental barbels; the medial mental barbels are slightly shorter than the lateral mental barbels, which are in turn slightly shorter than the slender maxillary barbels. The anal fin is moderately long, beginning about halfway down the body, with the posterior- most anal fin rays with a slight, membranous attachment to the body.
|
|

Paraloricaria shows a strongly flattened body, weak postorbital notches, long and ramified maxillary barbels, and overall, conspicuous fringed barbels. Male Paraloricaria are abdomino-lip brooders.
|
|
The maxillary barbels are very short. The mandibular barbels are papillate. The gill openings are narrow. Paired fins are plaited to form an adhesive apparatus.
|
|
The dorsal fin is located far forward, close to the head, and is often high and triangular, thus inspiring the common name. The anal fin is somewhat lengthy, with 26-46 rays. Usually, they have two pairs of barbels, maxillary barbels and one pair of chin barbels, though adult Mekong giant catfish have only maxillary barbels. Pangasiids have compressed bodies and single small adipose fins.
|
|
Their common names - barbs and barbels - refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however. The large Barbus barbs are also often eaten in their native range.

When starved of food for two days under laboratory conditions, U. tragula develop large barbels compared to those developed by those who were fed consistently. The large barbels help the organism capture prey and compete against other individuals. However, individuals that developed large barbels also experienced a decreased growth rate. In the species Triportheus signatus, individuals have been found to develop barbels late in life as a response to low dissolved oxygen in pools left after flood waters recede following the rainy season.

Aguarunichthys was originally described due to the distinctive finger-like projections of the gas bladder. There are three pairs of barbels, one pair of long maxillary barbels and two pairs of shorter chin barbels. A. inpai has small spots on a cream-coloured body, while the other two species have large darker spots on an olive-brown body. A. torosus appears more elongate (it has a longer distance between its dorsal fin and adipose fin) and has a smaller eye than A. tocantinsensis.
|
|
Auchenipterus species have a number of pronounced sexually dimorphic features of the head, maxillary barbels, and anal fin.
|
|
Adults typically measure SL. They do not have rostral barbels but might have maxillary barbels. Juveniles have a colour pattern consisting of three black bars on body; this persists to adult stage in some species. Adults have a black, horizontally elongate blotch on the caudal peduncle .Found in western ghats.
|
|
The male possesses a genital papilla just before the anal fin, while the female does not. Also, in B. majusculus, B. obscurus, and B. vaillantii the nasal and maxillary barbels of males are more than twice as long as barbels of females; this may hold true for the whole genus.
|
|
Atopochilus species have their lips and barbels modified into a suckermouth. Atopochilus species range in size from in length.
|
|
Many long-whiskered catfishes grow to be very large, including the piraiba, Brachyplatystoma filamentosum, reaching about 3 m in length. They have three pairs of barbels, with maxillary barbels that may reach the length of the fish's body. Like many other catfishes, their bodies lack scales. The adipose fin is well developed.
|
|
In the lower jaw, the teeth are s-shaped and movable. The fish has one pair of long maxillary barbels, extending far beyond the operculum, and two pairs of mandibular barbels that are often branched. The adipose fin is small, 2 to 3 times as long as deep. The anal fin is pointed.
|
|
The eyes are small, dorsal, and located in the middle of the head. The barbels are annulated with black rings.
|
|
These fish have sensitive barbels and one should have the proper substrate for them. To keep their barbels (whiskers) in the best condition one requires the fine gravel that looks like coarse salt. This is available in white and brown, both look good. Beware that fry are difficult to spot on the brown gravel.

Austroglanis is the only genus in the catfish family Austroglanididae. This family was split off from the Bagridae catfish family. All three species of catfishes in the family Austroglanididae are endemic to southern Africa (South Africa and Namibia), and two species are threatened. These fish have three pairs of barbels (they lack nasal barbels).
|
|
The caudal fin is deeply forked. It has short, cone-shaped teeth in the upper jaw. In the lower jaw, the teeth are s-shaped and movable. The fish has one pair of long maxillary barbels, extending to about the middle of the pectoral spine, and two pairs of mandibular barbels that are often branched.
|
|
In the lower jaw, the teeth are s-shaped and movable. The fish has one pair of long maxillary barbels, extending far beyond the operculum, and two pairs of mandibular barbels that are often branched. The adipose fin is 3 to 3 1/2 times as long as it is deep. set far back.

Most distinctively, Linophryne (the most diverse genus) possess greatly elongated and highly complex hyoid (chin) barbels: these barbels are forked (with three to five main branches) and may be longer than the standard length of the fish, trailing below it in a tree-like manner. Sessile bioluminescent organs are also present on the branches of this barbel. The complexity and length of the hyoid barbel varies widely among species, with some having no forkings. In Haplophryne, barbels are absent altogether, and the illicium is reduced to a rounded flap.
|
|
Barbel roe is poisonous and causes vomiting and diarrhea in some people. However, the fish itself can be eaten and recipes are available in The Illustrated London Cookery Book by Frederick Bishop. The name barbel derived from the Latin barba, meaning beard, a reference to the two pairs of barbels—a longer pair pointing forwards and slightly down positioned—on the side of the mouth. Fish described as barbels by English-speaking people may not be known as barbels in their native country, although the root of the word may be similar.
|
|
Physopyxis have an extremely small size among doradids, not exceeding SL. Their pectoral fin spine reaches the base of the anal fin, and the dorsal fin spine is serrated only at the anterior margin of its base. There are three pairs of barbels, one pair of maxillary barbels and two pairs of mental barbels. The dorsal and pectoral fin spines are strongly ossified and well-developed. P. cristata can be differentiated from the other species by its incomplete lateral line and a series of small spines along its dorsal midline.
|
|
Key variations that differentiate this genus from all other families are the shape of the animal's skull, jaw muscles, and gas bladder — which fish use to rise and sink in water. The gas bladder has paired diverticulae, while other catfish families either have no diverticulae or singular diverticulae. Some external characteristics that may help distinguish this fish include nostrils set far apart, the presences of nasal barbels, maxillary barbels placed above the lip distantly from the corner of the mouth, and a rounded caudal fin. This fish has four pairs of barbels.
|
|
Rhynchodoras species are distinguished from all other doradids by their highly modified jaws which are strongly compressed, elongate, forceps-like in appearance, and project ventrally. The head is large and longer than it is wide, with a somewhat conical shape. There are three pairs of barbels, one pair of maxillary barbels and two pairs of mental barbels. Barbs occur on the dorsal fin and pectoral fin spines; on the anterior surface, barbs are curved towards the tip of the spine, and on the posterior surface are recurved away from the tip of the spine.

The Somalia catfish (Bagrus urostigma) is a species of catfish (order Siluriformes) in the family Bagridae. The Somalia catfish is native to the Jubba River in Somalia. This species has four pairs of barbels. The maxillary barbels reach to the middle of the adipose fin in juveniles and to the middle of the dorsal fin in the adult.
|
|
These catfishes have three pairs of barbels (nasal barbels are absent). The dorsal and pectoral spines are absent, or weakly developed (as in Leptoglanidinae and Trachyglanis). They reach at a maximum, but most species do not exceed in length. The small mouth is located on the underside of the head, and has thick lips bearing several soft lumps (papillae).

Dorsally, the head is gray to olive brown, but the upper jaw, tympanum, and sides are cream to yellow. Lower jaw, chin, and barbels are yellow.
|
|
Gravel with sharp edges will cut their barbels (until they are gone). Their barbels are important for finding food, and should remain healthy. These fish prefer a planted tank with temperatures around 60 to 75 ° Fahrenheit (20 – 24 ° Celsius) although they can take lower temperatures than this. Their high temperature tolerance seems poor and 30 °C (85 °F) is the highest safe temperature.

Several species of deep-sea fish have luminous organs used to attract prey. Females of the genus Linophryne bear barbels containing luminous organs in addition to an escal light organ attached to the head. In L. arborifera, the top light organ has been likened to a pearl onion and contains luminous bacteria. The barbels, which look like seaweed fronds, do not contain bacteria but complex paracrystalline photogenic granules.

This Asian arowana has large, protruding barbels In most vertebrates, the lips are relatively unimportant folds of tissue lying just outside the jaws. However, in mammals, they become much more prominent, being separated from the jaws by a deep cleft. They are also more mobile in mammals than in other groups, since it is only in this group that they have any attached muscles. In some teleost fish, the lips may be modified to carry sensitive barbels.

|
This fish can be distinguish from the otherwise similar starry sturgeon by the shape of its snout, its barbels and scale arrangement. The upper surface is greyish- green, the lateral scales are pale and the belly white.
|
|
In most fish species, barbels are used to aid in the acquisition of food in bodies of water that have low visibility due to low light conditions or murky waters. The taste receptors are able to detect enzymes in the water and help the fish identify if it is from a possible food source or possible sources of danger. The abyssal zone scavengers Coryphaenoides armatus possess one small mandible barbel that they use to search the seafloor for carrion to eat. Freckled Goatfish, Upeneus tragula, develop barbels as a response to food availability.

Danio dangila, the moustached danio, is a freshwater fish, and is the largest of the true Danio species at up to (6 in) long. Its name is from its particularly long barbels. It is sometimes kept in aquariums.
|
|
The barbels are usually white, but may have scattered pigmentation near their bases. Body colors can vary widely. The rays of the fins are dark. The standard length of the known specimen is and a total length of .
|
|
There are four pairs of barbels. The adipose fin base is not connected to the caudal fin. The caudal fin is emarginate with the upper lobe smaller than the lower lobe. The lateral line is midlateral and complete.
|
|
These goatfishes are usually solitary. They feed during the day on small fish and invertebrates, as gastropods, crabs, crustaceans (mainly crabs and shrimps), polychaetes and worms, foraminiferans, brittle stars and heart urchins, found by means of the two barbels.
|
|
Like other sturgeons, they eat mollusks and crustaceans which they find with their barbels. At the beginning of the 19th century, these fish were used extensively to produce caviar, but have been a protected species in Europe since 1982.
|
|
Their eyes are very small in comparison to the rest of the fish and they have three simple pairs of barbels. They have a deeply forked caudal fin, which also helps to distinguish this fish from other large Doradids.
|
|
Ameiurus catus has a head with eight barbels, two nasal, two maxillary and four chin. It is scaleless. It has a spine on the anterior edge of its dorsal and pectoral fins. It usually has six dorsal soft rays.
|
|
Diplomystids are the only extant catfish family with teeth on a well-developed maxilla (although this is also true of the extinct genus Hypsidoris). Diplomystids possess maxillary barbels. The dorsal and pectoral fins have spines. The largest species reaches .
|
|
These catfish lack scales, but their bodies are armored with a lateral row of bony plates. The head is large and flattened. The mouth is terminal (points straight forward). There are three pairs of barbels and the eyes are small.
|
|
This catfish is visually similar to the closely related Wels catfish. Soldatov's catfish has a large flat head. Its mouth is blunt and rounded, the upper jaw shorter than the lower jaw. Barbels are located on the upper jaw and chin.
|
|
It has two long barbels for locating food, which are as long again as the body in front of the anal fin. The dorsal fin is reduced to a tiny triangle, and the pectoral fins are longer than the head.
|
|
The Central American snapping turtle hunts by luring its prey with four to six barbels around the mouth. It is believed to be an omnivore that forages for an assortment of prey, including crabs, frogs, fish, shrimp, and plant material.
|
|
They gain melanophores on their head. Caudal and anal fins begin to develop and another pair of barbels appears near the nostrils. About 7 days after hatching, the larvae are 12 mm (0.5 in) long. All fins are nearly adult-like.
|
|
Ariid catfish have a deeply forked caudal fin. Usually, three pairs of barbels are present. They possess some bony plates on their heads and near their dorsal fins. At least some species have venomous spines in their dorsal and pectoral fins.
|
|
Ictalurid species have four pairs of barbels (commonly referred to as "whiskers" as applied to catfish). Their skin does not have any scales. The dorsal and pectoral fins usually possess a spine. The dorsal fin usually has six soft rays.
|
|
These colorful large catfishes have a brownish back, with yellow sides and characteristic orange- red dorsal fin and caudal fin (hence the common name). It has a pair of barbels on the upper jaw and two pairs on the lower jaw.
|
|
Concentrations of taste buds vary from species to species, with bullhead catfish having 25 buds in a square milometer of barbel skin. Barbels begin to develop during the embryonic, larval, or juvenile life stages of most of the species in which they are present. Development regulation of barbels has been linked to the C-C motif ligand 33 of the chemokine family of genes, due to its presence in barbeled catfish and zebrafish and absence or difference in expression in barbel-less members of the same families. This class of genes are signalling genes that provide migrating cells directional information during morphogenesis.
|
|
They have a large, depressed head with an expandable mouth. The eyes and teeth are small. They have dorsal and pectoral fin spines; P. fasciatum also has an additional, smaller, dorsal spinelet preceding the dorsal spine. They exhibit typical barbels of catfish, the maxillary barbels sometimes being quite long, especially in juveniles. P. fasciatum has 10-11 dark vertical bars that are relatively wider than other species of the Amazon, with fewer white vertical bars than dark ones; the pectoral fins and pelvic fins are darker with few or no spots; and the skull is at least one-sixth narrower than other species.

Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers".

|
|
Doradids are easily recognized by a well-developed nuchal shield in front of the dorsal fin, as well as well-developed bony lumps along the lateral line that form thorny scutes. Also, doradids typically have three pairs of barbels (no nasal barbels), an adipose fin, and four to six rays on the dorsal fin with a spine on the anterior (first) ray. These fish are sometimes called "talking catfish" because of their ability to produce sound by moving their pectoral spine or vibrating their swim bladder. Sizes range from SL in Physopyxis lyra to FL and in Oxydoras niger.
|
|
Schilbid catfishes usually have dorsal fins with a short base and a spine, but Parailia lack a dorsal fin altogether. Most species also possess an adipose fin. The base of the anal fin is very long. There are usually four pairs of barbels.
|
|
These fish have slender bodies, flat bony heads, notably flatter than in the genus Silurus, and broad, terminal mouths with four pairs of barbels. They also have large accessory breathing organs composed of modified gill arches. Also, only the pectoral fins have spines.
|
|
The lips are thick, fleshy and often papillate. The maxillary barbels have a well-developed membrane and a soft base. The gill openings are wide. The paired fins are plaited and modified to form an adhesive apparatus in some species of Glyptothorax.
|
|
Occasionally non-cyprinid fish are called barbels such as Austroglanis gilli, or Schilbe mystus, both are catfish. Some species of the genus Sinocyclocheilus a cave dwelling fish found in China have made use of the term barbel in their English common name.
|
|
The dorsal fin has 12 soft rays and has a deeply curved upper edge, and it has 31 - 32 vertebrae. The lips have rows of transverse ridges of tissue and they possess two pairs of well-developed barbels. They grow to 15 cm.
|
|
Adults are small, typically less than SL. Both rostral and maxillary barbels are present. Lateral line is complete and has 18–26 pored scales on body. There are one or two broad, black bars on flank, between bases of dorsal and anal fins.
|
|
Sawsharks have a pair of long barbels about halfway along the snout. They have two dorsal fins, but lack anal fins. Genus Pliotrema has six gill slits, and Pristiophorus the more usual five. The teeth of the saw typically alternate between large and small.
|
|
The tube-bearing scales of the lateral line are restricted to the first 6 or 7 scales anteriorly. The head is marked by numerous fine rows of pores, mostly in parallel groups on the snout, cheeks, interorbital space, and operuclar bones. Barbels are absent.
|
|
Parexocoetus mento is found in coastal waters close to the surface and it is rarely recorded in open sea. These fishes can jump out of the water and glide over the water. The eggs are covered in filaments and juveniles do not have any barbels.
|
|
Enlarged spines are located in the snout area and around the eyes, but not on the back. The eyes are on the top of the head with a strong concave surface between them. The outer nostrils are covered with short barbels. The spiracles are large.
|

|
|
Only Artedidraconids have chin barbels hanging from the lower jaw that drags through the sand and a hook shaped operculum. Otherwise, the operculum is rounded. Coloring ranges from light gray to dark gray with large spotting. Some species are tan or green or even red.
|
|
It grows to a length of 1170 mm, where male is about 65 cm and females is 75 cm. Head compressed and elongate. Barbels long, large and flattened. Dorsal surface light grey or brown with lighter below with no spots or stripes on body.

