Odontaster validus in Tokyo Sea Life Park Odontaster validus is an omnivorous scavenger and consumes anything it finds including carrion, detritus, the faeces of seals, red algae, bivalve shells, sponges, hydroids, other sea star, sea urchins, isopods, bryozoans, amphipods, crustacean larvae, ostracods, shrimps and diatoms. They have been observed aggregating on banks of mussels that have been exposed and damaged and on injured sea star, Acodontaster conspicuus. In turn, they are preyed upon by sea anemones and other species of sea star. It is an ecologically important species because of its consumption of benthic larvae and the control it exerts on the sea star Acodontaster conspicuus and the nudibranch Doris spp.

The species of starfish Astropecten articulatus, commonly known as the Royal Starfish is characterized by its bold colors. It has a purple granulated disk, which is the central region of the sea star, and the purple color continues to extend to its five flat rays, which are its arms. The margin of the sea star, which is its outline, is an orange color. Entomologist Thomas Say describes the sea star’s margin as “articulated throughout”, meaning that the orange margin that surrounds the sea star is continuous, even at the joints of its rays.

Research in 2014 showed that the cause of the disease is transmissible from one starfish to another and that the disease- causing agent is a microorganism in the virus-size range. The most likely candidate causal agent was found to be the sea star-associated densovirus (SSaDV), which was found to be in greater abundance in diseased starfish than in healthy ones.Netburn, Deborah (November 26, 2014) "Scientists find likely culprit behind mysterious sea star deaths" Los Angeles Times However, evidence for this virus as the cause of sea star wasting disease is inconclusive.

The population decline was associated with higher than normal water temperatures and the changes brought about by an El Niño event. The sea star almost became extinct in the gulf and had still not recovered in many parts by the year 2000. Because this sea star is a top-level predator, its virtual disappearance was expected to have profound effects on the ecosystem. However, the predatory rock snail Morula ferruginosa increased in abundance and kept the barnacles on which the sea star had previously fed under control, and the ecosystem in balance.

The nine-armed sea star is found at depths of up to around the coasts of Florida, in the Caribbean Sea, the Gulf of Mexico, and along the coast of South America to southern Brazil. It favours sandy, muddy or shelly seabeds in sheltered locations such as lagoons. It occupies the same range as the closely related gray sea star (Luidia clathrata) and has a very similar colouring but is easily distinguished by the number of arms, L. clathrata having just five.Luidia clathrata Gray sea star Smithsonian Marine Station at Fort Pierce.

Regarding A. articulatus, the study showed that it had very low levels of -glucosidase, but high levels of -glucosidase, and average levels of chymotrypsin. Since -glucosidase involves the degradation of detritus, it is bizarre that the sea star has relatively low levels of it because it contradicts the findings of Wells’ study: that the sea star consumes the shell of any mollusk regardless of whether or not there is an organism inside. Also, the high levels of -glucosidase indicate that the sea star also consumes high levels of plants, since that enzyme involves the degradation of plants. Lastly, even though Wells’ study found that the sea star consumes more organisms than other species of the same genus and is highly carnivorous, it is surprising that it doesn’t have as high chymotrypsin levels as others.

Kellet's whelk has been observed feeding together at the same time with the Giant sea star Pisaster giganteus on common food items and thus these two species are trophically interrelated. Pisaster giganteus also preys on Kelletia kelletii more often than any other motile gastropod, and yet the whelks do not appear to be eaten in proportion to their abundance or accessibility in studied localitions. The sea star appears to be a major predator of the whelk, even though Kelletia kelletii makes up less than 10% of the diet of the sea star. The whelk does not display an avoidance response in the presence of Pisaster giganteus.

