"The two oarfish were swimming vigorously in the nets," said Satomi Higa of the Yomitan's fisheries cooperative association.
|
|
At least a dozen oarfish had washed up onto Japan's coastline in the year prior to the disaster, according to Kyodo News.
|
|
The elusive oarfish live between 200 and 1,000 meters (650 to 3,200 feet) deep and are characterized by silvery skin and red fins.
|

"When their shrimp supply rises toward plankton during the daytime, the oarfish may sometimes follow and get caught in fishermen's nets," Inamura said.
|
|
The two oarfish, about 3.6 meters (12 feet) and 4 meters (13 feet) long, were found off the island's southwest Toya port on January 28.
|
|
One of the oarfish tore in half after being loaded onto a ship and was partially eaten by one of the fishermen, the Japan Times reported.

Consider the giant oarfish, a thirty-six-foot-long behemoth with a silver body, a bright-red mane, and a tendency to hang out in the ocean vertically, like a shiny piscine telephone pole.

Oarfish were first described in 1772. Rare encounters with divers and accidental catches have supplied what little is known of oarfish ethology (behavior) and ecology. Oarfish are solitary animals and may frequent significant depths up to . An oarfish measuring and was reported to have been caught in February 2003 using a fishing rod baited with squid at Skinningrove, United Kingdom.

The giant oarfish (Regalecus glesne) is a species of oarfish of the family Regalecidae. It is an oceanodromous species with a worldwide distribution, excluding polar regions. Other common names include Pacific oarfish, king of herrings, ribbonfish, and streamer fish. R. glesne is the world's longest bony fish.
|
|
The members of the family are known to have a worldwide range. However, human encounters with live oarfish are rare, and distribution information is collated from records of oarfish caught or washed ashore.

United States Navy SEALS holding a giant oarfish, found washed up on the shore near San Diego, California, in September 1996 Oarfish are large, greatly elongated, pelagic lampriform fish belonging to the small family Regalecidae. Found in all temperate to tropical oceans yet rarely seen, the oarfish family contains three species in two genera. One of these, the giant oarfish (Regalecus glesne), is the longest bony fish alive, growing up to in length. The common name oarfish is thought to be in reference either to their highly compressed and elongated bodies, or to the now discredited belief that the fish "row" themselves through the water with their pelvic fins.
|
|
Oarfish feed primarily on zooplankton, selectively straining tiny euphausiids, shrimp, and other crustaceans from the water. Small fish, jellyfish, and squid are also taken. Large open-ocean carnivores are all likely predators of oarfish.

Two deep sea oarfish were caught live in nets off the coast of Okinawa, Japan January 28, 2019. Both died before making their way into an aquarium inland in the town Motobu. One fisher described the two oarfish squirming in the nets as looking like "real dragons." A belief surrounds the species that they are "harbingers of earthquakes", but there is no scientific evidence or an association established between recorded oarfish sightings and earthquakes.

Regalecus russelii, or Russell's oarfish, is a species of oarfish in the family Regalecidae. It is a broadly-distributed marine fish, found in waters in the bathypelagic zone. R. russelii is a scaleless, elongate and ribbonlike fish, growing up to 8 meters in length.
|
|
Regalecus russelii is a member of the fish genus Regalecus and oarfish family Regalecidae. The genus currently includes only one other species of oarfish, Regalecus glesne. R. russelii is part of the order Lampriformes, which represents tube-eyes and ribbonfishes, and is part of the larger class of ray-finned fishes called Actinopterygii.

These markings quickly fade following death. It is probable that these markings are bioluminiscent in the deep sea. Oarfish that washed ashore on a Bermuda beach in 1860: The fish was long and was originally described as a sea serpent. The giant oarfish is by far the largest member of the family at a published total length of —with unconfirmed reports of and Bourton, Jody.

The giant oarfish and the related R. russelii are sometimes known as "earthquake fish" because they are popularly believed to appear before and after an earthquake.
|
|
In contrast, adult oarfish are rarely seen at the surface when not sick or injured. It is probable that the fishes go deeper as they mature.
|

The anal fin is completely absent and the caudal fin may be reduced or absent, as well, with the body tapering to a fine point. All fins lack true spines. At least one account, from researchers in New Zealand, described the oarfish as giving off "electric shocks" when touched. Like other members of its order, the oarfish has a small yet highly protrusible oblique mouth with no visible teeth.