The outer pair of mandibular barbels extends just past the front of the pectoral girdle, about of the length of the head, and contains three to six weak branches, usually without secondary branches. The inner pair of mandibular barbels is about to as long as the outer pair, about of the length of the head, with three to five pairs of branches, with many secondary branches present. The skin of S. ilebrevis has a large number of tiny vertical skin folds. The exact purpose of the skin folds is not known, but is a characteristic of the species of Syndontis that are endemic to Lake Tanganyika.
|
|
Nangra is distinguished from all sisorids by having maxillary barbels that extend beyond the base of the pectoral fin (vs. extending no further than the pectoral-fin base), by having very long nasal barbels in which the barbel length is much greater than the eye diameter and often as long as the head (vs. length less than the eye diameter), and by having palatal teeth. Nangra species have a depressed head, dorsolateral eyes, an elongated snout, small conical teeth in the lower jaw, branchiostegal membranes free from the isthmus, no serrations on anterior margin of pectoral spine (but serrate posteriorly), and a well-developed maxillary barbel membrane.
|

Dentectus barbarmatus is the only species of the monotypic genus Dentectus, a genus of armored catfish. This species is endemic to Venezuela where it is found in the upper Orinoco drainage. There is very little ecological and behavioral information on this species. This species reaches SL. Although it has been placed within the Pseudohemiodon group based on its strongly depressed body, filamentous lips with long fringed barbels, and small, spoon- shaped and dentition, Dentectus also shows unique derived features such as the presence of plates along the outer margin of its maxillary barbels, and a unique mouth structure that distinguishes it from all other genera.
|
|
Dorsally, the head is covered with large distinct scales. There are two chin barbels. The neck is grayish brown dorsally, yellow ventrally, and has a few scattered blunt, conical tubercles on the dorsal surface. Limbs are gray on the outside, yellow beneath, and covered with large scales.
|
|
These barbels can be seen in the photograph of mouth of a Panaque shown here; they are the short pointed structures on either side of a suckermouth. This sucker-like mouth allows them to attach to rocks and remain stationary with very little expenditure of energy.
|
|
Brown bullheads are ectothermic, heterothermic, and bilaterally symmetrical. Brown bullheads can be distinguished from black and yellow bullheads by their yellow-black chin barbels, the missing bar at the base of the tail (which is present in black bullheads), and their 21–24 anal fin rays.
|
|
Barb captured in a fishing boat The head is rather large for the body, with no barbels. The giant barb ranks among the largest freshwater fish in the world, and is probably the largest fish in the family Cyprinidae.Nelson, Joseph S. (2006). Fishes of the World.
|
|
The barbels are white, and the fins have small black spots similar to those on the body. The maximum standard length of known specimens is with a total length of . Generally, females in the genus Synodontis tend to be slightly larger than males of the same age.
|
|
The Barbels were built with bow mounted diving planes, but these were replaced by sail planes (aka fairwater planes) within a few years. This feature was standard on US Navy submarines until bow planes returned with the improved , the first of which was launched in 1988.
|
|
The scaleless skin of P. nkunga is coated in mucus, and its mouth is surrounded by four pairs of sensory barbels. The spines of the serrated dorsal fin, which can lock into an erect position, are covered in toxic mucus that can be poisonous to humans.
|
|
Amphilius is a genus of catfishes of the family Amphiliidae. Amphilius catfish have fairly lengthened bodies, with short, depressed, and broad heads. They have three pairs of fringed barbels. The eyes, small and located dorsally, are very distant from each other, and are without a free edge.
|
|
Luciobarbus steindachneri is a species of cyprinid fish. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus.Crivelli (2006), de Graaf et al. (2007), Almodóvar et al.
|
|
Sinocyclocheilus donglanensis grows to standard length; mean length of five individuals was . The head is compressed and has developed eyes. The mouth has two barbels and is slightly inferior, with the upper jaw that protrudes slightly beyond the lower one. The body is compressed and completely scaled.
|
|
It contains 12 barbels: six on its snout and six on its chin. It has a pointed caudal fin (tail fin). Brotula barbata will sometimes have spots or freckles. It usually is brownish in color overall, with some individuals being closer to olive and others closer to red.
|
|
Odontodes on the head and trunk are otherwise of uniform size and distribution, and not arranged in conspicuous rows. The lips are roundish, wide and papillose. The maxillary barbels are short. E. limulus shares with E. pantherinus a single synapomorphy: the derived presence of seven branched pectoral fin rays.
|
|
This is a minnow with an elongated body and a flat, "wedge-shaped" head. It has a pointed snout with a large mouth and barbels. It has sickle-shaped pectoral fins and a forked tail fin with pointed lobes. It has taste buds in its anal and pelvic fins.
|
|
This catfish is generally between in length, though larger fish to 30 cm long are not uncommon. Fish of up to have been recorded from the Alligator River. Female fish are a little larger than male fish. The head is wide and mildly flattened with four pairs of barbels.
|
|
Mayor visit local fishfarm The climate in Kepahiang is suitable for breeding various kinds of land animals and fish. Species that are currently bred in Kepahiang are goldfish, tilapia, cichlids and barbels. Pisciculture is still operated on a small scale level by locals. Therefore, the potential remains largely untapped.
|
|
The anal fin—the fin found under the body of the fish—is long and has 21 to 27 rays, reaching the caudal—or tail—fin. The caudal fin is usually straight or barely rounded. Like other madtoms, black madtoms possess many chemically sensitive sensory pores and barbels.
|
|
The eyes are small, dorsolaterally located, and under the skin (subcutaneous). The maxillary barbels do not extending beyond the head. The dorsal fin spine is serrate anteriorly and smooth posteriorly. S. chennua, S. rheophilus, and S. torosus grow to about SL. S. rabdophorus attains a length of about SL.
|
|
When present, the adipose fin usually has a spine at the forward edge. These fish have, when they are present, a unique pair of maxillary barbels. These fish have relatively long intestines due to their usually herbivorous or detrivorous diets. The body is characteristically flattened in this family.
|
|
Unlike all other species, C. coecutiens has transverse, slit-like posterior nares rather than rounded posterior nares. The eye is completely absent in C. oliveirai; the eye, present to some degree in all other species of Cetopsis, is situated on the lateral surface of the head and is visible from above but not below. In most species, the mouth is inferior and the width is one-half the length of the head; the margin of the lower jaw is often gently to broadly rounded. The mental barbels are almost always approximately the same size and length to each other and often the same length as or sometimes shorter than the slender and short maxillary barbels.
|
|
Sarcoglanidines are all very small (to the extent of some species being considered 'miniaturized'), usually not exceeding 25 mm (1.0 in) in standard length (SL); Microcambeva ribeirae is the largest species, reaching 48 mm (1.9 in) SL. All except one species are poorly pigmented, with a translucent body in life. The three pairs of barbels present in other trichomycterids are also present in these fish, though nasal barbels tend to be reduced. In addition, some taxa have barbel-like structures on the ventral surface of their heads. Sarcoglanis simplex and Malacoglanis gelatinosus possess an uncommonly deep body, a hypertrophied sac-like adipose organ above the pectoral fin, and the absence of premaxillary teeth.
|
|
The wels catfish's mouth contains lines of numerous small teeth, two long barbels on the upper jaw and four shorter barbels on the lower jaw. It has a long anal fin that extends to the caudal fin, and a small sharp dorsal fin relatively far forward. The wels relies largely on hearing and smell for hunting prey (owing to its sensitive Weberian apparatus and chemoreceptors respectively), although like many other catfish, the species is characterised with a tapetum lucidum, providing its eyes with a degree of sensitivity at night, when the species is most active. With its sharp pectoral fins, it creates an eddy to disorient its victim, which the predator sucks into its mouth and swallows whole.
|
|
The outer pair of mandibular barbels extends just past the front of the pectoral girdle, about as long as head, and contains seven to eight, long branches, with short secondary branches present. The inner pair of mandibular barbels is about as long as the outer pair, about of the length of the head, with four to five pairs of branches, with secondary branches present. The skin of S. melanostictus lacks the tiny vertical skin folds that are found on most other species of Synodontis found in Lake Tanganyika. The exact purpose of the skin folds is not known, but it is typically a characteristic of the species of Syndontis that are endemic to Lake Tanganyika.
|
|
The sexual dimorphism is often pronounced and is expressed through the hypertrophy of odontodes on the pectoral fin rays, on the snout margin, and sometimes on the predorsal area of mature males. Certain genera also show sexual differences in lip and tooth structures. The Harttiini are characterized by numerous and pedunculated teeth, a caudal fin with more branched rays, the absence of postorbital notches and predorsal keels, a rounded mouth, papillose lips weakly or not fringed, and short maxillary barbels. The Loricariini are characterized by a more important variation in lips and teeth shape, the frequent presence of postorbital notches and predorsal keels, longer maxillary barbels, and less numerous teeth and branched rays in the caudal fin.
|
|
Brown bullheads are omnivorous benthic bottom feeders. Their diet consists of algae, mollusks, crustaceans, insects, crayfish and other smaller fish species. Brown bullheads are typically nocturnal feeders, but have been reported to feed diurnally. Bullheads have poor eyesight and are heavily reliant on their sensitive barbels to locate their food.
|
|
The first ray of the dorsal fin and the pectoral fins are hardened and serrated. It has three pairs of barbels, the two mandibular pairs are branched. The caudal fin is deeply forked with an extension on the top lobe. It has short, cone-shaped teeth in the upper jaw.
|
|
Most species have barbels on their chins, which they use while browsing on the sea floor. Gadids are carnivorous, feeding on smaller fish and crustaceans. Gadids are highly prolific, producing several million eggs at each spawning. This contributes to their high population numbers, which, in turn, makes commercial fishing relatively easy.
|
|
The body is compressed and becomes strongly compressed at the tail. The head is slightly depressed and the mouth is slightly inferior, with the upper jaw longer than the lower jaw. There is one pair of maxillary barbels and two mental. The dorsal and pectoral fin spines are strong and pungent.
|
|
There is a comb of small spines near the point of the operculum. The maxillary barbels have membranes, though these are not as wide as in Hemisynodontis. The caudal fin is forked, with each lobe ending in a point. Like other Synodontis species, this fish almost always swims upside down.
|
|
Adult P. lineatus search and stir the sand incessantly for crustaceans, mollusks, worms, and sometimes fish. P. nkunga feeds mainly on benthic invertebrates, using its barbels to feel around in the mud for crab and small fish. P. lineatus is an oviparous fish; this species has demersal eggs and planktonic larvae.
|
|
Luciobarbus guiraonis is a ray-finned fish species in the family Cyprinidae. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus.Crivelli (2006), de Graaf et al. (2007), Almodóvar et al.
|
|
Luciobarbus microcephalus is a ray-finned fish species in the family Cyprinidae. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus.Crivelli (2006), de Graaf et al. (2007), Almodóvar et al.
|
|
This is a medium fish, growing up to 50 cm, with a broad head and a blunt snout. The lips are fleshy, and lacking barbels. The body is deep and laterally compressed, with a distinctly humped back. The scales are large and cycloid in shape, with a complete lateral line.
|
|
The trout barb has an elongated, slender body which is laterally compressed with a sharp snout. The juvenile fish possess a pair of rudimentary maxillary barbels but these are absent in the adults. It has very small scales and has 85-95 scales along its lateral line. It has a forked tail.
|
|
The eyes are small and completely covered by skin. No barbels are present on the chin. On the upper edges of the gill covers are distinctive oval holes that open into pouch-like cavities. These pouches are present in only a few of the genera in the subfamily Amblyopinae (the eel gobies).
|
|
Devario is a genus of fish in the family Cyprinidae native to the rivers and streams of South and Southeast Asia. These fishes have short barbels and many species having vertical or horizontal stripes. These species consume various small, aquatic insects, crustaceans and worms, as well as, in the case of fry, plankton.
|
|
Juveniles greater than 57 mm in length are covered with pigment with the exception of the posterior and lower edges. No chin barbels are present in juveniles.Parin, N.V., and Shakhovskoy, I.B. (2000). A Review of the Flying Fish Genus Exocoetus (Exocoetidae) with Descriptions of Two New Species from the Southern Pacific Ocean.

|
The silver arowana (Osteoglossum bicirrhosum) is a South American freshwater bony fish of the family Osteoglossidae. Silver arowanas are sometimes kept in aquariums, but they are predatory and require a very large tank. The generic name Osteoglossum means "bone-tongued" and the specific name bicirrhosum means "two barbels" (from the Greek language).
|
|
Gagata species have a compressed head, eyes on side of the head, a depressed snout, small conical teeth in lower jaw, branchiostegal membranes broadly fused to isthmus, no serrations on anterior margin of pectoral spine but serrate posteriorly, no well-developed maxillary barbel membrane, outer and inner mental barbels close together with their origins nearly parallel in a transverse line, short nasal and maxillary barbels, and a lack of palatal teeth. Gagata species have a great range in lengths, from 5.8 centimetres (2.3 in) TL in G. sexualis and 7.6 cm (3.0 in) TL in G. itchkeea, to 15.0 cm (5.9 in) SL in G. cenia and 15.8 cm (6.2 in) SL in G. melanoptera, to 30.5 cm (12.0 in) TL in G. gagata.

Eventually, one male will succeed in courting a female, using his barbels to provide stimulation to the female, usually beginning with caresses of the female's caudal peduncle, followed by caresses of the fontanel and the front of the head. if the female is receptive, then the male positions himself before the female, so that the female's mouth is in close proximity with one of the male's pectoral fins. The male then clasps the female's barbels between the pectoral fin and the body, and this stimulates the female to press against the male's side. When seen from above, the fish form a 'T' shape when conjoined thus, hence the term 'T position' has become conventional in aquarium circles when describing the breeding of Corydoras catfishes.
|
|
The Malapteruridae are the only group of catfish with well-developed electrogenic organs; however, electroreceptive systems are widespread in catfishes. The electrogenic organ is derived from anterior body musculature and lines the body cavity. Electric catfish do not have dorsal fins or fin spines. They have three pairs of barbels (the nasal pair is absent).
|
|
Since the color pattern of the common sawshark may be more or less defined, the easiest way to separate this species from the common sawshark is the location of the barbels, which are closer to the mouth than the co-occurring common sawshark. Unlike the common sawshark, the southern sawshark likely feeds mainly on fishes.
|
|
Aquatic genets are thought to be solitary and crepuscular. They primarily feed on freshwater fish, including catfish, barbels, squeakers, carps, and also crustaceans. They possibly detect the movements of the fish with their whiskers, or attract the fish by patting the surface of the water with their whiskers. A pregnant female was collected in December.

Head of a European sea sturgeon The wedge-shaped head of the European sea sturgeon ends in a long point. There are many sensitive barbels on the facial area. The dorsal fins are located very far back on the body. Five longitudinal lines of large osseous plates are found on the body of the fish.
|
|
Moggel (Labeo umbratus) is a freshwater African fish in genus Labeo. It occurs within the drainage basin of the Orange River. The species has been recorded in the [Vaal], Olifants River in Mpumalanga and Limpopo, introduced there by anglers. This species is similar to L. capensis in colour and in its pronounced anterior barbels.
|
|
H. brachysoma has a large head and a wide mouth. The eyes are large and can be seen from below the fish. There is a dorsal fin with a hard spine as well as an adipose fin. There are four pairs of barbels, one nasal, one maxillary (sides of the mouth), and two mandibular (chin).
|
|
The first fossil of Eurypterus was found in 1818 by S. L. Mitchill, a fossil collector. It was recovered from the Bertie Formation of New York (near Westmoreland, Oneida County). Mitchill interpreted the appendages on the carapace as barbels arising from the mouth. He consequently identified the fossil as a catfish of the genus Silurus.
|
|
The back has distinct spots scattered on it, including on the dorsal and caudal fins. Unlike some other members of the family Sciaenidae, the spotted seatrout does not have any chin barbels. In stained water, this fish's background may take on a golden hue. Its shape and coloration is reminiscent of a brown trout.

The mandibular barbels have long, slender branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. xiphias, the spine is smooth in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.
|
|
The prominent lower jaw has two barbels at its tip. The gill rakers are stout. Asian arowanas bear teeth on many bones of the mouth, including the jaws, vomer, palatines, pterygoids, parasphenoid, and tongue. Asian arowana scales are large, cycloid, and, in some varieties, metallic- coloured, with a distinctive mosaic pattern of raised ribs.
|
|
Most of these fish have four pairs of barbels and a large adipose fin. The maximum size is 2 metres. In all fish except those of the subfamily Sisorinae, some sort of adhesive apparatus, either in the form of a thoracic adhesive apparatus or in plaited paired fins, allow the fish to adhere to objects.

Closeup of head of an adult Sternotherus minor The loggerhead musk turtle gets its common name from its unusually large head, compared to the common musk turtle (Sternotherus odoratus). Adults can be 8–13 cm (3–5 inches) in straight carapace length. Barbels are present on the chin only, not on the throat.Conant R (1975).
|
|
Their diet is mostly insect larvae, especially midge larvae. They detect their food with their sensory barbels, and their vision plays little part in their feeding behavior. Major competition for the speckled madtom comes from other species from the genus Noturus. The only known predators of the speckled madtom are the rock bass (Ambloplites rupestris) and larger Noturus species.

Rita is a genus of fish in the family Bagridae found in South Asia. These species have a single pair of mandibular barbels, an elongated Weberian apparatus firmly sutured to the basioccipital and the sensory canal on the posttemporal enclosed with bone.Ng, H.H. (2004): Rita macracanthus, a new riverine catfish (Teleostei: Bagridae) from South Asia. Zootaxa, 568: 1–12.