Coexistence between the two species is believed possible as long as Kelletia kelletii does not become a preferred prey of the sea star. Usually these feeding convergences involved only a single sea star and two or three whelks. These convergent feeding groups were not limited to Kelletia kelletii and Pisaster giganteus. Kelletia kelletii has also been observed feeding interspecifically with two other sea stars, Dermasterias imbricata and Pisaster brevispinus.
|
|
Classic studies by Robert Paine established that when sea star predators are removed, mussel beds extend to lower tide heights, smothering resident seaweeds. Thus, mussels' lower limits are set by sea star predation. Conversely, in the presence of sea stars, mussels' lower limits occur at a tide height at which sea stars are unable to tolerate climate conditions. Competition, especially for space, is another dominant interaction structuring intertidal communities.

The sea star middle school gradually became notable within the community, a preschool was also established along with an elementary school. In 1997, due to high unemployment within the large population of Macau, Father Tan held the Jesus meeting once again. This resulted in the junior middle school degree diploma, the night four, center five and center six curricula being added to the school program. 46 years on and the Sea Star Middle School is still running.

Because Archbishop John Bede Polding was in Rome at the time, he was represented at the service by Aloys Elloy. After the end of the service the coffin and the silver container that held the heart of Louis d’Orléans were taken on board the Sea Star which was anchored at Circular Quay. On 2 June 1866 the Sea Star set sail for London with d'Orléans' remains. Also on board were Dr. Gingeot and the prince's retinue.

Zinc, and to a lesser extent nickel, lead, cadmium and silver accumulate in the body wall and the pyloric caeca (parts of the gut which project into the arms). In the Indian River Lagoon, a small brown polychaete worm sometimes lives on the surface of the sea star as a commensal. There may be several on one sea star and they probably benefit from the stirring up of the sediment caused by the sea star's activities.

There are around 40 different species of sea stars that have been affected by this disease. The disease seems to be associated with raised water temperatures in some places, but not others. It starts with the emergence of lesions, followed by body fragmentation and death. In 2014 it was suggested that the disease is associated with a single-stranded DNA virus now known as the sea star-associated densovirus (SSaDV); however, sea star wasting disease is still not fully understood.

Sea star pedicellariae may be located on the test's surface or mounted on flexible stalks. Depending on the species, pedicellariae may be surrounding the spines, on the surface of the animal's body, in pits on the abactinal, marginal, or actinal surface, and/or within the adambulacral plate adjacent to the tube foot furrow. Forcipulate sea star are so called because each pedicellaria is typically composed of three forceps-like valves. Other asteroids can have pedicellariae composed of only two components.

The gulf sea star is a predator and feeds on anything edible it can find including barnacles, bivalve molluscs, gastropod molluscs, sea anemones, chitons, sea cucumbers and crabs. Sea stars in this genus have planktonic feeding larvae that develop for many weeks before recruitment . In 1978, starfish wasting disease devastated the population of this sea star in the Gulf of California. Previous to that it was very common on rocks and under boulders in the lower and middle intertidal zone, with a density of up to one individual per square metre.

Considered the most beautiful and obvious of the Royal National Parks' sea anemone is the waratah anemone (Actinia tenebrosa) named after the waratah flower due to its corresponding flame red coloration. A common sea-star found growing in the rock pools is the biscuit sea star (Tosia australis). The fatally toxic blue-lined octopus (Hapalochlaena fasciata), the most common of the blue-ringed octopus species in the area, can, when touched, prove to be fatal within minutes. They are nearly impossible to spot unless pointed out, and can be found in small or large rock pools.

Paine first established the concept of a keystone species by studying the sea star. Robert Paine (1969) first came up with the concept of a keystone species while studying the effects of the predatory sea star Pisaster ochraceus, on the abundance of the herbivorous gastropod, Tegula funebralis. This study took place in the rocky intertidal habitat off the coast of Washington; Paine removed all Pisaster in 8m x 10m plots weekly while noting the response of Tegula for two years. He found that removing the top predator, in this case being Pisaster, reduced species number in the treatment plots.