The crested oarfish lives in warm seas, near areas such as the Western Atlantic, Western Indian Ocean, Eastern Atlantic, and the Eastern Pacific, in the oceanic and mesopelagic zone.
|
|
The oarfish is thought to inhabit the epipelagic to mesopelagic ocean layers, ranging from 200 meters (660 ft) to 1,000 meters (3,300 ft) and is rarely seen on the surface. A few have been found still barely alive, but usually if one floats to the surface, it dies. At the depths the oarfish live, there are few or no currents. As a result, they build little muscle mass and they cannot survive in shallower turbulent water.

R. glesne juvenile Little is known about oarfish behavior. It has been observed swimming by means of its dorsal fin, and also swimming in a vertical position. In 2010, scientists filmed a giant oarfish in the Gulf of Mexico swimming in the mesopelagic layer, the first footage of a reliably identified R. glesne in its natural setting. The footage was caught during a survey, using an ROV in the vicinity of Thunder Horse PDQ, and shows the fish swimming in a columnar orientation, tail downward.

Agrostichthys parkeri, also called the streamer fish, is a species of oarfish. Only seven identified specimens have been examined, with few found fully intact, and have mainly been found in the Southern Ocean. Agrostichthys parkeri belongs to the Regalecidae (oarfish) family in the Lampriformes order and is the only known member of its genus. This species has been known to grow up to 3 metres (around 10 feet) long and has a ribbon-like body, two large eyes, a protruding mouth and long filamentous rays originating at the head.

United States navy trainees display a giant oarfish discovered by their instructor on the beach of Naval Amphibious Base Coronado in 1996. R. glesne is not fished commercially, but it is an occasional bycatch in commercial nets, and as such it has been marketed. Because they are not often seen and because of their size, elongated bodies, and appearance, giant oarfish are presumed to be responsible for some sea serpent sightings. Formerly considered rare, the species is now suspected to be comparatively common, although sightings of healthy specimens in their natural habitat are unusual.

On 17 February 2003, a rarely seen oarfish was caught by angler Val Fletcher, using a fishing rod baited with squid. The fish was 11 ft 4 in (3.3 m) long and weighed 140 lb (63.5 kg). Graham Hill, the science officer at the Deep, an aquarium in Hull, said that he had never heard of another oarfish being caught off the coast of Britain. The Natural History Museum in London said that it would have been interested in preserving the fish in its permanent collection; however the fish had been 'cut up into steaks' before any scientists could examine it.

Spread through Japanese myth, the oarfish has been described as "messenger from the Sea God's Palace." Kiyoshi Wadatsumi, an expert in ecological seismology and director of e-PISCO, an organization which studies earthquakes, states that deep sea fish are more sensitive to the tectonic movements or tremors from active faults than fish closer to the surface of the ocean.

The Euteleostei or euteleosts is a clade of bony fishes within the Teleostei that evolved some 240 million years ago. It is divided into the Protacanthopterygii (including the salmon and dragonfish) and the Neoteleostei (including the lanternfish, lizardfish, oarfish, and the Acanthopterygii). The cladogram is based on Near et al. (2012) and Betancur-Rodriguez et al. 2016.

Numerically, actinopterygians are the dominant class of vertebrates, comprising nearly 99% of the over 30,000 species of fish.(Davis, Brian 2010). They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from Paedocypris, at , to the massive ocean sunfish, at , and the long-bodied oarfish, at .

His first book was published in 1995, Complete Wreck Diving (with co-author Henry Keatts). In 1996 he was the first to photograph a living Oarfish, an animal that inspired sea serpent legends. In 1998 Skerry received his first assignment for National Geographic Magazine. He has published 23 feature stories in National Geographic Magazine and contributed to 4 additional stories.