A. cataphractus is abundant in calm waters of swamps and mangroves. Omnivorous, they feed mainly on detritus; these fish search for food by digging in the sediment. They are of squat, tadpole-like shape, with a large, very ossified head that has three pairs of barbels, which are rather long. They are nocturnal animals active during twilight.
|
|
A continuous fin margin surrounds this tapering posterior half of the body. Their eyes are small. The eel-tail catfish has 4 pairs of barbels surrounding the mouth, and sharp serrated dorsal- and pectoral-fin spines which are venomous and can cause a very painful wound.Martin F. Gomon & Dianne J. Bray (2011) Freshwater Catfish, Tandanus tandanus.
|
|
Males are more or less colourless. Females possess strong sphenotic and preopercle spines and highly distensible stomachs. Males, other than lacking lures, barbels, and (in most species) jaw teeth, have larger olfactory organs and tubular eyes; short and stout denticular teeth are also present. Sexual dimorphism is extreme: females may reach a length of , while males remain under .
|
|
Exastilithoxus species are small, cylindrical loricariids. These species exhibit a round lower lip with fleshy barbels. Color pattern is generally mottled and dark brown with paler areas under and just posterior to the dorsal fin. The abdomen is white, fins are mottled, and the ventral surface of the caudal peduncle is colored as the sides, but slightly lighter.
|
|
The quillback is a large, ectothermic, deep-bodied fish found throughout North America. It has a small head, humped back and deeply forked caudal fin. The compressed body of the quillback makes it look flattened when viewed from the side. The quillback has a subterminal mouth with no barbels, and no nipple-like protrusions on the bottom lip.
|
|
While the ages of white croakers have not been determined conclusively, it is thought that some live as long as 15 or more years. Some spawn for the first time when they are between 2 and 3 years old. At this age they are only long and weigh less than . Also have barbels on the lower lip.
|
|
Danio is a genus of small freshwater fish in the family Cyprinidae found in South and Southeast Asia, commonly kept in aquaria. They are generally characterised by a pattern of horizontal stripes, rows of spots or vertical bars. Some species have two pairs of long barbels. Species of this genus consume various small aquatic insects, crustaceans and worms.
|
|
Synodontis membranaceus, known as the moustache catfish, is a species of upside-down catfish that is native to northern Africa. It was first described by French naturalist Geoffroy Saint-Hilaire in 1809 as Pimelodus membranaceus, from specimens obtained in the Nile River. The species name membranaceus refers to membranes present on the barbels of the fish.
|
|
Pseudobarbus is a ray-finned fish genus in the family Cyprinidae. The type species is Burchell's Redfin (P. burchelli). The scientific name is derived from the Ancient Greek pseudes ("false") and the Latin word barbus ("beard", in reference to the barbels of barbs). This genus contains some (and might contain all) of the South African redfins.
|
|
The Neosho madtom (Noturus placidus) is a small North American freshwater catfish. It has been listed as a near-threatened species in the United States since 1996. The Neosho madtom has features characteristic of all North American catfish, including scaleless skin and a relatively large head with sensory barbels. Adults average less than 3 in (8 cm) in length.
|
|
Akysis longifilis is a species of catfish belonging to the family Akysidae, the stream catfishes. It is only known to inhabit the Sittang River basin in southern Myanmar. As a small catfish, it is up to standard length, with a dark brown body marked with yellowish saddle-shaped markings, very long barbels, and a forked caudal fin.
|
|
The Iberian barbel (Luciobarbus comizo) is a ray-finned fish species in the family Cyprinidae. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus. This large barbel can grow to over long.Crivelli (2006), de Graaf et al.
|
|
Luciobarbus graellsii is a ray-finned fish species in the family Cyprinidae. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus. The Andalusian barbel was formerly included in L. bocagei as subspecies.de Graaf et al.
|
|
The Andalusian barbel or (Luciobarbus sclateri) is a freshwater fish species in the family Cyprinidae. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus. The Andalusian barbel was formerly included in L. bocagei as subspecies.de Graaf et al.
|
|
Malapterurus have an elongate and cylindrical body that gives them the general appearance of a sausage. The eyes are small, the lips are rather thick, and the snout is rounded with widely separated nostrils. The gill openings are narrow and restricted to the sides. Malapterurus species have three pairs of barbels, and lack a dorsal fin.
|
|
The species reaches a maximum length of up to and a weight of up to . A more typical size is and . It is considered one of the largest extant cyprinids (surpassed by the giant barb), and may live for up to at least 17 years. It has a large head, with a toothlees mouth surrounded by four barbels.

Kottelat (1996) Flying fox seen head-on Note lack of prominent lip-cushions or frills This genus feeds mainly on aufwuchs, detritus and small invertebrate and plant matter. Their mouthparts are not as apomorphic as that of many other Garrini; they do not have a pronounced rostral cap, but in addition to the two barbels on the rostrum they retain another pair of barbels at the rear edges of the lower maxilla. The upper lip carries a short bristly ridge, while the lower one has a sizeable hard edge with which they can scrape food off hard substrate like rocks or logs.Stiassny & Getahun (2007) Three species are frequent in the aquarium fish trade; E. munense is the only member of the genus that rarely (if ever) makes its way into the trade.
|
|
These sharks can live to be up to 9 years old. Like other sawsharks, the Short Nose lives a benthic lifestyle and feeds on benthic invertebrates. It uses its barbels to detect life on the ocean floor which it then paralyzes with its rostrum. The species is ovoviviparous and tends to give birth to a litter of 7–14 pups biannually.
|
|
Mullus auratus is a demersal species which is found over coastal mud or silty sand bottoms where it uses its barbels to find benthic invertebrates. This species is commoner in offshore oceanic, continental shelf waters than it is in coastal habitats. It is normally found between over a sand-mud substrate. The larvae and juveniles are associated with Sargassum weed.
|
|
They also have prominent barbels on the lip. Some goldfish varieties, such as the common goldfish, comet goldfish, and shubunkin, have body shapes and coloration that are similar to koi, and can be difficult to tell apart from koi when immature. Goldfish and koi can interbreed; however, as they were developed from different species of carp, their offspring are sterile.
|
|
Like other angel sharks, S. caillieti has a flattened, ray-like form with greatly enlarged pectoral and pelvic fins. The horizontal edges of the broad, rounded head bear enlarged folds of skin. The large nostrils are teardrop-shaped and preceded by flaps of skin enlarged into two cylindrical barbels that overhang the mouth. The eyes are horizontally oval and placed relatively close together.
|
|
Pimelodus pictus, like other members of the Pimelodidae, are known for having extremely long barbels. These can extend all the way to the caudal fin. The fish are silver-colored with black spots and stripes. They have sharp spines on their dorsal and pectoral fins, which makes shipping a difficult task, since the spines can pierce plastic bags and get caught in nets.
|
|
Also present on the lower jaw are two fleshy barbels, chemosensory organs which help the nurse sharks find prey hidden in the sediments. Behind each eye is a very small, circular opening called a spiracle, part of the shark's respiratory system. The serrated teeth are fan- shaped and independent; like other sharks, the teeth are continually replaced throughout the animal's life.
|
|
Toadfish are usually scaleless, with eyes set high on large heads. Their mouths are also large, with both a maxilla and premaxilla, and often decorated with barbels and skin flaps. They are generally drab in colour, although those living on coral reefs may have brighter patterns. They range in size from length in Thlassophryne megalops, to in the Pacuma toadfish.
|
|
The quillback (Carpiodes cyprinus), also known as the quillback carpsucker, is a type of freshwater fish of the sucker family widely distributed throughout North America. It is deeper-bodied than most suckers, leading to a carplike appearance. It can be distinguished from carp by the lack of barbels around the mouth. The quillback is long-lived, with age beyond 50 years documented.
|
|
The most common arrangement is one or two rows of photophores on the ventral aspect of the body. The rows run from the head down to the tip of the tail. Photophores are also present in chin barbels of the family Stomiidae. The light produced in these glandular organs is the product of an enzymatic reaction, a catylization of coelenterazine by calcium ions.
|
|
They are omnivorous, so eat almost anything, from grains and other plant matter to insects, dead or living fish, and crustaceans. They have short, pointed, conical teeth, formed in multiple rows called cardiform teeth. Black bullheads have no scales; instead, they have about 100,000 taste receptors placed all over their bodies. Many of these are located on the barbels near their mouths.
|
|
Females are also typically larger than males. The head is vaguely triangular in shape, with a pointed snout and sharp beak, and yellow-green striping from the tip of the nose to the neck. Barbels are present on the chin and the throat. The plastron is relatively small, offering little protection for the legs, and has only one transverse, anterior hinge.
|
|
R. macrops reaches a length of SL. It shares features with representatives of different groups within Loricariini. For example, it possesses conspicuous fringed barbels on the lower lip, a feature shared by the representatives of the Pseudohemiodon group. It also bears numerous papillae on the inner surfaces of the lips and numerous straight bicuspid teeth that are characteristic of the Rineloricaria group.
|
|
These buds are especially concentrated on the fish's four pair of barbels (whiskers) surrounding the mouth — about 25 buds per square millimeter. This combination of exceptional senses of taste and smell allows the channel catfish to find food in dark, stained, or muddy water with relative ease. They also possess a Weberian apparatus, which amplifies sound waves that would otherwise not be perceivable.
|
|
The woundfin is a small slender, silvery minnow, with a flattened head and belly, long snout, leathery skin, and no scales. There are barbels on the corners of its lips, and its common name likely comes from the first spinous ray of its dorsal fin, which is sharp-pointed. Its maximum length is rarely more than 7.5 cm (3 in)."Plagopterus argentissimus".
|
|
C. pacifici reaches about SL. These fish have small eyes, wide mouths, and three pairs of barbels. These fish have serrae on their dorsal and pectoral fin spines. Dorsal region of the head, lateral surface of body, and adipose fin are brown, and the ventral region cream (beige) with some brown spots. There are four dark brown vertical marks on sides.
|
|
This is a transparent freshwater catfish with two long barbels. Standard lengths may range up to , but usually only reach around in total length. They are transparent because, like all catfish, they are scaleless, and catfish within the genus Kryptopterus lack body pigment. Most of their organs are located near the head; with a magnifying glass, their heart can be seen beating.
|
|
Its meristic data are that there are three-four dorsal fin spines and 7 rays while the nail fin has three spines and five rays and the lateral line has 37-40 small scales. It has a single pair of barbels and the males develop drak red fins and tubercules on the head when breeding. It grows to around 12 cm total length.
|
|
These catfishes have wide mouths, small eyes, and short barbels. Their bold markings lead them to be commonly known as bumblebee catfishes or dwarf marbled catfishes. B. acanthochiroides grows to 80.0 cm (31 in) TL. However, most species are smaller; species of the genus Microglanis rarely exceed 70 mm(2.8 in) SL and are never over 80 mm (3.1 in) SL.
|
|
Osteogeneiosus militaris, the soldier catfish, is a species of sea catfish found in the Indian and western Pacific Oceans from Pakistan to the Malay Archipelago. It is found in marine, brackish and fresh waters along the coasts. It grows to a length of 35 cm and is commercially caught for human consumption. It has a single pair stiff, sharp, maxillary barbels.
|
|
Upeneichthys vlamingii occurs in bays, estuaries and sheltered coastal waters, normally where there are sandy and rubble bottoms near reefs in depths of . The juveniles frequently form schools in sheltered bays. Like other goatfishes this species uses its barbels to search I the substrate for prey, which for U vlamingii is mainly crustaceans but also somepolychaete worms and a few small fish.
|
|
The Parascylliidae, or collared carpet sharks, are a family of sharks only found in shallow waters of the western Pacific. They are relatively small sharks, with the largest species reaching no more than 91 cm (3.0 ft) in adult length. They have elongated, slender bodies, cat-like eyes, and barbels behind their chins. They feed on small fish and invertebrates.
|
|
The Hemiscylliidae are a family of sharks in the order Orectolobiformes, commonly known as longtail carpet sharks and sometimes as bamboo sharks. They are found in shallow waters of the tropical Indo-Pacific. They are relatively small sharks, with the largest species reaching no more than in adult body length. They have elongated, cylindrical bodies, with short barbels and large spiracles.
|
|
These sharks typically feed on small fish, squid, and crustaceans, depending on species. The function of the sawshark barbels are not well understood, and neither is how they use their rostrum. It is possible they use it in a similar fashion as sawfishes, and hit prey with side-to-side swipes of the saw, crippling them. The saw could also be utilized against other predators in defense.
|
|
They can also be found in the eastern portion of the Indian Ocean. The longnose sawshark prefers to swim in both the open sea and coastal regions from the surface to a depth of 600m. The longnose Sawshark is known to mainly prey on small crustaceans. It uses its barbels to detect prey on the ocean floor which it then hits with its snout to immobilize it.
|
|
Another characteristic typical of the armoured catfish family is an iris. Most fish are unable to regulate the amount of light that enters the eye since they have irises that cannot change size. Both male and female Panaque develop bristles, known as odontodes, on the side of head immediately before and onto the pectoral fins. Unlike predatory catfish, these omnivorous catfish have very short barbels.
|
|
Brindled madtoms are approximately long. The brindled madtom, like other Noturus species, has a caudally-fused adipose fin which extends from the caudal fin and runs nearly to the dorsal fin. The caudal fin spreads around the caudal peduncle, terminating just prior to the anal fin. The species has smooth skin without scales and possesses four pairs of barbels along the premaxilla and dentary.
|
|
The armored searobins, or armored gurnards are a family, Peristediidae, of scorpaeniform fishes found in deep waters around the world, with most species in tropical regions. They are related to the searobins in the family Triglidae, and some authorities classify them in that family, but they are encased in heavy scales with prominent spines. They have prominent and often elaborate barbels on their chins.
|
|
The Atlantic hagfish may grow up to long, with no eyes and no jaws; its star-shaped mouth is surrounded by 6 barbels. There is a single gill slit on each side of the eel-like body. It has a total of 88–102 pores from which it can exude a slimy mucus. Hagfish have very flexible bodies which allow them to manipulate themselves into knots.
|
|
Koi have prominent barbels on the lip that are not visible in goldfish. Goldfish (金魚) were developed in China more than a thousand years ago by selectively breeding Prussian carp for color mutations. By the Song dynasty (960–1279), yellow, orange, white, and red-and-white colorations had been developed. Goldfish (Carassius auratus) and Prussian carp (Carassius gibelio) are now considered different species.
|
|
The fourbeard rockling is a long, slender fish named for its four barbels, one of which is on the chin and the others on the snout. The vent is halfway along the body and behind that, the body is laterally compressed. The anterior dorsal fin has one prominent long ray and is otherwise short and low. The posterior dorsal fin is very long and of even height.
|
|
The skin is tough and smooth. Body coloration in adults vary from olive-green to brown, black or purplish on their backs and white on the underside. A downturned mouth with fleshy lips surrounded by a number of barbels assist them with feeding. They are a solid, almost cylindrical, elongate fish, with the posterior half of their body tapering into a pointed eel-like tail.

Atema, Jelle (1980) "Chemical senses, chemical signals, and feeding behavior in fishes" pp. 57–101. In: Bardach, JE Fish behavior and its use in the capture and culture of fishes', The WorldFish Center, . Because their barbels and chemoreception are more important in detecting food, the eyes on catfish are generally small. Like other ostariophysans, they are characterized by the presence of a Weberian apparatus.
|
|
Danionella species lack scales and barbels, but possess a lateral line. D. mirifica has a single row of melanophores between the pelvic fins and the tips of the cleithra, and there is a lack of melanophores on the underside of the abdomen. D. dracula reaches 17 mm in length. It is neotonous, lacking 44 bones that develop late in the related zebrafish Danio rerio.
|
|
M. beninensis is a fleshy, robust fish that grows to a maximum length of . It has a fusiform body (tapered at both ends) with a large head and a thick caudal peduncle. The eyes are small and slit-like, and the jaws are either of equal length, or the lower jaw is slightly longer than the upper. There are three pairs of sensory barbels around the mouth.
|
|
The Siamese algae-eater has a black horizontal stripe extending from opercle to tail. The stripe can fade to camouflage the fish against its surroundings. Genuine Crossocheilus siamensis, without maxillary barbels and with deeply fringed V-shaped upper lip are rarely encountered in the aquarium trade. Closely related is the red algae-eater Crossocheilus langei, a species that is widely sold as the Siamese algae-eater.
|
|
The outer pair of mandibular barbels is a little under twice the length of the inner pair. They have short branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. pardalis, the spine of the dorsal fin is about as long as the head, slightly curved, smooth in the front and serrated on the back.