Space competition is especially fierce in rocky intertidal habitats, where habitable space is limited compared to soft- sediment habitats in which three-dimensional space is available. As seen with the previous sea star example, mussels are competitively dominant when they are not kept in check by sea star predation. Joseph Connell's research on two types of high intertidal barnacles, Balanus balanoides, now Semibalanus balanoides, and a Chthamalus stellatus, showed that zonation patterns could also be set by competition between closely related organisms. In this example, Balanus outcompetes Chthamalus at lower tide heights but is unable to survive at higher tide heights.

The newly formed juveniles are the founding primary polyps of new colonies. Certain starfish prey on the orange sea pen. It can distinguish between the threats posed by the specialist predator leather star (Dermasterias imbricata), the generalist predator sunflower seastar (Pycnopodia helianthoides) and the ochre sea star (Pisaster ochraceus), which does not feed on sea pens. It reacts by emitting a flash of light and diving into the sand when contact is made by the leather star, sometimes behaves similarly when approached by the sunflower seastar and does not react defensively when touched by the ochre sea star.

|
The ampulla muscle layers in the tube feet allow for the tube feet to elongate and to shorten, which allows the sea star to move. Morphologically, A. articulatus is very similar to A. aranciaca. In the past, it was thought that a difference between the two species was that A. aranciaca has needle-like granules in its disk, the A. articulatus has spherical ones. However, a newer study has found that the granules are not spherical, and may have the appearance of that shape due to folding The sea star can be found on the east coast of the continental Americas, particularly in the Caribbean.
|
|
However, when prey is present, the A. articulatus start to exhibit more change in movement and speed. This means that when prey is present, A. articulatus alter their movement patterns so that they forage in areas with “higher prey density”, which is more evidence of the sea star foraging optimally. Lastly, the study found that the sea star forages twice a day, at dawn and dusk, which is similar to other species in the Astropecten genus. Overall, the feeding patterns of A. articulatus can be summarized as foraging optimally on mollusks and possibly plants, but also consuming more organisms than the typical starfish species.

This sea star has superomarginal plates with a very short spines or without spines (usually the plates between the arms are devoid of spines). The inferomarginal plate has a short and pot external spine, arranged with great regularity, normally kept parallel to one another and rather rigid. The inferomarginal spines have dark orange colour at the base and white- yellowish towards the tip on going to draw a sort of orange outline at the base of the sea star. The overall shape is very peculiar with bigger disc than other species and arms rather court, triangular and very pointed that accentuates the classic shape of the star.

|
On the dorsal side, the rays are rough with groupings of spinelets, each one have three to six glassy points. The sides of the rays are curving and smooth. The rays contain many of the organs in the sea star. On the tips of the rays are the eyespots.
|
|
Finally, the final arm releases the substrate and the free arms flip over the sea star resulting in a somersault motion. Furthermore, not only did a thermal increase result in a change in righting response, it also increased mortality rate in Echinaster and slowed metabolic response rates overall.

The winkles were more successful at gaining entry if they drilled between the wall plates of the barnacle rather than through them. Larger barnacles may be too big for the frilled dogwinkle (Nucella lamellosa), the purple seastar (Pisaster ochraceus) or the sunflower sea star (Pycnopodia helianthoides) to tackle.

There are 2 main competing hypotheses about the internal subdivision, both about equally well supported by both molecular and morphological data. They differ in their placement of the Ophiuroidea (brittle stars), and are named accordingly. The "Cryptosyringida" hypothesis posits that the "sea-star" morphology is plesiomorphic for Eleutherozoa as a whole, and that starfish (Asteroidea) and brittle stars are not very closely related, the latter forming the clade Cryptosyringida together with the Echinozoa. The "Asterozoa" hypothesis, on the other hand, implies that the "sea-star" arms of starfish and brittle stars, as well as the rounded shape of Echinozoa, all evolved independently from an ancestor of unknown morphology, but that each "armed" and "rounded" lineage is strictly monophyletic.