The body is scaleless and the skin is covered with easily abraded, silvery guanine. In the streamer fish (Agrostichthys parkeri), the skin is clad with hard tubercles. All species lack gas bladders and the number of gill rakers is variable. Oarfish coloration is also variable; the flanks are commonly covered with irregular bluish to blackish streaks, black dots, and squiggles.

In Southeast Asian folklore, the Phaya Naga (; ; ; literally: lord of nāga) are nāga, serpent-like creatures, believed by locals to live in the Mekong river or estuaries. Common explanations of their sightings have been attributed to oarfish, elongated fish with red crests; however, these are exclusively marine and usually live at great depths. People in both Laos and Thailand attribute the naga fireballs phenomenon to these creatures.

The species uses a feeding stance to see the silhouette of its prey. It feeds on euphausiid crustaceans, small fishes and squid, and uses its protrusile jaws to suck in prey. The oarfish mostly consumes a diet of krill as its energy source, using its jaw to fill its oro-branchial cavity with the crustaceans, that will then be held in the gullet and passed through.
|
|
C. longimanus feeds mainly on pelagic cephalopods and bony fish. However, its diet can be far more varied and less selective—it is known to eat threadfins, stingrays, sea turtles, birds, gastropods, crustaceans, and mammalian carrion. The bony fish it feeds on include lancetfish, oarfish, barracuda, jacks, dolphinfish, marlin, tuna, and mackerel. Its feeding methods include biting into groups of fish and swimming through schools of tuna with an open mouth.

B. elegans' taxonomic has been debated since its description in 1983. Because it appeared to combine features of both taeniosomid lamprids (i.e., its larval form resembles those of oarfish and ribbonfish), and of bathysomid lamprids (the anatomy of the pelvis is extremely similar to that of sailfins), it was attributed to an incertae sedis position within Lampriformes. Further research placed it within Zeiformes, another group of acanthomorph teleosts.

1895 illustration of Regalecus glesne Skeleton This species is the world's longest bony fish, reaching a record length of ; however, unconfirmed specimens of up to have been reported. It is commonly measured to in total length. The maximum recorded weight of a giant oarfish is . Its shape is ribbonlike, narrow laterally, with a dorsal fin along its entire length from between its eyes to the tip of its tail.
|
|
Its head is small with the protrusible jaw typical of lampriformes; it has 40 to 58 gill rakers, and no teeth. The organs of the giant oarfish are concentrated toward the head end of the body, possibly enabling it to survive losing large portions of its tail. It has no swim bladder. The liver of R. glesne is orange or red, the likely result of astaxanthin in its diet.

The giant oarfish is found worldwide in the upper layers of the open ocean (the pelagic zone). It is believed to be oceanodromous, following its primary food source. It has been found as far north as 72°N and as far south as 52°S, but is most common in the tropics to middle latitudes. It is thought to inhabit the sunlit epipelagic to dimly lit mesopelagic zones, ranging as deeply as below the surface.

Teleostei (Greek: teleios, "complete" + osteon, "bone"), members of which are known as teleosts, is by far the largest infraclass in the class Actinopterygii, the ray-finned fishes, containing 96% of all extant species of fish. Teleosts are arranged into about 40 orders and 448 families. Over 26,000 species have been described. Teleosts range from giant oarfish measuring or more, and ocean sunfish weighing over , to the minute male anglerfish Photocorynus spiniceps, just long.

The Norwegian municipalities of Fedje and Herøy both have oars in their coat-of-arms. Oars have been used to describe various animals with characteristics that closely resemble the said rowing implement. The members of the Family Regalecidae, elongated deep-sea fishes, are called oarfish because their body shape is similar to that of an oar. The hawksbill turtle's genus of Eretmochelys is derived from the Greek root eretmo, which roughly translates to oar.

Regalecus russelii lives in deep waters near areas such as Japan, California, and Baja California, in waters such as the Pacific, Atlantic, and Indian oceans. Since 1901, there have been 19 verified sightings and strandings along the coast of California waters. The R. russelii is found around the world equatorially, while the Regalecus glesne is found with antitropical distribution. The lack of live sightings of oarfish has made it difficult to determine the precise distribution of the Regalecus, and further research is needed.