In S. guttatus, the spine of the dorsal fin is about the length of the head, smooth in the front and serrated on the back.
|
|
Goatfishes are benthic feeders, using a pair of long chemosensory barbels ("whiskers") protruding from their chins to feel through the sediments in search of prey. They feed on worms, crustaceans, molluscs and other small invertebrates. Other fish shadow the active goatfish, waiting patiently for any overlooked prey. For example, in Indonesia large schools of the goldsaddle goatfish (Parupeneus cyclostomus) and moray eels hunt together.
|
|
The young or hatchlings typically resemble parents except for brighter coloration. Twist- necked hatchlings measure around 4–6 cm in carapace length and about 20 g or 0.04 lbs. Mating typically occurs during the rainy season of the Amazon rainforest (late March to early December). Males follow females, mount from behind, then proceed to rub their chin barbels (fleshy filament) against the top of females’ heads.
|
|
Ideally Corydoras sterbai should be housed with a fine substrate such as sand or gravel in order to avoid doing damage to their delicate barbels. However, large gravel will suffice as long as it is not sharp edged. Their only other requirement is that shade be provided for them, by means of overhanging rock, large leaved plants, arching bogwood or caves. Breeding is not too difficult.
|
|
Rhamdia zongolicensis grows to at least about standard length. It is related to the surface-dwelling Rhamdia laticauda, considered to be its sister species. Because the surface species is nocturnal, and thereby adapted to darkness, the cave species shows only few new adaptations: elongated barbels and extreme ability to withstand starvation (at least seven months under experimental conditions). It also shows reduced pigmentation and smaller eyes.
|
|
They also listed it as one of the "best flying type Pokémon", describing it as a "flying sea snake." Author Ash Dekirk wrote that Gyarados and Magikarp were inspired by the Asiatic myth of the Dragon Gate. He adds that it is "scaled in sapphire" with "catfish barbels" on its "somewhat blunted snout". Author Loredane Lipperini similarly described Gyarados as resembling something from the Chinese New Year.
|
|
Carpet sharks are sharks classified in the order Orectolobiformes. Sometimes the common name "carpet shark" (named so because many species resemble ornately patterned carpets) is used interchangeably with "wobbegong", which is the common name of sharks in the family Orectolobidae. Carpet sharks have five gill slits, two spineless dorsal fins, and a small mouth that does not extend past the eyes. Many species have barbels.
|
|
Many species of Pimelodidae have juvenile forms that appear differently from their adult forms in color pattern, as well as body shape. Brachyplatystoma species have specialized pelagic young with greatly elongated barbels and fin filaments, and strongly ornamented pectoral spines. Other large pimelodids, such as Pseudoplatystoma, Sorubim, and Sorubimichthys, whose young inhabit vegetated, marginal waters, have distinctive cryptic coloration patterns and much enlarged caudal and pectoral fins.
|
|
It has an iridescent look. The female fish has two pairs of barbels. In the wild, the pearl danio is found in along the surface of small, clear rivers and hill streams. They live in a tropical climate with water with a 6.0 – 8.0 pH, a water hardness of up to 5 – 19 dGH, and a temperature range of 68–77 °F (20–25 °C).
|
|
The species can be distinguished from the related P. skeltoni, P. burchelli, and P. burgi by two pairs of barbels around the mouth. Upon dissection, it can also be distinguished by the length of its intestine, which is longer (relative to body length) than any other species of Pseudobarbus. Individuals of Pseudobarbus verloreni grow long. The species has large eyes and a compressed snout.
|
|
Lithoxus contains some of the most dorsoventrally flattened fishes in the world. They can be distinguished from most loricariids by having a round instead of oval lower lip. The lower lip is large and round as in Exastilithoxus with the edge sometimes frilled, but not with the barbels seen in Exastilithoxus. Lithoxus species have a unique, enlarged, thin-walled stomach from which the intestine exits dorsally.
|
|
Atractoscion is a genus of fish in the family Sciaenidae found in the Atlantic, Indian and Pacific Ocean. The genus is distinguished by having a lower jaw that protrudes beyond the upper jaw, shape and position of the swim bladder, the lack of barbels and sensory pores on the chin, teeth that are cardiform or pluriserial, and caudal fin that is slightly emarginate to lunate.
|
|
Tandanus tropicanus or the Wet Tropics Tandan is a species of eeltail catfish native to Australia. It was discovered in rivers between Townsville and Cairns by a group of scientists from James Cook University. The species, which grows to length of about 20 inches, has a cylindrical body tapering to a thin, eel- like tail. It has small eyes and a large mouth surrounded with barbels.
|
|
In order to feel, it has maxillary barbels. These are whisker like appendages that serve as tactile organs near its mouth. Thus, these whiskers allow it to better feel its surroundings. For movement, it has a dorsal fin with one spine and nine branched rays and five branched anal rays. Its maximum total length is approximately 165 cm and its maximum weight is approximately 70 kg.
|
|
Garra geba has a total of 11 dorsal soft rays and 9 anal soft rays. Garra geba have distinct features in which it is distinguished from African congeners. Their depressed head and gracile body, between five and nine predorsal scales, asquamate chest, posterior chamber of gas bladder small all contribute to individual features. It is a very slender and elongated fish with two pairs of barbels.
|
|
The Siamese algae eater has a black horizontal stripe extending from opercle to tail. The stripe can fade to camouflage the Siamese algae eater against its surroundings. Genuine Crossocheilus siamensis, (incorrect species) without maxillary barbels and with deeply fringed V-shaped upper lip are rarely encountered in the aquarium trade. The red algae eater is a species that is widely sold as "Siamese algae eater".
|
|
The caudal fin is forked and the fish has two pairs of barbels. Enteromius baudoni are benthopelagic, potamodromous fish that are harvested for human consumption. Threats to the species include deforestation, which leads to additions of silt in their ecosystem. The species was evaluated in 2009, and found to be of Least Concern by the International Union for Conservation of Nature and Natural Resources.
|
|
The barbels on its chin are roughly the same length as its head. The colour of this species is very variable with a background colour which may be greyish- cream, pale greenish, pinkish to orange-red. Many specimens show a reddish or black stripe along the flanks from the snout to the caudal peduncle. The adults have the scales on their bodies marked with blue spots.
|
|
It has six to ten dermal lobes behind and in front of its eye and a tubercle above its eye. Its body lacks ridges or caudal keels. Other characteristics of the species include dermal flaps surrounding the rim of its mouth, large barbels extending from its nostrils, and large spiracles. Like other sharks, the spotted wobbegong has abundant pores that operate as electroreceptors in its skin.
|
|
The Brazilian snake-necked turtle is a small species reaching a straight carapace length of between with a weight of . The carapace of the adult is oval in shape varying in color from dark gray, through to dark or light brown. The plastron is a yellow or cream color. The species has a moderate-sized head with a small snout and yellowish jaws, with no barbels on the chin.
|
|
The dadio (Laubuka dadiburjori) is a cyprinid fish, is rarely seen in the aquarist hobby but is not entirely unlike the Danio nigrofasciatus in appearance. Laubuka dadiburjori is a gold/silver fish with a blue line, it has two colour morphs, one with a distinct blue line, the other with a dotted blue line. Barbels are not present. Like most Danionins, this fish has a tendency to jump.
|
|
Acanthodoras species may be kept as pet fish in the aquarium fish hobby. They will accept a wide variety of foods. Due to their behavior of digging through the substrate for their food, sand or round gravel should be used to prevent damage to their barbels. There should be some shelter for these fish to hide under; once released into the aquarium, these fish may virtually never be seen again.
|
|
It also has long barbels, which are white on females and tan on males. Although this Pokémon is capable of surviving in even the most polluted ponds, it is usually overlooked by trainers because it is pathetically weak. Even in the heat of battle it will do nothing but flop around. They are normally seen using Splash, which is unusual, as it makes them easy targets to predators.
|
|
The walking catfish has an elongated body shape and reaches almost in length and in weight. Often covered laterally in small white spots, the body is mainly coloured a gray or grayish brown. This catfish has long-based dorsal and anal fins, as well as several pairs of sensory barbels. The skin is scaleless, but covered with mucus, which protects the fish when it is out of water.
|
|
The starry sturgeon reaches about in length and weighs up to . It is a slim-bodied fish easily distinguished from other sturgeons by its long, thin and straight snout. A row of five small barbels lies closer to the mouth than to the tip of the snout. The scales on the lateral line number between thirty and forty and these features distinguish this fish from the Russian sturgeon (Acipenser gueldenstaedtii).
|
|
The lateral line has an irregular zigzag pattern. The head is flattened anteriorly with a terminal mouth. There are three pairs of thread- like barbels, one pair maxillary and two pairs mandibular. The dorsal fin and pectoral fins have large spines; the dorsal fin spine has a lower degree of serration than the pectoral fin spines, which is always serrated strongly on the entire length of both margins.

Ozark madtoms have yellow spherical eggs. Their eggs adhere to each other but to no other surfaces. After about 4 days after spawning, the embryos obviously show blood, myomeres are well developed, the tail is free from the yolk sac, pigment is well developed in the eye, and a couple sets of barbels are beginning to form. At hatching, the larvae are 8 mm (0.3 in) long and mostly translucent.

Scaphognathops bandanensis, the common name, "Bandan sharp-mouth barb" is a freshwater fish in cyprinid family native to the Mekong basin in Indochina. It is characterized by small head is triangular and without barbels. Specific name bandanensis, refers to Amphoe Bandan (now Amphoe Khong Chiam), Ubon Ratchathani Province where the type series was collected. It was studied and described by two Thai fisheries academics, Sithi Boonyaratpalin and Mali Srirungroj.

Species of Cheirocerus have a fully ventral mouth with relatively fleshy lips, a broad premaxilla, a crimped gas bladder that appears to have fringe or finger-like projections, and the slender hollow tube extensions on each side of the gas bladder. These fish have an undeveloped dorsal fin locking mechanism and no dorsal fin spine. They also have a relatively long adipose fin. These species all have three pairs of barbels.
|
|
Juveniles of the Chinese high-fin banded sharks are also characterized by high and triangular dorsal finnage that extends up to the rear of the anal fin. The adult appearance is far less distinctive, as they are elongated in shape without the very high dorsal fin. The thick and fleshy lips bear small papillae without barbels. They have a single row of pharyngeal teeth that have comb-like arrangements.
|
|
The outer pair of mandibular barbels is a little under twice the length of the inner pair. They have short branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. ornatipinnis, the spine of the dorsal fin is about to times as long as the head, slightly curved, smooth in the front and serrated on the back.
|
|
The mandibular barbels have short and broad branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. marmoratus, the spine of the dorsal fin is short, about half the length of the head, smooth in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.
|
|
Adults of this species have highly arched backs and a short pair of barbels on the upper jaw at the corners of the mouth. The back is light to reddish brown, the sides are metallic green or yellow-green, with a brassy or golden sheen below. The belly is whitish, turning orange-red in males at mating time. Females can be distinguished by their dull colors and their overall bulk.

Studies on African Cyprinidae. Part II. Bulletin of the British Museum, 26 (1): 3-148. Thus, Barbus is for the time being restricted to the typical barbels and barbs, and only contains fishes from Africa and Europe, as well as adjacent Asia. However, the genus even in the reduced version is probably paraphyletic, and many African species (particularly the small ones) do not seem to belong here either.
|
|
It has a rather deep body with a large eye and noticeably protruding upper jaw. The maxillary barbels are very long, reaching the deeply forked caudal fin, when stretched along the body. Among the other characteristics which distinguish it from its congeners is the rather long adipose fin. The specific name honours the Austrian naturalist Johann Baptist Emanuel Pohl, who collected specimens in the São Francisco basin in the 19th Century.

|
O. marapoama reaches a maximum of about 4 centimetres (1.6 in) SL. Otothyropsis differs from closely related genera in its pattern of odontode growth, which grows under the snout unlike in other genera. Also, the body and abdomen is almost entirely covered in armor plates, which differs from closely related species which have less armor on the belly. These fish have round lips that form a suckermouth with maxillary barbels.
|
|
The outer pair of mandibular barbels is a little under twice the length of the inner pair. They have short branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. soloni, the spine of the dorsal fin is a little shorter than the length of the head, smooth in the front and serrated on the back.

The beardfishes consist of a single extant genus, Polymixia, of deep-sea marine ray-finned fish named for their pair of long hyoid barbels. Until recently they were classified in their own order Polymixiiformes. But as Nelson says, "few groups have been shifted back and forth as frequently as this one, and they were recently added to Paracanthoptergii". For instance, they have previously been classified as belonging to the Beryciformes.

|
Steindachneridion species are large fish, reaching 100 cm (40 in) in total length or more. S. doceanum reaches 42 cm (17 in) in standard length. S. melanodermatum reaches a length of about 53.2 cm (21 in) SL. S. punctatum reaches about 70 cm (28 in) SL. These fish have relatively small eyes and heads. They have long maxillary barbels that extend to the base of their dorsal fins or adipose fins.

Luciobarbus graecus is a ray-finned fish species in the family Cyprinidae. It is here placed in Luciobarbus following the IUCN, but that genus is very closely related to the other typical barbels and perhaps better considered a mere subgenus of Barbus. Found in and adjacent to Greece, its closest living relative seems to be L. lydianus, which is found in the northwest of Asia Minor.Crivelli (2006), de Graaf et al.
|
|
Barbus plebejus can reach a maximum length of 70 cm in males and a maximum weight of 6 kilograms. Usually, it is much smaller. It has a long and slender body, with a mouth equipped with characteristic four barbels (hence the common and genus names). It has greenish back with black dots, sides finely dotted, whitish belly, paired fins tinged with grey and a slightly thorny dorsal ray.
|
|
The phylogenetic position of Metaloricaria remains uncertain. Though classified in the tribe Harttiini in the subfamily Loricariinae, the length of the maxillary barbels (longer than in all other Harttiini), low number of teeth and their reduced size, reduction of the number of caudal-fin rays, and sexual dimorphism reminiscent of that seen in the Rineloricaria group, tend to support a closer relationship of Metaloricaria with the tribe Loricariini.
|
|
Like the other members of the Pristiophorus family, the common sawshark can be identified by a long snout with rows of small teeth and barbels on either side. It has five gill slits on either side of its head and between 19 and 25 teeth on each side. Sawsharks appear to be one of the types of elasmobranch that are difficult or impossible to age using most commonly-used approaches that rely on vertebral banding.
|
|
The tail is long, but difficult to tell apart from the rest of the shark. Its body is grey to brown in color with a broad black collar, from which it gets its name, and white spots along its body. It has small spiracles and nostrils with short barbels, likely used for sensory purposes. It is often mistaken for a species of catshark, despite being more closely related to wobbegongs and nurse sharks.
|
|
The Arabian carpetshark has a long tail and is uniformly brown in color. The Arabian carpetshark has a slender, nearly cylindrical body and a relatively long, thick, rounded snout. The nostrils are set a good distance from the snout tip and preceded by a pair of short barbels. The eyes are medium-sized and placed high on the head, each with a low ridge above and a large spiracle behind and below.
|
|
The peamouth is a slender fish, with a somewhat compressed body and a subterminal mouth, large eyes, a rounded snout and a forked tail. It has a dark back, contrasting with silvery underparts separated by two dusky, longitudinal stripes. The mouth is reddish at the corners where there are small barbels. When breeding the mature males develop a red stripe along the sides on the belly, mouth, gill cover and pectoral fin base.
|
|
They are able to produce sounds; every basic unit of the sound they emit when they move their pectoral spine lasts 100-200 milliseconds and has a frequency of 170-250 hertz. The barbels of the males are brown and yellowish white striated, the females monochrome yellowish white. The soil should be fine-grained and contain peat. When using gravel, the fish need at least a sand blanket, which is free of plants.
|
|
Finally, the lateral armor of doradids, Sisor, and hoplomyzontines consists of hypertrophied lateral line ossicles with dorsal and ventral lamina. The channel catfish has four pairs of barbels. All catfish other than members of Malapteruridae (electric catfish), possess a strong, hollow, bony leading spine-like ray on their dorsal and pectoral fins. As a defense, these spines may be locked into place so that they stick outwards, which can inflict severe wounds.
|
|
The kuhli loach is an eel-shaped fish with slightly compressed sides, four pairs of barbels around the mouth, and very small fins. The dorsal fin starts behind the middle of the body, and the anal fin well behind this. The eyes are covered with transparent skin. The body has 10 to 15 dark brown to black vertical bars, and the gaps between them are salmon pink to yellow with a light underside.
|
|
Pattern on head of wind-dried specimen View of head showing prominent nostrils and barbels Quite common within its range, the leopard catshark is harmless to humans. It is a popular subject of public aquariums because of its small size, attractive appearance, and hardiness. The aquarium trade supports a minor fishery that targets the two Poroderma species. This shark is regularly caught incidentally by commercial and recreational fishers, and almost invariably discarded despite being edible.
|
|
The outer pair of mandibular barbels has three simple branches, and the inner pair has five or six simple branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. courteti, the spine of the dorsal fin is about half the length of the head, smooth in the front. The remaining portion of the dorsal fin is made up of seven branching rays.
|
|
Goatfishes are pelagic spawners; they release many buoyant eggs into the water which become part of the plankton. The eggs float freely with the currents until hatching. The larvae drift in oceania waters or in the outer shelf for a period of 4–8 weeks until they metamorphose and develop barbels. Soon thereafter most species take of bottom-feeding life- style, although other species remain in the open water as juveniles or feed on plankton.

The tadpole cod (Guttigadus globosus) is a deepwater fish found in the oceanic islands off New Zealand and in the mid South Atlantic at depths ranging from 1200 to 1600 m. The tadpole cod is a member of the family Moridae, the morid cods, related to the true cods (of genus Gadus, family Gadidae). Like the familiar Atlantic cod, it has small whiskers (barbels) on its mouth. Specimens have been measured up to 18 cm.
|
|
Upper and lower side of head The Russian sturgeon can grow to but a more normal size is . It has a relatively short and rounded snout with three pairs of unfringed barbels closer to the tip of the snout that to the mouth. The dorsal fin has 27 to 48 soft rays and the anal fin has 16 to 35. The number of scales along the lateral line varies from 21 to 50.
|
|
Juveniles have scattered, irregularly-shaped spots on the body that become smaller with age. Most of the species of Synodontis of Lake Tanganyika have a recognizable pattern consisting of dark triangles at the bases of all of the rayed fins, present in S. irsacae when young, and the back edges of the fins are white in color. The caudal fin is black with white on the very end. The barbels are white.
|
|
In 1389 the town finally was acquired by Landgrave Balthasar of Thuringia, a member of the House of Wettin. Saalfeld's economy prospered from surrounding mines, transport on the Saale River as well as from fishing (expressed by the barbels in the town's coat of arms). The Wettin rulers had the Gothic Saint John hall church erected at the site of a Romanesque predecessor building until 1514. The Gothic town hall was completed in 1537.
|
|
The outer pair of mandibular barbels is about to as long as the head, and the inner pair is as long as the head., both with long, slender branches with secondary branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. smiti, the spine is a little shorter than the head, slightly curved, smooth in the front and serrated on the back.
|
|
The number of teeth on the mandible is used to differentiate between species; in S. sorex, there are about 6 to 8 teeth on the mandible. The color of the fish is grey on the back and sides, becoming white on the underside. The fins are light-colored, with a distinct blotch on the dorsal fin near the base, and a dark band on each lobe of the caudal fin. The barbels are white.
|
|
The emerald catfish is a common species in freshwater aquaria. It is a peaceful, undemanding species and can be maintained under the same conditions as most Corydoras species. They are shy and easily frightened when kept as individuals, so it is best kept in small groups of at least three, with more being recommended. The tank should have only a soft, fine bottom to prevent damage to barbels and should be heavily planted.
|
|
The scales are small. As with many deep-living fish, the lateral line system in grenadiers is well-developed; it is further aided by numerous chemoreceptors located on the head and lips and chemosensory barbels underneath the chin. Benthic species have gas bladders with unique muscles attached to them. The animals are thought to use these muscles to "strum" their gas bladders and produce sound, possibly playing a role in courtship and mate location.
|
|
The stone loach (Barbatula barbatula) is a European species of fresh water ray-finned fish in the family Nemacheilidae. It is one of nineteen species in the genus Barbatula. Stone loaches live amongst the gravel and stones of fast flowing water where they can search for food. The most distinctive feature of this small fish is the presence of barbels around the bottom jaw, which they use to detect their invertebrate prey.
|
|
The Danube gudgeon grows to a maximum length of , though a more normal size is . It has a distinctive pair of barbels at the corner of the mouth which are long enough to extend back to beyond the eyes. These are tactile organs and are used to search through sediment for edible items. There are no scales on the throat and this helps distinguish it from its close relative, Kessler's gudgeon (Romanogobio kessleri).
|
|
The bluegrey carpetshark has a stout body with a long, slightly flattened head. The snout is blunt and looks wedge-shaped from the side. The large eyes are horizontally oval and placed high on the head, each with a strong ridge underneath and a large, round spiracles following immediately behind and below. The nostrils are preceded by a pair of long barbels, which have an enlarged posterior flap halfway along their lengths.
|
|
Brachaelurus (blind sharks) is the sole genus of sharks in the family Brachaeluridae in the order Orectolobiformes. Only two species of blind sharks occur, both of which are native to shallow coastal waters up to deep, off the eastern coast of Australia. They are distinguished by the presence of long barbels, large spiracles, and a groove around the nostrils. They have two dorsal fins, placed close together on the back, and a relatively short tail.
|
|
Its head is wide, flattened, and blunt, with small eyes on top and a pair of long barbels underneath. It has large pectoral fins, two nearly equal-sized dorsal fins placed far back on the body, and an anal fin placed close to the caudal fin. The blind shark feeds primarily on small invertebrates and bony fishes. It is aplacental viviparous with females bearing litters of 7-8 pups in the summer.
|
|
The barbeled houndshark (Leptocharias smithii) is a species of ground shark and the only member of the family Leptochariidae. This demersal species is found in the coastal waters of the eastern Atlantic Ocean from Mauritania to Angola, at depths of . It favors muddy habitats, particularly around river mouths. The barbeled houndshark is characterized by a very slender body, nasal barbels, long furrows at the corners of the mouth, and sexually dimorphic teeth.
|
|
In S. gouldingi, the eyes are large and conspicuous, the nasal barbels are present but very short, the snout region of the head is elongate, and the mouth subterminal and not suckerlike. It has an elongate body. The integument is very thin and transparent, and superficial muscles and some other internal structures are readily visible. This species grows to about 2.7 centimetres (1.1 in) SL. S. gouldingi has certain skeletal paedomorphic characteristics.
|
|
The weatherfish (Misgurnus fossilis) is a species of true loach that has a wide range in Europe and some parts of Asia. It is an omnivorous scavenger bottom feeder, using its sensitive barbels to find edible items. The diet mostly consists of small aquatic invertebrates along with some detritus. The weatherfish is long and thin which allows it to burrow through the substrate and navigate through places that deeper bodied fish would have trouble with.
|
|
The shortnose sawshark (Pristiophorus nudipinnis) is similar to the longnose sawshark; however, it has a slightly compressed body and shorter more narrow rostrum. It has 13 teeth in front of its barbels and 6 behind. The shortnose sawshark tends to be uniformly slate grey with no markings on its dorsal side and pale white or cream on its ventral side. Females reach around 124 cm (49 in) long, and males reach around 110 cm (43 in) long.
|
|
The average length of a Rineloricaria catfish is about 13 cm (5 in) long. The fish are long, slender, have no visible barbels, an erect dorsal fin, a very thin caudal peduncle, and a narrow face. Coloration of the fishes are usually light brown with darker blotches, and have a dark dorsal fin. They are also covered with bony plates and have a sucker disk mouth, as is common with most fish in the family Loricariidae.
|
|
The shore rockling (Gaidropsarus mediterraneus) is a mottled brown, small, elongated fish. This eel-like fish has three barbels on its head, with the second dorsal fin and the anal fin running the length of most of its body. These fins may be viewed moving in a continuous wave motion. The shore rockling is often confused with the five-bearded rockling (Ciliata mustela) and the larger three-bearded rockling (Gaidropsarus vulgaris), due to their similar colourings, shape, and habitat.
|
|
The whiskery shark (Furgaleus macki) is a species of houndshark in the family Triakidae, and the only member of its genus. This common shark inhabits the Australian continental shelf from Western Australia to the Bass Strait, to a depth of . It is demersal in habits and prefers rocky and vegetated habitats. Stout-bodied and almost "humpbacked" in form, the whiskery shark can be distinguished from all other members of its family by the presence of long nasal barbels.
|
|
Rhinodoras species are distinguished from other doradids by a unique combination of coloration (sides darkly mottled, usually with wide dark bars, light midlateral stripe absent) and lip shape (labial tissue thick, fleshy, considerably expanded at corners of mouth forming rounded flap-like extensions with entire margins, all surfaces rugose with low, rounded, and tightly spaced papillae, and distal margin of lower lip draped over bases of outer and inner jaw barbels, at times nearly encircling the latter).
|
|
It can reach a length of 150 cm, though lengths up to 40 cm are more usual. It is commercially fished for human consumption as well as being a popular gamefish with a reputation for being a good fighter when hooked. It is carnivorous in diet. It can be distinguished from other sperata species by its spatulate, blunt snout, relatively short barbels and mouth that is only 1/3 as wide as the head is long.
|
|
Its common name derives from its similarity to the glowlight tetra, a South American characin only distantly related to this fish. They get on well with all other Danio species except the giant danio. thumb thumb A less frequently traded geographical variant from the Putao area of northern Myanmar, known as the "northern glowlight danio", sometimes is referred to by a fictitious scientific name "Danio putaoensis". This variant is larger and has more vertical bars and longer barbels.
|
|
The outer pair of mandibular barbels is longer than the inner pair, and is about the length of the head. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. caudalis, the spine of the dorsal fin is short, about the length of the head, smooth in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.
|
|
The outer pair of mandibular barbels is about twice as long as the inner pair, have long, slender branches with secondary branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. geledensis, the spine is as long as the head, nearly straight, serrated in the front and smooth on the back. The remaining portion of the dorsal fin is made up of seven branching rays.
|
|
Most of the species of Synodontis of Lake Tanganyika have a recognizable pattern consisting of dark triangles at the bases of all of the rayed fins, present in S. ilebrevis, and the back edges of the fins are dusky in color. The caudal fin has a black bar that runs from the base of each lobe to the top of the fin. The barbels are white. The maximum standard length of known specimens is with a total length of .
|
|
Goatfishes are characterized by a pair of chin barbels (or "goatee"), which contain chemosensory organs and are used to probe the sand or holes in the reef for food. Their bodies are deep and elongated, with forked tails and widely separated dorsal fins. The first dorsal fin has 6-8 spines; the second dorsal has one spine and 8-9 soft rays, shorter than anal fin. Spines in anal fin 1 or 2, with 5-8 soft rays.

|
L. reinii) may well belong in Labeobarbus. The small barbs from Africa, by contrast, are quite distinct. They might even warrant establishment of a new subfamily - in particular if the Labeoninae are not included in the Cyprininae -, as they seem to be as distinct from barbels and typical carps, as these are from the garras (which are part of the disputed Labeoninae), rendering the old "Barbinae" paraphyletic. Within the small African barbs, several linages can be recognized.

Aquarium du Québec Rather than having true scales, the Atlantic sturgeon has five rows of bony plates known as scutes. Specimens weighing over 800 lb and nearly 15 ft in length have been recorded, but they typically grow to be and no more than . Its coloration ranges from bluish-black and olive green on its back to white on its underside. It has a longer snout than other sturgeons and has four barbels at the side of its mouth.
|
|
Like other fish found exclusively in caves, the skin of R. reddelli lacks pigment. The fish also lacks eyes, instead having various sensory organs for taste, smell, and touch; these can help it to orient itself in the total darkness and locate food. It is a small fish up to long, with a flattened head, a long dorsal fin, and a deeply forked tail. The three barbels on the chin are long and packed with sensory cells.
|
|
The outer pair of mandibular barbels has long, simple branches, and the inner pair has short and thick branches with secondary branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. fuelleborni, the spine of the dorsal fin is slightly shorter than the head, smooth in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.
|
|
Most of the species of Synodontis of Lake Tanganyika have a recognizable pattern consisting of dark triangles at the bases of all of the rayed fins, present in S. polli, and the back edges of the fins are whiter. The caudal fin has a black bar that runs from the base of each lobe to the top of the fin. The barbels are white. The maximum standard length of known specimens is with a total length of .
|
|
The caudal fin is cream with a dark brown band in the distal half and with a narrow midlateral prolongation. The barbels and pectoral spines are cream or light brown, with dark-brown spots, only present sometimes on the dorsal surfaces in B. cessator and B. insignis. Sexual dimorphism is exhibited by B. insignis. Males have the anus situated immediately in front of a genital papilla, which is located immediately posterior to the pelvic-fin base.
|
|
M. nheco is like other doradids. It has three pairs of barbels (one pair maxillary, two pairs mental), strong dorsal and pectoral fin spines. M. nheco is differentiated from all other doradids by having its scutes with thorns directed ventrally in adults, and from all doradids except Physopyxis cristata by having an incomplete lateral line. It has a smooth dorsal fin spine, as opposed to a serrated one; the only other genus with smooth dorsal fin spines is Anadoras.
|
|
The pectoral fins are positioned low, while the pelvic fins are along with the abdominal position. Prominent features of the shortnose sturgeon are the scutes, protractile tube-like mouth, and chemosensory barbels. Sturgeon tend to be long-lived, slow-maturing, and spawn infrequently, which have served the species well through evolutionary time but poorly to anthropogenic impacts like overharvesting, habitat loss, and degradation. Potential predators of the shortnose sturgeon include alligators, sharks, and other large fish such as catfish.
|
|
On the lower jaw, or mandible, the teeth of Syndontis are attached to flexible, stalk-like structures and described as "s-shaped" or "hooked". The number of teeth on the mandible is used to differentiate between species; in S. resupinatus, there are about 60 teeth on the mandible. The color of the fish is a pale greyish brown on the back and sides, and black on the underside. The fins are grey, and the barbels are whitish.
|
|
The mandibular barbels have long, slender branches, and the outer pair is about as long as the inner pair. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. woosnami, the spine of the dorsal fin is about the length of the head, slightly curved, smooth in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.
|
|
As loricariids, loricariinae species are characterized by a depressed body covered by bony plates, a unique pair of maxillary barbels, and modification of the mouth into a suckermouth. Members of the subfamily Loricariinae show a greater diversity of lip structures and shapes than other loricariids. Loricariines are characterized by a long and depressed caudal peduncle (rectangular cross-section) and by the absence of an adipose fin. They also show dramatic variation in body shape, lip morphology and dentition.
|
|
It can be found in portions of the White Nile, Blue Nile, and the Baro Rivers in northeast Africa, and the Chad, Niger, Senegal, and Gambia river basins in western Africa. It occurs in slow-moving waters and marshes bordering large rivers. Water temperatures in its native habitat range from . Synodontis batensoda is silver-green to blue-grey with black barbels and a blackish underside (thus its specific name, from Arabic بطن السوداء bațn sawdā' = "black belly").
|
|
Pseudupenus prayensis has a moderately compressed body with a head profile which is not markedly convex. It has a single spine on the rear margin of the gill cover and a pair of thick barbels below its chin. Both jaws are equipped with strong, conical teeth with a few of the outer teeth in the upper jaw being backward pointing and theser are obvious when the mouth is closed. There are no teeth on vomer and palatines.

|
The Andean catfish's natural habitats are the mountainous rivers, freshwater springs or aquifers, caves and inland karsts of four different drainage basins within the Imbakucha watershed. It is brownish gray in colour and has no scales; large adults can grow up to 150 mm. Like all other catfishes, it has barbels around the mouth which contain taste buds that help the animal find food at night. Its diet consists of other fish, frogs, snails, algae, and other aquatic organisms.
|
|
Grey to white in colour and lacking stripes, the Mekong giant catfish is distinguished from other large catfish species in the river by the near-total lack of barbels and the absence of teeth. The Mekong giant catfish once held the Guinness World Records' position for the world's largest freshwater fish in 2005. Attaining an unconfirmed length of , the Mekong giant catfish grows extremely quickly, reaching a mass of in six years. It can reportedly weigh up to .

Barbonymus is a ray-finned fish genus in the family Cyprinidae, containing some barb species. The genus was only established in 1999, with the tinfoil barb (B. schwanenfeldii) as type species; thus, these fish are sometimes collectively called tinfoils. The new genus was established in recognition of the fact that some large Asian "barbs", formerly rather indiscriminately lumped in Barbus (typical barbels and relatives), Barbodes (barb-like carps) and Puntius (spotted barbs), form a distinct evolutionary lineage.
|
|
It was originally proposed as a subgenus but has since been found worthy of recognition as a full genus. This genus is restricted to southern Africa; all of its species were formerly placed in Barbus, the genus of typical barbels and their relatives. One taxon was originally described as P. leonhardi - this, however, was a European fish for which the genus was erroneously proposed anew. It has since turned out to be nothing other than the barbel B. peloponnesius.
|
|
The nostrils are large and preceded by well-developed flaps of skin that reach the mouth; each flap bears two prominent barbels, which are smooth rather than fringed. The capacious, gently curved mouth is placed at the front of the head. There are long, deep furrows extending from the mouth corners onto and away from the lower jaw. The teeth number around 18 rows in both jaws; each is small and dagger-like, with a single sharp cusp.
|
|
The lake sturgeon has taste buds on and around its barbels near its rubbery, prehensile lips. It extends its lips to vacuum up soft live food, which it swallows whole due to its lack of teeth. Its diet consists of insect larvae, worms (including leeches), and other small organisms (primarily metazoan) it finds in the mud. Fish are rarely found in its diet and are likely incidental items only, with the possible exception of the invasive round goby.
|
|
The body is scaleless and the lateral line extends to the anal fin. The lip is thick and has an irregular outline and there are three pairs of barbels around the mouth, one maxillio-mandibular pair and two rostral pairs. The body colour is generally a light yellowish brown with an irregular pattern of grey brown mottles and a varying number of diffuse bars or blotches which can fuse towards the caudal fin to for vertical stripes.
|
|
Kessler's gudgeon is a shallow-bodied, silvery fish with a pointed snout that grows to a length of about or occasionally . It has a pair of barbels by the mouth which help it locate food and which are long enough to reach to the far side of the eye. The throat is scale-less and there are 40 to 42 scales along the lateral line. The dorsal fin is made up of eight or nine branched rays.