A photograph on display in bars, restaurants, guesthouses and markets around Laos and Thailand captioned "Queen of Nāgas seized by the American Army at Mekhong River, Laos Military Base, on June 27, 1973, with the length of " is, as far as the caption goes, a hoax. The photograph itself is real, however, and was taken by Dr. Leo Smith of the Field Museum, of an oarfish found in September 1996 by United States Navy SEAL trainees on the coast of Coronado, California, USA.

Predatory teleost: the flesh- cutting teeth of a piranha (Serrasalmidae) There are over 26,000 species of teleosts, in about 40 orders and 448 families, making up 96% of all extant species of fish. Approximately 12,000 of the total 26,000 species are found in freshwater habitats. Teleosts are found in almost every aquatic environment and have developed specializations to feed in a variety of ways as carnivores, herbivores, filter feeders and parasites. The longest teleost is the giant oarfish, reported at and more, but this is dwarfed by the extinct Leedsichthys, one individual of which has been estimated to have a length of .

Ocean sunfish is the heaviest bony fish in the world The ocean sunfish is the heaviest bony fish in the world, while the longest is the king of herrings, a type of oarfish. Specimens of ocean sunfish have been observed up to in length and weighing up to . Other very large bony fish include the Atlantic blue marlin, some specimens of which have been recorded as in excess of , the black marlin, some sturgeon species, and the giant and goliath grouper, which both can exceed in weight. In contrast, Paedocypris progenetica and the stout infantfish can measure less than .

R. glesne was first described by Peter Ascanius in 1772. The genus name, Regalecus, signifies "belonging to a king"; the specific epithet glesne is from "Glesnaes", the name of a farm at Glesvær (not far from Norway's second largest city of Bergen), where the type specimen was found. Its "king of herrings" nickname may derive from its crownlike appendages and from being sighted near shoals of herring, which fishermen thought were being guided by this fish. Its common name, oarfish, is probably an allusion to the shape of its pelvic fins, or else it may refer to the long slender shape of the fish itself.

Dr. Paul LeBlond, director of Earth and Ocean Sciences at UBC, and Dr. Edward Blousfield, retired chief zoologist of the Canadian Museum of Nature, state every elongated animal has been put forward as an explanation for Caddy. These animals include Conger eels, humpback whales, elephant seals, ribbon or oarfish, basking sharks, and sea lions. LeBlond and Blousfield state no known creature matches the characteristics found in over 200 sightings collected over a century, noting that Caddy is described as having flippers both anteriorly and posteriorly. Darren Naish contends that LeBlond and Blousfield are engaging in bad science and have incorrectly assumed that different, conflicting eyewitness reports are all descriptions of one species.

The heaviest teleost is believed to be the ocean sunfish, with a specimen landed in 2003 having an estimated weight of , while the smallest fully mature adult is the male anglerfish Photocorynus spiniceps which can measure just , though the female at is much larger. The stout infantfish is the smallest and lightest adult fish and is in fact the smallest vertebrate in the world; the females measures and the male just . A rare giant oarfish (Regalecus glesne), long, captured in 1996 Open water fish are usually streamlined like torpedoes to minimize turbulence as they move through the water. Reef fish live in a complex, relatively confined underwater landscape and for them, manoeuvrability is more important than speed, and many of them have developed bodies which optimize their ability to dart and change direction.

In marine crustaceans, the trend of increasing size with depth has been observed in mysids, euphausiids, decapods, isopods, and amphipods. Non-arthropods in which deep-sea gigantism has been observed are cephalopods, cnidarians, and eels from the order Anguilliformes. Examples of deep-sea gigantism include the big red jellyfish, the giant isopod, giant ostracod, the giant sea spider, the giant amphipod, the Japanese spider crab, the giant oarfish, the deepwater stingray, the seven-arm octopus,, and a number of squid species: the colossal squid (up to 14 m in length), the giant squid (up to 12 m), Onykia robusta, Taningia danae, Galiteuthis phyllura, Kondakovia longimana, and the bigfin squid. Deep-sea gigantism is not generally observed in the meiofauna (organisms that pass through a 1 mm mesh), which actually exhibit the reverse trend of decreasing size with depth.