The river flows down the Lavanttal with the towns of Bad Sankt Leonhard, Wolfsberg and Sankt Andrä, until it reaches the Drava shortly before it crosses the border to Slovenia. The water quality has been affected by large-scale river regulations between the 1930s and 1980s. Most parts of the Lavant belong to the trout zone, while the lowest sections are characterised by barbels. The name Lavant stems from the Pre-Celtic period, meaning "shining river" in Indo- European.

The tasselled wobbegong can be readily identified by the fringe of dermal lobes on its head. The tasselled wobbegong is a very broad, moderately flattened shark. The head is wider than long, with a distinctive fringe of branching dermal lobes running almost continuously from the snout tip to the origins of the pectoral fins, including a "beard" on the chin. The nostrils bear long, branching barbels, and have grooves surrounding them and connecting them to the mouth.

Upeneus moluccensis has an elongated body which has a sub-cylindrical anterior portion which becomes compressed towards the tail with two dorsal fins which are well separated, with the second dorsal fin directly above the anal fin. The caudal fin is deeply forked. The chin bears a pair of barbels which do not extend past the margin of the preoperculum. The upper and lower jaws, the palatine and the vomer are covered in brush-like or villiform teeth.
|
|
Upeneus moluccensis prefers sandy or muddy substrates where it searches for its food, mainly benthic crustaceans using chemoreceptors on its barbels. As they grow larger fish form a greater part of their diet. In the Mediterranean they spawn from late July up to September, the spawn and larvae are planktonic, settling to a benthic habit at 4–5 cm in length and becoming sexually mature when they are about a year old, c. 10 cm in length.

Hagfish have no true fins and have six or eight barbels around the mouth and a single nostril. Instead of vertically articulating jaws like Gnathostomata (vertebrates with jaws), they have a pair of horizontally moving structures with tooth-like projections for pulling off food. The mouth of the hagfish has two pairs of horny, comb-shaped teeth on a cartilaginous plate that protracts and retracts. These teeth are used to grasp food and draw it toward the pharynx.Hyperotreti.

Blotched upside-down catfish are small, reaching a maximum of SL. Like other members of the family Mochikidae, they have large eyes, a large dorsal fin and three pair of barbels. These fish are adapted to spend most of their time upside-down. This is reflected in the fish's pigmentation – their bellies are darker than their backs, a form of countershading. These fish have lighter colors on the top of their bodies and darker colors below used for camouflage.

|
Upeneus pori has an elongated body and a rounded snout. The body is greyish or red-brown, darker on the back, and covered with grey or reddish brown spots which go as far as the lower flanks but with no or a very faint lateral stripe visible in freh specimens. There is a dark brown or red bar whicg runs vertically through the eye and the barbels located on the chin are white or yellow. The first dorsal fin is colourless.

The upper surfaces of their necks are scattered with blunt to pointed conical skin tubercles that do not appear to have any specialized follicular centres (Legler and Winokur, 1979). The species has a single pair of barbels on the lower jaw. The Fitzroy River turtle is capable of obtaining up to 70% of its oxygen needs from the water through its cloaca, in a process called cloacal respiration. This allows the Fitzroy River turtle to remain underwater for up to three weeks.

The African dwarf sawshark (Pristiophorus nancyae) is a small five-gill sawshark that lives off the coast of Mozambique. It was first discovered in 2011 when a specimen was caught off the coast of Mozambique at a depth of 1,600 ft. The African dwarf sawshark has since then been spotted off the coasts of Kenya and Yemen. It can be distinguished from other sawsharks by its location, and by having its barbels closer to its mouth than the end of its rostrum.

In 1993, Pangasius was one of two extant genera (along with Helicophagus) in the family Pangasiidae. At this point, it was split into four subgenera. Pangasius (Pangasianodon) included P. gigas and P. hypophthalmus and was diagnosed by the absence of mandibular barbels, the absence of teeth in adults and the presence of a single-lobed swimbladder. Pangasius (Pteropangasius) included P. micronema and P. pleurotaenia and was diagnosed by four lobes in the swimbladder and with multiple segments in the last lobe.

Plotosus lineatus can reach a maximum length of 32 cm (13 in). The body is brown with cream-colored or white longitudinal bands. The most striking feature of this species is in the fins, in fact the second dorsal, caudal and anal are fused together as in eels. In the rest of the body is quite similar to a freshwater catfish: the mouth is surrounded by four pairs of barbels, four on the upper jaw and four on the lower jaw.
|
|
The type species is Luciobarbus esocinus, for which the genus was established by Heckel in 1843. The type species scientific name essentially means "pike-like pike-barbel" (after the northern pike, Esox lucius), though a more aliteral translation would be "pike-like wolf-barbel". Like many other cyprinids, the present genus was long included in Barbus. It appears to be a very close relative of the typical barbels - which include that genus type species, Barbus barbus -, and may well warrant inclusion in Barbus.

Yellow goatfish are benthic feeders, using a pair of long chemosensory barbels ("whiskers") protruding from their chins to rifle through the sediments in search of a meal. They usually feed on smaller fish, hunting in a school during the day, and alone at night. Yellow goatfish can live solitary or in similar-sized groups, sometimes switching between groups. When hunting in groups, each goatfish can be either a chaser, directly attacking prey or as a blocker, surrounding prey hiding in coral.

Exceptions to this are the ariid catfishes, where the young retain yolk sacs late into juvenile stages, and many pimelodids, which may have elongated barbels and fin filaments or coloration patterns. Sexual dimorphism is reported in about half of all families of catfish. The modification of the anal fin into an intromittent organ (in internal fertilizers) as well as accessory structures of the reproductive apparatus (in both internal and external fertilizers) have been described in species belonging to 11 different families.
|
|
Males grow to a length of 112 cm, while females grow a bit larger at 120 cm. Its coloration is dark brownish bars, over the dorsal and lateral surfaces, and its dorsal and upper surfaced paired fins contain vermicular patterns. The ventral surface of the trunk is pale, with nasal barbels with branches, with up to 3 simple lobes, along with 3 to 4 branched lobes. The dorsal fin grows tall, with the first dorsal fin near the pelvic fins.

Epaulette sharks are named for the prominent black spot behind their pectoral fins. The epaulette shark has an elongated body, over half of which is comprised by the slender caudal peduncle. The snout is short and rounded, with the nares placed almost at the tip along with a pair of tiny barbels; there are grooves running from the nares to the mouth. There are 26-35 tooth rows in the upper jaw and 21-32 tooth rows in the lower jaw.

The family Cetopsidae includes species of small- to medium- sized catfishes which share an anal fin with a long base, the lack of nasal barbels, and, usually, a lack of dorsal and pectoral fin spines. In Cetopsinae, the swim bladder is highly reduced and is enclosed in a bony capsule. Cetopsines lack an adipose fin, while it may be present (though small) in Helogeneinae. Many species are characterized by small eyes obscured by a thick, overlying integument that make them appear blind.

|
It is probably a derived feature, but its function is not understood. Another unique feature is the exceptionally long barbels under the mandible. Proportionately, the Mary River turtle has the smallest head and largest hind feet of all the species within the catchment, which contributes to its distinction of being the fastest swimmer. The turtle is occasionally informally referred to as the green haired turtle due to the fact that many specimens are covered with growing strands of algae which resemble hair.
|
|
The caudal peduncle has a depth of 8.3-9.3% of the standard length. Its barbels are 18-24% of the standard length. There are 7-10 total bars on caudal fin, 3-6 bars on the upper lobe which are pale brown near the base and dark brown to black towards the margin while the lower lobe has 3-4 brown bars which darken towards the margin and the last 2 bars being completely dark brown or black and widening towards the margin.

The earliest fossils of Synodontis in East African are from the Early Miocene. Many Synodontis fossils are the spines because they are very sturdy and so they are preserved better. The fossils of spines that are found are used to determine the family or genera of the fish but it cannot determine the species. Synodontis species that have survived and are still living can be identified by the shape of their whisker like organs on their heads called barbels, which relate to touch.

It is, however, only convergent to the typical gudgeon subfamily (Gobioninae) and in fact among the closest relatives of the typical barbels (Barbus and the doubtfully distinct Luciobarbus) - if it is not actually their closest relative.de Graaf et al. (2007) It is found in Bosnia and Herzegovina and Croatia, where it inhabits the karst. It occurs in some creeks in the Livanjsko field, in the Cetina, Krka and perhaps Zrmanja Rivers, and it was successfully introduced to Lake Blidin and Busko Blato.

The first pair are called the maxillary barbels which are usually slightly longer than the other rostral pair. The Garra geba's dorsal-fin membrane is a pale cream color with a faint band of black between the rays. It also has around 4 or 5 black spots between the rays with its anal, pelvic, and pectoral fins usually being a pale creamy brown. The caudal fin on the Garra geba is a pale brown and its median rays are dark brown.

The Indian flying barb (Esomus danrica), historically flying barb, is one of the species known in the group flying barbs owing to their extremely long barbels. It was discovered as long ago as 1822 by Hamilton. However, it is rarely seen in aquaria. It is found in Myanmar, Nepal, Pakistan, Sri Lanka and India, it is found in many of the same localities as Danio rerio and Danio dangila, an example being the Jorai Rivulet, a tributary of the Sankosh river in Coochbehar district, West Bengal, India.

Fish of this genus have scaleless skin, three pairs of barbels (one maxillary and two mandibular), and small eyes located lateroventrally in a position about mid- length of the head. The body is laterally compressed, bearing a long-based anal fin that runs from the anus to the anterior margin of the caudal peduncle. The dorsal, pectoral, and pelvic fins have a narrow base and lack spines. The posterior margin of the caudal fin is either deeply forked or emarginate, depending on the species.

It has been noted that Pelteobagrus may not be monophyletic if species placed in Pseudobagrus and Coreobagrus were excluded. The taxonomy of this genus is unclear and many authorities treat it as a junior synonym of Tachysurus. Pseudobagrus species are small- to mid-sized bagrid catfishes. These fish all have an inferior mouth; narial openings widely separated; four pairs of barbels; top of head covered by skin in most species; two dorsal fin spines; pelvic fin small; and caudal fin emarginate, truncate or round.

A. transmontanus is distinguished by the two rows of four to eight ganoid bony plates between the anus and anal fin, with about 45 rays present in the dorsal fin. Coloring can range from gray to brownish on the dorsal side, paler on the ventral side, and gray fins. Barbels are situated anterior to the mouth, closer to the snout than the mouth. At sexual maturity, A. transmontanus can reach in length, while the maximum length recorded of any age class is , with common lengths around .

It has four pairs of short, barbels around the mouth. The ground colour is silvery, brownish to olive on the back and upper parts of the head. There are two dark grey to olive bands, the longest running along the lateral line from the upper gill cover to the caudal peduncle, where this band starts on the upper gill cover there is a dark humeral spot. The second shorter band runs from the beginning of the pectoral fins to the end of the anal fin.

Red variation of dash-and-dot goatfish are found in deeper waters The dash-and-dot goatfish has the twin chin barbels typical of goatfishes. The body color is white with a black to dark brown stripe (dash) reaching from the upper lip through the eye and along the body, followed by a black spot (dot) at the base of the caudal fin. Above the stripe, the body has a yellowish tint. Dash-and-dot goatfish from deeper water will usually have red stripes and spots.

Ictiobus, also known as buffalofish or simply buffalo, is a genus of freshwater fish common in the United States, but also found in Canada, Mexico, and Guatemala. They are the largest North American suckers, reaching up to in length. At up to 112 years, they can reach the highest known age for a freshwater teleost. They are sometimes mistaken for carp because of the flat face and large, silver scales running along the body, though they lack the whisker-like barbels common to carp.

The Biharian barbel (Barbus biharicus) is a species of ray-finned fish in the genus Barbus. It is found in the Sebes-Körös River in Hungary and Romania. A recent study, in 2016, discovered a new species of barbels, named as the Barbus biharicus, in the Danube river basin. It was also found that the rheophilic B. biharicus is different from the other three species found in that area (Barbus balcanicus, Barbus carpathicus and Barbus petenyi) as it has deeper head than B. carpathicus and B. petenyi.

Most of the species of Synodontis of Lake Tanganyika have a recognizable pattern consisting of dark triangles at the bases of all of the rayed fins, present in S. granulosus, and the back edges of the fins are white to yellowish in color. The caudal fin has a black bar that runs from the base of each lobe to the top of the fin. The barbels are white; the bases sometimes have scattered pigmentation. The maximum standard length of known specimens is with a total length of .

The outer pair of mandibular barbels is about twice the length of the inner pair, and both pairs have short, simple branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. nigrita, the spine of the dorsal fin is straight or slightly curved, to 1 times the length of the head, smooth in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.

For the first time, the Barbels also combined the functions of conning tower, attack center, and control room in the same space, another feature adopted for all subsequent US submarines. This was facilitated by the adoption of "push-button" ballast control, another feature of Albacore. Previous designs had routed the trim system piping through the control room, where the valves were manually operated. The "push-button" system used hydraulic operators on each valve, remotely electrically operated (actually via toggle switches) from the control room.

Most of the species of Synodontis of Lake Tanganyika have a recognizable pattern consisting of dark triangles at the bases of all of the rayed fins, present in S. lucipinnis, and the back edges of the fins are white in color. In addition, the fins have large, lightly-colored windows at the bases, most noticeable in the dorsal and anal fins. The caudal fin has a black bar that runs from the base of each lobe to the top of the fin. The barbels are white.
|
|
This species grows up to about 32.0 centimetres (12.6 in) SL and is distinguished from all other aspredinids by having 4+5 caudal fin rays. They are further distinguished from its close relatives by the absence of accessory maxillary barbels and the presence of well developed rows of unculiferous tubercles. P. cotylephorus is usually found in brackish waters on the soft bottoms of shallow, turbid water near to the mouths of rivers. reportedly it migrates into freshwater, though spawning is believed to take place in brackish water.

Fertile Corydoras panda eggs require approximately 3–4 days development time before hatching, if kept at a temperature of 22 °C. This development time will vary with temperature, taking longer in cooler water. Upon hatching, the fry are four millimetres long, translucent, but already possessing the basic ground colour of the species, and upon close examination, possess fully formed barbels. Even newly hatched fry possess at least some hint of the adult eye patches, and as the fry grow, these patches darken and become more prominent.
|
|
The snout has a row of unserrated spines along the sides and two rows of shorter thorn-like spines on the underside near the sides all the way from the tip to the nasal openings. Nostrils are oval and surrounded by a narrow raised rim. The spines are very slightly curved and alternate long (5 to 7 mm) and short (2 to 3 mm), 47 or 48 spines on either side of the snout. There is a pair of barbels located on either side of the snout.
|
|
The inner pair of mandibular barbels is about to as long as the outer pair, have long, slender branches with secondary branches, and a membrane in the outer half. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. membranaceus, the spine is to as long as the head, straight or curved, smooth on the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.

The morphology of K. shajii differs from all other known species of catfish and includes such features as the absence of dorsal fin; the presence of four pairs of barbels; an upwardly directed mouth, with a distinctly projecting lower jaw with 4 set of teeth; subcutaneous eyes; anal fin completely confluent with the caudal fin; anal and caudal fins together carry 70–74 fin rays; and no spines in any of the fins. These differences have led to its being assigned to its own family.
|
|
Akysids are small to minute fishes with cryptic colouration, tiny eyes, and completely covered with unculiferous plaques or tubercles. In some genera, some of the tubercles on the body are enlarged and arranged in distinctive longitudinal rows, the number of which may be diagnostic. The dorsal fin has a strong spine and a short base, and usually four or five soft rays and four pairs of barbels are found. Unusually among catfish, they have a low principal caudal fin ray count and more rays in the upper caudal fin lobe than the lower.
|
|
These large fishes are similar to carps in appearance and ecology. Members of the Cobitidae are common across Eurasia and parts of North Africa. A midsized group like the suckers,FishBase (2004b,c) they are rather similar to catfish in appearance and behaviour, feeding primarily off the substrate and equipped with barbels to help them locate food at night or in murky conditions. Fishes in the families Cobitidae, Balitoridae, Botiidae, and Gyrinocheilidae are called loaches, although the last do not seem to belong to the lineage of "true" loaches, but are related to the suckers.

|
It spends the daytime buried in the top layer of sand. It forages mostly at night and sometimes in the morning. As an ambush predator, when foraging, it poises in the streamlet channel where water is flowing, supported by a tripod formed by its pelvic and anal fins, spreading both its very long barbels and the filamentous dorsal and pectoral-fin rays, thus forming a kind of "drift-trap". When the fish intercepts food, it will lunge at these food particles; after lunging for a short distance, it will return to its previous hunting spot.
|
|
This behavior is similar to that seen in the tripod fish. Small trichopteran larvae (ingested with the sand cases) and ephemeropterans constituted a considerable portion of the gut contents in a study of Mastiglanis asopos, but their foraging behavior allows a varied diet which includes large chironomid larvae and small adult beetles that would not be consumed by other sand-dwelling animals. M. asopos grows to SL. This fish has long barbels and long first pectoral fin rays which are used for feeding. It also has an acuminate (tapered to a point) snout.
|
|
There are four pairs of barbels. The lateral line is poorly developed or absent. Both Amblyceps and Liobagrus species grow to about SL. Liobagrus is more stoutly built than Amblyceps, the nostrils are close together in Amblyceps and distinctly apart in Liobagrus, and Amblyceps species have a cup-like flap above the pectoral fins that is absent in Liobagrus. Also, Amblyceps has double-folded lips and fin margins pigmented differently from the background colour, while Liobagrus has single-folded lips and fin margins paler than the background colour.

Mullus auratus has a moderately elongated, cylindrical body with a steep forehead with its upper jaw extending as far as the eye. It has no teeth in the upper jaw but does have teeth in its palate. It has two long barbels on its chin which fold into a groove on the throat. It is a reddish colour on the back and whitish on the belly, there is a reddish stripe along the flank which runs from the snout to the caudal peduncle with between 2 and 5 paler yellowish stripes visible too.
|
|
Like many other "barbs", it was long included in Barbus. It appears to be a fairly close relative of the typical barbels and relatives - the genus Barbus proper -, but closer still to the large Near Eastern species nowadays separated in Carasobarbus. Barbus has been split to account for the improved phylogenetic knowledge which indicated it was highly paraphyletic in its wide circumscription -, it may be that Carasobarbus and some other closely related "barbs" (e.g. Labeobarbus reinii) are now included in Labeobarbus to avoid a profusion of very small genera.

Upeneichthys lineatus is found over sandy bottoms in sheltered waters such as in bays and harbours, where they use their sensory barbels to probe the sediment for prey. They will live over varying substrates ranging from smooth bottoms, to rock and shell adorned bottoms. They frequently forage over the seabed in small schools, at depths of . Their teeth are rather fine and they do not have crushing molar like teeth and their prey is small molluscs, crustaceans, echinoderms and fishes, also larger soft-bodied animals similar to polychaetes.
|
|
A flattened head allows for digging through the substrate as well as perhaps serving as a hydrofoil. Some have a mouth that can expand to a large size and contains no incisiform teeth; catfish generally feed through suction or gulping rather than biting and cutting prey. However, some families, notably Loricariidae and Astroblepidae, have a suckermouth that allows them to fasten themselves to objects in fast-moving water. Catfish also have a maxilla reduced to a support for barbels; this means that they are unable to protrude their mouths as other fish such as carp.
|
|
The outer pair of mandibular barbels is about as long as the inner pair, have long, slender branches with secondary branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. filamentosus, the spine is as long as the head, curved, smooth in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays, ending in a long elongated filament that is longer than the dorsal fin itself.
|
|
The outer pair of mandibular barbels is about twice the length of the inner pair, and both pairs have long branches. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. caudovittatus, the spine of the dorsal fin is slightly curved, long, about as long or a little shorter than the head, smooth or finely serrated in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.

G. aymonieri has been recorded as reaching at least SL and is the only species in the genus to have 9 branched dorsal rays and 36–40 lateral line scales.Quoting Kottelat (1998): "Distinguished from the other species of the genus in having 9 branched dorsal rays, 36–40 lateral line scales and no dark spots on pelvic and anal fins. Size up to at least 280 mm SL" The mouth is inferior with a special "sucker" modification which allows the fish to attach itself to smooth surfaces. No barbels are present.

In 1369, the Hongwu Emperor of China established a porcelain company that produced large porcelain tubs for maintaining goldfish; over time, people produced tubs that approached the shape of modern fish bowls. Leonhard Baldner, who wrote Vogel-, Fisch- und Tierbuch (Bird, Fish, and Animal Book) in 1666, maintained weather loaches and newts.Brunner, B: The Ocean at Home, page 25 It is sometimes held that the aquarium was invented by the Romans, who are said to have kept sea barbels in marble-and-glass tanks, but this is definitely not true.

Clariid catfish are characterized by an elongated body, the presence of four barbels, long dorsal and anal fins, and especially by the autapomorphic presence of a suprabranchial organ, formed by tree-like structures from the second and fourth gill arches. This suprabranchial organ, or labyrinth organ, allows some species the capability of traveling short distances on land (walking catfish). The dorsal fin base is very long and is not preceded by a fin spine. The dorsal fin may or may not be continuous with the caudal fin, which is rounded.

The carpet sharks are a diverse group of sharks with differing sizes, appearances, diets, and habits. They first appeared in the fossil record in the Early Jurassic; the oldest known orectolobiform genera are Folipistrix (known from Toarcian to Aalenian of Belgium and Germany), Palaeobrachaelurus (Aalenian to Barremian) and Annea (Toarcian to Bajocian of Europe). All species have two dorsal fins and a relatively short, transverse mouth that does not extend behind the eyes. Besides the nostrils are barbels, tactile sensory organs, and grooves known as nasoral grooves connect the nostrils to the mouth.

It is a small loach, growing between 7.3 to 15.4 cm (2.9 to 6.1 in) TL. The diet and behaviors of the large-scaled loach are just about the same as other true loaches. This loach is an omnivorous scavenging bottom feeder, and is equipped with three pairs of barbels used to detect edible items. They are able to breathe atmospheric oxygen, which allows it to survive in poor quality water or even on land for extended periods of time. Females develop eggs over the winter and reproduction occurs during the spring.

The outer pair of mandibular barbels is a little under twice the length of the inner pair; and the outer pair with moderately long branches and the inner pair with secondary branches present. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. robbianus, the spine of the dorsal fin is about to times the length of the head, slightly curved, smooth in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.

Aspredo aspredo is the only species of banjo catfish (order Siluriformes) in the genus Aspredo. This species originates from the lower portions of rivers from Venezuela to northern Brazil. It occurs in the Orinoco delta, through the Guianas, to the Amazon River to the island of Trinidad. A. aspredo is the largest species of aspredinid, reaching about 38.3 centimetres (15.1 in) SL. The maxillary barbels are attached to the head, the colouration is uniform without any pattern of dark saddles, and the unculiferous tubercles present in other aspredinids are highly reduced.

Hypsidoris is an extinct genus of catfish, classified within its own family Hypsidoridae, from the Eocene epoch of North America. Hypsidoris was about long, and looked similar to the modern catfish, also possessing sensitive barbels used to detect prey in murky waters. It also had a vibration-sensitive organ called the Weberian apparatus, which consisted of specialized vertebrae at the front of the spinal column which passed vibrations to the inner ear, using the swim bladder as a resonance chamber. For defense against predators, Hypsidoris had large spines at the front of each pectoral fin.

Hoplomyzon is a genus of banjo catfishes that are native to tropical South America. Hoplomyzon species are small, armoured aspredinids, growing up to 32 millimetres (1.3 in) SL in H. sexpapilostoma. Members of this genus are distinguished from all other aspredinids by having each premaxilla with two bony knobs superficially covered by fleshy papillae, the dorsal and ventral armor plates not overlapping, and 2-3 sets of paired pre-anal-fin plates. They also have the maxillary barbels adnate with the head and the pectoral spine less than one-quarter of the fish's standard length.

Pethia stoliczkana is a freshwater tropical cyprinid fish native to the upper Mekong, Salwen, Irrawaddy, Meklong and upper Charo Phraya basins in the countries of Nepal, India, Pakistan, Myanmar, Bangladesh, Laos, Thailand, China and Sri Lanka. P. stoliczkana is silver-green with a vertically elongated black blotch behind the gill opening, and a vertically elongated black blotch on the caudal peduncle. The dorsal fin of a sexually active male is red with a black margin and two rows of black spots. It has no barbels and the last simple dorsal ray is serrated posteriorly.
|
|
The number of teeth on the mandible is used to differentiate between species; in S. membranaceus, there are about 8 to 14 small teeth on the mandible. The color of the fish is silvery grey or whitish on the back and sides, with the lower parts and underside dark brown to black. The barbels are whitish, with a dark brown or black border on the membrane. Juveniles may have poorly defined dark blotches on the body and spots forming stripes on the fins that will fade with age.

The largest catch recorded in Thailand since record-keeping began in 1981 was a female measuring in length and weighing . This specimen, caught in 2005, is widely recognized as the largest freshwater fish ever caught (although the largest sturgeon species can far exceed this size, they are anadromous). Thai fisheries officials stripped the fish of its eggs as part of a breeding programme, intending then to release it, but the fish died in captivity and was sold as food to local villagers. Juvenile fish wear barbels that shrink as they age.

In Prague sea aquarium Asian arowanas are considered to be symbols of good luck and prosperity, especially by those from Asian cultures. This reputation derives from the species' resemblance to the Chinese dragon, considered an auspicious symbol. The large metallic scales and double barbels are features shared by the Chinese dragon, and the large pectoral fins are said to make the fish resemble "a dragon in full flight." In addition, positive feng shui associations with water and the colours red and gold make these fishes popular for aquaria.

The last two were formerly often included in the present genus, and their delimitation is still not entirely clear. In any case, the genus Schizothorax (and other "snowtrouts") are in turn related to such cyprinids as the typical barbels (Barbus sensu stricto and the doubtfully distinct Luciobarbus and Messinobarbus), Carasobarbus, Labeobarbus, Aulopyge and Cyprinion. They were thus placed in the subfamily Barbinae, which is quite paraphyletic however and thus here merged with the Cyprininae at least for the largest part (including the marinkas), becoming its junior synonym in the process.

Historically, many species of Puntius have been classified in several genera, including Barbus. Despite the reclassifications, the specific epithet remains the same in these - except in cases of homonymies - as Barbus and Puntius have the same grammatical gender. The closest living relatives of the spotted barbs are the genus Cyprinion and perhaps the genus Capoeta. These and the other "typical" barbs and barbels were formerly often separated as subfamily Barbinae, but this group is highly paraphyletic with regard to the Cyprininae and better merged there at least for the largest part (including Puntius).
|
|
They are believed to use a combination of sensors, including olfactory, tactile, and chemosensory cues detected by the four barbels, and electroreception using their ampullae of Lorenzini. The sturgeons' electroreceptors are located on the head and are sensitive to weak electric fields generated by other animals or geoelectric sources. The electroreceptors are thought to be used in various behaviors such as feeding, mating and migration. Many sturgeons leap completely out of the water, usually making a loud splash which can be heard half a mile away on the surface and probably further under water.

E. cirrhatus are bottom feeders and are known to eat their prey from the inside out. Their diet mainly consists of carrion, although they prey on live animals as well. Hagfish play an important role in the ecosystem, recycling nutrients contained in carcasses that sink to the sea floor.(IUCN, 2011) As the hagfish are practically blind except for their sensitivity to light they rely on the 6 sensory barbels that surround their mouths to find their way along the ocean floor and their singular nasal passageway to smell out their prey.

The blind shark has a stocky body and a wide, somewhat flattened head with a blunt snout. The small, oval eyes are situated high on the head and have strong ridges underneath; the oval spiracles are positioned behind and below and have obvious raised rims. The nostrils are placed almost at the tip of the snout and have long, tapering barbels in front and well-developed skin flaps and grooves around the incurrent openings. A pair of obvious grooves connect the nostrils to the small, almost transverse mouth.

The bluegrey carpetshark or Colclough's shark (Brachaelurus colcloughi) is an uncommon species of carpet shark endemic to shallow inshore waters off northeastern Australia. It is one of the two extant members of the family Brachaeluridae. The bluegrey carpetshark has a stocky body with a wide, slightly flattened head, dorsally placed eyes, and a pair of long barbels with posterior skin flaps. It has large pectoral fins, two dorsal fins of unequal size placed far back on the body, and a sizable space between the anal fin and the base of the caudal fin.

Trichomycterus trefauti is a species of pencil catfish presently only known from the upper basin of the São Francisco River in Minas Gerais state, Brazil. This is a small, cylindrical catfish (35–55 mm standard length) which can most readily be distinguished from its congeners by its uniformly grey colouring, marked only by a distinctive elliptical dark spot at the base of the caudal fin. Other notable features include widely spaced eyes, very long barbels, the extension of the first ray of the pectoral fin into a long filament and pelvic fins which completely cover the anus and urogenital openings.

As the name suggests, the main visual differences are the five-bearded rockling having five barbels around its mouth, whereas the three-bearded rockling has a significant redness to its brown colouring when compared to the shore rockling. Shore rocklings can also be eaten, as the flesh is also very tender. Shore rocklings live in rocks, feeding on both worms and crustaceans. They are distributed in the eastern Atlantic from the mid-Norwegian coast south to the Straits of Gibraltar and into the Mediterranean Sea, where it is found along the coasts of north-west Africa and southern Europe into the Black Sea.

Video clip Parupeneus forsskali can reach a common length of about , with a maximum length of in males. The Red Sea goatfish has a relatively elongate body and a pointed snout, with the twin chin barbels typical of goatfishes. These fishes have eight dorsal spines, nine dorsal soft rays and seven anal soft rays. The body color is white with a broad black to dark brown stripe, sometimes tending to reddish, reaching from the upper lip through the eye and along the body, followed by an irregular roundish black spot at the base of the yellow caudal peduncle.
|
|
The tail fin is formed by the joining of the second dorsal fin, the caudal fin, and the anal fin, forming a single, continuous fin. Some of these catfishes can inflict painful wounds; stings from Plotosus lineatus may cause death, however stings from other types of eeltail catfish causes stinging which usually resides up to two weeks from when the person was penetrated by its dorsal spines. They are bottom feeders and use the barbels around their mouths to detect food. Unlike most marine teleosts, eeltails have an extra- branchial salt-secreting dendritic organ for osmoregulation.

Following the introduction of wels catfish, some fishes' numbers are in clear and rapid decline. Since its introduction in the Mequinenza Reservoir in 1974, it has spread to other parts of the Ebro basin, including its tributaries, especially the Segre River. Some endemic species of Iberian barbels, genus Barbus in the Cyprinidae, were once abundant especially in the Ebro river but due to competition from and predation by wels catfish have since disappeared in the middle channel Ebro. The ecology of the river has also changed, as there is now a major growth in aquatic vegetation such as algae.

The outer pair of mandibular barbels is two to three times the length of the inner pair; and the outer pair with moderately long, slender branches and the inner pair with secondary branches present. The front edges of the dorsal fins and the pectoral fins of Syntontis species are hardened into stiff spines. In S. depauwi, the spine of the dorsal fin is about times the length of the head, nearly straight, sharp-edged in the front and serrated on the back. The remaining portion of the dorsal fin is made up of seven branching rays.

Early illustration of an angelshark from Les poissons (1877) One of the largest members of its family, female angelsharks can attain a length of and males ; the maximum reported weight is . This species shares in common with other angelsharks a flattened body and large, wing-like pectoral fins whose anterior lobes are not fused to the head. The head and body are very broad and stocky, with small eyes positioned dorsally and followed by a pair of larger spiracles. A pair of unadorned barbels occurs in front of the nares, as well as a smooth or weakly fringed flap.

The class overall was a somewhat smaller diesel-powered version of the nuclear submarines, the first of which entered service only three months after Barbel, having been laid down only 11 days later. Several features of the experimental were used in the Barbel-class design, most obviously the fully streamlined "teardrop" hull. Albacores single-shaft configuration, necessary to minimize drag and thus maximize speed, was also adopted for the Barbels, Skipjacks, and all subsequent US nuclear submarines. This was a matter of considerable debate and analysis within the Navy, as two shafts offered redundancy and improved maneuverability.
|
|
This greatly conserved control room space and reduced the time required to conduct trim operations. The overall layout made coordination of the weapons and ship control systems easier during combat operations. The torpedo tube arrangement of the Barbels was the same as the Skipjacks, with six bow tubes in a three-over-three configuration. These (and the Skipjack-derived George Washington-class SSBNs) were the only US Navy classes to have this configuration, as subsequent SSN designs used four angled midships torpedo tubes to make room for a large bow sonar sphere, and most SSBNs had four bow tubes.
|
|
It also has tiny barbels at the corners of the mouth. The dorsal fin has 9-10 rays, while the pectoral fins have 16-19 rays, the pelvic fin 8-9 rays, and the anal fin 7-9 rays. Color is silver on the sides, with a dusky olive gray on the back; during the breeding season the fins pick up a red-orange tinge, and the males become darker and develop white tubercles on the head and at the bases of the fins. They feed on bottom- dwelling invertebrates and detritus, generally in areas of low to moderate current.

In traditional schemes, the family Diplomystidae is the basal, primitive sister group to all other catfishes (Siluroidei). This is well supported by morphological evidence. Almost all molecular estimates of catfish phylogeny, by contrast, find Diplomystidae sister to Siluroidei, with Loricarioidei (the armoured catfish and relatives) the most basal group; though this may be an artifact of rapid evolution in loricarioids. Diplomystids retain more plesiomorphic characteristics than any other siluriforms, recent or fossil, including aspects of the maxillary bones, barbels, nares, otic capsule, anterior pterygoid bones, Weberian complex centra, caudal skeleton, and fin rays, and pectoral girdle.

The stone loach is a small, slender bottom- dwelling fish that can grow to a length of , but typically is around . Its eyes are situated high on its head and it has three pairs of short barbels on its lower jaw below its mouth. It has a rounded body that is not much laterally flattened and is a little less deep in the body than the spined loach (Cobitis taenia) and lacks that fish's spines beneath the eye. It has rounded dorsal and caudal fins with their tips slightly notched, but the spined loach has even more rounded fins.
|
|
Its fins tend to be larger on average than in its relatives, and the anal fin usually begins somewhat closer to the fairly blunt (for a Luciobarbus) snout. Its eyes are large and the head is high and narrow by the standards of its genus. Like its relatives, it has four barbels, but these are slightly shorter on average than in its relatives. Unlike in L. lydianus, its lips are not markedly swollen and of equal size; it also lacks the black spot at the root of each body scale, but has a rather prominent black rim to each body scale.
|
|
Unlike most trichomycterids which are bottom- dwelling and nocturnal, T. longipinnis is nektonic and active both during daytime and at night, with juvenile and small adults being more active at daytime than large adults. This catfish uses visual, tactile, and chemosensory orientation to feed on bottom-dwelling aquatic and terrestrial insects in the water column or on the surface. Their diet includes immature aquatic insects, crustaceans, adult terrestrial winged insects, whole or fragmented, and carrion. These fish forage mostly by scanning the bottom, the barbels touching the substrate, but visually oriented drift feeding is also used by smaller fish.
|
|
The lips are thick, with an uninterrupted fold across the lower jaw, and with both the upper and lower lips in some specimens produced in the mesial line. The maxillary pair of barbels are longer than the rostral, and extending to below the last third of the eye. Fins the dorsal arises opposite the ventral, and is three fourths as high as the body; its last undivided ray is smooth, osseous, strong, and of varying length and thickness. Himalayan, Bengal, and Central Indian specimens generally have the spine strong, and from one half to two thirds the length of the head, it rarely exceeds this extent.

The fivebeard rocklings is a long, slender fish which may attain a length of . It has a smooth, scaleless body with unusual and long dorsal, which is made up of a first ray followed by a line of vibrating rays in a furrow in the back. The front part of the dorsal fin does not have any membrane connecting the rays although the rear dorsal fin is which runs the length of the body, as does the anal fin, is made up of rays connected by membrane. It has five barbels around its mouth, two above either nostril and a single barbel on the lower jaw.

The pyjama shark or striped catshark (Poroderma africanum) is a species of catshark, and part of the family Scyliorhinidae, endemic to the coastal waters of South Africa. This abundant, bottom-dwelling species can be found from the intertidal zone to a depth of around , particularly over rocky reefs and kelp beds. With a series of thick, parallel, dark stripes running along its stout body, the pyjama shark has an unmistakable appearance. It is additionally characterized by a short head and snout with a pair of slender barbels that do not reach the mouth, and two dorsal fins that are placed far back on the body.
|
|
Each nostril is split into tiny incurrent and excurrent openings by a flap of skin in front; the flap has a three-lobed shape with the central lobe forming a long, conical barbel. The barbels are thicker than in the leopard catshark, and do not reach the mouth. The eyes are horizontally oval and placed rather high on the head, with rudimentary nictitating membranes (protective third eyelids) and a thick ridge running underneath. The sizable mouth forms a broad arch, with short furrows extending from the corners onto both the upper and lower jaws; the upper teeth are exposed when the mouth is closed.

Squatina squatina, the angelshark or monkfish, is a species of shark in the family Squatinidae (known generally also as angel sharks), that were once widespread in the coastal waters of the northeastern Atlantic Ocean. Well- adapted for camouflaging itself on the sea floor, the angelshark has a flattened form with enlarged pectoral and pelvic fins, giving it a superficial resemblance to a ray. This species can be identified by its broad and stout body, conical barbels, thornless back (in larger individuals), and grayish or brownish dorsal coloration with a pattern of numerous small light and dark markings (that is more vivid in juveniles). It measures up to long.

Britski's catfish (Corydoras britskii) is a tropical freshwater fish belonging to the subfamily Corydoradinae of the family Callichthyidae native to South America where it is found in the upper Paraguay River basin in Brazil. This species was formerly classified as Brochis britskii.Encyclopedia of Aquarium and Pond Fish (2005) (David Alderton) page 121 The fish has a high number of dorsal fin rays (15–18) when compared with other Corydoras species. It has a shorter snout than C. splendens, a larger eye, grows to a larger size, and has its head covered ventrally by a large shield extending beyond the tip of the mental barbels.

The Cyprinidae are the family of freshwater fish, collectively called cyprinids, that includes the carps, the true minnows, and their relatives (for example, the barbs and barbels). Also commonly called the "carp family", or "minnow family", Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general, with about 3,000 species of which only 1,270 remain extant, divided into about 370 genera. They range from about 12 mm to the 3-m Catlocarpio siamensis. Fishbase-Catlocarpio-siamensis The family belongs to the ostariophysian order Cypriniformes, of whose genera and species the cyprinids make up more than two-thirds.

|
This pair formation consists of the male and female swimming parallel to each other, the male and female facing each other and contacting their barbels, the male stimulating the flanks of the female, the swimming to the surface by the male and female and production of the first bubbles at the nest site, and adding further bubbles to the nest under construction. The male produces most of the foam. First, the male and female come to the surface and swim belly-up in small circles. The film of the air- water interface is swallowed and pumped out through the gills, where it gains mucus.

The position of the gill openings separates them from the superficially similar, but generally much smaller (up to long) sawsharks, where the slits are placed on the side of the neck. Unlike sawfish, sawsharks also have a pair of long barbels on the rostrum ("saw"). Sawfish have two relatively high and distinct dorsal fins, wing-like pectoral and pelvic fins, and a tail with a distinct upper lobe and a variably sized lower lobe (lower lobe relatively large in Anoxypristis; small to absent in Pristis sawfish). The position of the first dorsal fin compared to the pelvic fins varies and is a useful feature for separating some of the species.

The Indonesian angelshark (Squatina legnota) is a rare species of angelshark, family Squatinidae, known only from a few specimens collected from fish landing sites in southern Indonesia. It is thought to inhabit the deep waters of the continental slope. Reaching at least long, this species has a flattened, ray-like shape and a well-developed tail and caudal fin. It is characterized by the absences of fringes on its nasal barbels and thorns down the midline of its back, as well as by its relatively plain grayish-brown dorsal coloration with dark saddles beneath the dorsal fin bases and a black leading margin on the underside of the pectoral fins.

Sometimes, they use their maxillary barbels (attached to the upper jaw) to lure prey fish closer to their mouths, similar to a worm jerking in the water, although this behavior is contested by some aquarists, who do not observe this behavior. When the catfish is ready to strike, the Chaca will open its large mouth rapidly, creating a vacuum that pulls in water and its prey, which may be up to half the fish's own length. These fish are also able to use this large mouths as a means of propulsion; when frightened, they will gulp a large amount of water and expel it through their gills.

The larvae of stone loaches are benthic, they and small juveniles prefer sandy substrates with a slower current, as they grow they move on to gravel bottoms and faster currents. As adults they prey on relatively large benthic invertebrates such as gammarids, chironomids and other insect larvae. It normally feeds at nights when it uses the barbels around its mouth to detect its prey. They are tolerant of moderate organic pollution and stream canalization but they are highly sensitive to heavy metal pollution, chemical pollution and low oxygen levels which mean that the presence of stone loaches in a river is an indicator of good water quality.

The gravel chub is a medium-sized minnow usually smaller than 10 cm. Its slender body is colored silver with an olive tint on the back and a white tint on the front, followed by a crosshatch pattern all over the scales. The gravel chub is often misidentified as the streamline chub, the gravel chub can be distinguished from the streamline by the more defined crosshatch marking and lack of dark blotches along the lateral line, which runs straight from the anterior to posterior end of the fish. The gravel chub is also defined by its subterminal jaw with barbels extending from both of the upper and lower maxillary jaw bone.

The two currently described species of Microcambeva have similar general morphology. M. ribeirae has a maximum recorded length of 4.8 centimetres (1.9 in) SL. M. ribeirae is distinguished from M. barbata by a series of morphological features, including the extent of the nasal barbels (to the nostril instead of the eye), the position of the eye (posterior half of head instead of on central portion), the first pectoral fin ray being shorter than the posterior ones (instead of the first ray being elongate and forming a prominent filament), the anal fin origin behind the vertical through the base of the last dorsal fin rays (instead of at this vertical), and others.

The Philippines angelshark (Squatina caillieti) is a species of angelshark, family Squatinidae, known only from a long immature female caught in the Philippines, where it is the only known representative of its family. It has a flattened body and head with greatly expanded pectoral and pelvic fins, and is greenish above with brown spots. Identifying traits of this species include the spiracles, which are more widely spaced than the eyes and bear papillae (nipple-shaped structures) on the posterior inner rims, and the relative positions of the two dorsal fins. Additionally, S. caillieti lacks fringes on its barbels, enlarged thorns along the middle of its back, and ocelli ("eyespots") on its fins.

In fish, barbels can take the form of small, fleshy protrusions or long, cylindrical shaped extensions of the head of a fish. The cylindrical barbel shapes are built on an internal support system that can be made from ossified tissue or from cartilaginous connective tissue that provides a base for blood vessels and myelinated nerves to wrap around, held together in the dermis. Muscle tissue in the central region of the barbel allows the structure limited movement that aids in prey manipulation. On the epidermis, taste buds are situated on dermal papillae, small ridges of folded skin that increase the surface area of the skin and the total number of taste buds that can be concentrated on the barbel.

Entomocorus species are small fish, growing to 5.3-7.0 centimetres SL. Sexual dimorphism is evident in all species except for E. benjamini; in this species, transformed males have yet to be found. In the other species, transformed males have stiff, ossified maxillary barbels, an elongated dorsal-fin spine, ventrally-directed pectoral-fin spine hooks, very elongated pelvic-fin unbranched rays, and a rotated anal-fin base. The four different Entomocorus species are not easily distinguished by differences in meristics or morphometrics; however, they can easily be distinguished by pigmentation, especially in caudal fin markings. In E. benjamini, the distal half of dorsal caudal fin lobe and the edge of the ventral lobe is pigmented.

More likely, the latter are part of the Cultrinae. The entirely paraphyletic "Barbinae" and the disputed Labeoninae might be better treated as part of the Cyprininae, forming a close-knit group whose internal relationships are still little known. The small African "barbs" do not belong in Barbus sensu stricto - indeed, they are as distant from the typical barbels and the typical carps (Cyprinus) as these are from Garra (which is placed in the Labeoninae by most who accept the latter as distinct) and thus might form another as yet unnamed subfamily. However, as noted above, how various minor lineages tie into this has not yet been resolved; therefore, such a radical move, though reasonable, is probably premature.

In the poem, Campbell vowed to, "flaunt Truth: :Before the senile owl-roosts of our youth :Whom monkeys' glands seem powerless to restore, :As Birth Control was profitless before, :Which sponsored by their mockery of a Church, :Like stranded barbels, left them in the lurch, :Whose only impact on the world's affairs, :Has been to cause a boom in Rubber shares, :Who come to battle with both arms held up :And ask to be invited home to sup - :While back at home, to sound their battle-horn, :Some self-aborted pedants stray forlorn :And pity those who venture to be born." James Matthew Wilson (2016), The Fortunes of Poetry in an Age of Unmaking, Wiseblood Books. Pages 16-17.

There is a small bar on the tip of the lower lobe. The width of biggest lower caudal-fin lobe bar and/or the space between outermost bars is less than the diameter of the orbit. They doi not have any flank stripes and the tip of first dorsal-fin is dark, The barbels are white as is the belly while the flanks are rose-red darkening towards the back where there is some gold iridescence along the upper flanks and a dark saddle to the rear of the second dorsal fin. The body is uniformly brown, with a little dorsal darkening, with the bars and black first dorsal- fin tip still visible in preserved fish.

It inhabits the slow-moving middle and lower parts of rivers and reservoirs in the Tagus' and the Guadiana Rivers' drainage basins. Its habitat are deep and almost stagnant waters with abundant aquatic vegetationCrivelli (2006) Its numbers have declined by about one-third since the 1990s due to unsustainable water usage for agriculture, pollution and competition with introduced species. Whether hybridisation with the more numerous L. bocagei also affects its numbers is not known. The two must have achieved reproductive isolation in the past to become as disting as they are, but damming and other construction have in recent times shifted the river's currents and changed microhabitat, so that these barbels will now meet at spawning sites more often.

This fly was originally created and used by sustenance fishermen in Japan,Tenkara Magazine, Volume One, 2014 hence its minimalistic construction. A quick and easy to build fly suited their purposes more so than a fly that required hard to get materials and a major investment in time. The most iconic version of the Sakasa Kebari is tied using nothing more than a hook, thread, and a feather, usually a pheasant feather. The hooks tend to be between sizes 16 through 12, the body being made solely with the thread, and the feather being wound around the front portion of the hook with the barbels angled forward, toward the eye, as opposed to backward the way most western flies are tied.

The New Zealand hagfish has a skull but no jaw or true vertebral column, it instead has a skeleton made up of cartilage.(Encyclopedia of Britannica, 2011) The rounded mouth of the hagfish is surrounded by 6 barbels, above that is their singular nasal passage and just inside the mouth is a dental plate with a row of posterior and anterior keratinous grasping teeth on each side. It has seven pairs of gill pouches and forming a line down both the lower sides of its body are pores which often many of them are ringed with a white colour and are used for secreting a snot-like slime which expands out once it has contact with the sea water.(Bray, n.

Their lower jaws usually have three rows of keradonts surrounded by a horny beak, but the number of rows can vary and the exact arrangements of mouth parts provide a means for species identification. In the Pipidae, with the exception of Hymenochirus, the tadpoles have paired anterior barbels, which make them resemble small catfish. Their tails are stiffened by a notochord, but does not contain any bony or cartilaginous elements except for a few vertebrae at the base which forms the urostyle during metamorphosis. This has been suggested as an adaptation to their lifestyles; because the transformation into frogs happens very fast, the tail is made of soft tissue only, as bone and cartilage take a much longer time to be broken down and absorbed.

The waters of the park are among Sweden's richest, which can be explained by a great number of factors, such as their optimal acidity, a great richness of nutrients, or even, among other things, the zones of rapids alternating with calmer zones. These waters permit the park have not only a great number of species, but also a great number of individual fish and certain fish of enormous size. Among the species present, one can name several species of cyprinids (the family of carp, minnows, barbs, barbels, and others), of which in particular the asp, rare in Sweden.p. 27 The waters abound also with northern pike, with specimens weighing sometimes , with European perch, with zander, and with grayling — which species is classified as endangered in Sweden, much like the brown trout.

The combination of the presence of a dorsal fin with an ossified spinelet and the presence of pectoral-fin and dorsal-fin spines distinguishes the species of Cetopsidium from all other genera in the Cetopsinae. A lateral line extending to over the posterior portion of the base of the anal fin but falling short of the caudal peduncle is also unique in this genus; the lateral line is usually longer than this, though it is shorter in two species of Denticetopsis. Cetopsidium species have mental barbels extending posteriorly beyond the rear margin of the opercle and a deeply forked, symmetrical caudal-fin margin with the tips of the lobes slightly blunt or rounded. The body is elongate to moderately robust; anteriorly the body is not compressed much, but becomes progressively compressed posteriorly.

The lips were once believed to be unable to function as a sucker while respiration continued, as the inflowing water would cause the system to fail; however, respiration and suction can function simultaneously. Inflowing water passing under the sucker is limited to a thin stream immediately behind each maxillary barbel; the maxillae in loricariids support only small maxillary barbels and are primarily used to mediate the lateral lip tissue in which they are embedded, preventing failure of suction during inspiration. To achieve suction, the fish presses its lips against the substrate and expands its oral cavity, causing negative pressure. Also, unlike most other catfishes, the premaxillae are highly mobile, and the lower jaws have evolved towards a medial position, with the teeth pointed rostroventrally; these are important evolutionary innovations.

It is the genus' type species, and indeed seems to represent a quite distinct lineage of large "barbs". It is not very similar to the barbels which are the core of the genus Barbus, and though closer to these than to some African barbs, they seem to be closer still to the common carp (Cyprinus carpio) and to Cyclocheilichthys than to either of the aforementioned. It is distinguishable from other species of the genus in having a red dorsal fin with a black blotch at the tip, red pectoral, pelvic and anal fins, red caudal fin with white margin and a black submarginal stripe along each lobe, and 8 scale rows between dorsal-fin origin and lateral line. Large individuals are silvery or golden yellow while alive with its dorsal fin red and caudal fin orange or blood-red.

The fish prefer a pH of 6.5-8.0 but will tolerate far more acidic conditions even for extended amounts of time with little negative reaction. This makes the pond loach a great choice for first-time aquariums and for those who want a hardy fish tank able to withstand a few mistakes. This fish should be kept in groups of at least 3, as they like to be in physical contact with each other and feel each other with their barbels when they rest. One trait which distinguishes the pond loach from most other tropical fish commonly seen at aquarium speciality shops and pet stores is the fact that they thrive at room temperature (68-72°F, 20-23°C) and can do well even at temperatures as low as the upper 50's Fahrenheit (13-15° Celsius).