Once the shell is broken, the starfish inserts its stomach to digest the innards of the prey. Once the sea star is finished digesting its prey, it will swallow its own stomach back into its own body. After feeding, the starfish will leave white marks on the mussel, a remnant of the predatory relationship.

The tube foot rows are attached to the rays by ambulacral grooves. The Tube Foot Rows use a chemical adhesive to stick to surfaces instead of suction. The tube foot rows help the sea star stick to its prey, and to bring the prey to its mouth. The tube foot rows also aid in gas exchange.
|
|
It is covered by a thin membrane and sphincter. When the sea star has its prey, it extends the stomach to envelope the prey. Once the prey is enveloped, it then retracts back into the disc, and transfers it to the pyloric stomach for further digestion. The pyloric stomach has two extensions into each arm called the pyloric caeca.

The sea star is eating the bivalve Chama pellucida while three Kelletia kelletii are attempting to get to the prey. An avoidance response is a response that prevents an aversive stimulus from occurring. It is a kind of negative reinforcement. An avoidance response is a behavior based on the concept that animals will avoid performing behaviors that result in an aversive outcome.
|
|
In other species, individuals may aggregate during the reproductive season, thereby increasing the likelihood of successful fertilisation. Internal fertilisation has currently been observed in three species of sea star, three brittle stars and a deep water sea cucumber. Even at abyssal depths, where no light penetrates, synchronisation of reproductive activity in echinoderms is surprisingly frequent. Some echinoderms brood their eggs.
|
|
The margined sea star (Astropecten articulatus) is a well known molluscivore. It catches prey with its arms which it then takes to the mouth. The prey is then trapped by the long, moving prickles around the mouth cavity and swallowed food. In more advanced species of starfish, the cardiac stomach can be everted from the organism's body to engulf and digest food.

Video summarizing the impacts of ocean acidification. Source: NOAA Environmental Visualization Laboratory. Increasing acidity has possibly harmful consequences, such as depressing metabolic rates in jumbo squid, depressing the immune responses of blue mussels, and coral bleaching. However it may benefit some species, for example increasing the growth rate of the sea star, Pisaster ochraceus, while shelled plankton species may flourish in altered oceans.

|
The giant sea star only has a few predators. Sea otters and sea birds feed on giant sea stars, and their larvae are eaten by certain types of sea snails. They prey on several kinds of sea organisms including barnacles, gastropods, bivalves and limpets. It eats its prey by extending its stomach so it can fit into tiny gaps, such as mussel shells.
|
|
Henricia sanguinolenta shows behavioral adaptations in addition to physical ones. The sea star is usually seen with sponges and coral, using the currents they make to feed upon detritus. Henricia sanguinolenta is also one of the only species of sea stars that broods its eggs. The female stays with the eggs while they hatch, and continues to stay with them as larvae.

Echinaster brasiliensis: A-Spines of arm, B-Tube feet, C-Abactinal view of Arm. Starfish generally move by using their tube feet. Water enters through the madreporite and reaches the tube feet, causing an expansion and contraction of the tube feet, which moves the sea star. When fully inverted, Echinaster and other sea stars are able to exhibit a behavior known as righting.

The sea stars liberate their gametes into the sea where fertilisation takes place. The eggs hatch into bipinnaria larva which drift with the plankton. In about 25 days they have grown considerably and settle on the sea bed before undergoing metamorphosis into juvenile sea stars. In polluted waters, the nine-armed sea star has been found to concentrate heavy metals into its tissues.

Although no invertebrates have been identified as endangered or vulnerable, it is important to acknowledge that there are a plethora of invertebrates within the Cape Byron Marine Park which are critical to the health of the local ecosystems. These include a variety of molluscs such as the gold ring cowries (Cypraea annulus), Crustaceans such as the Zebra Shrimp (Ganthophylum americanum) and a specimen of the seven armed sea star (Luidia australiae). These Invertebrates have been noted as they are not usually found in areas and climates such as the Cape Byron Marine Park. The Zebra Shrimp and the seven armed sea star are rarely found in intertidal habitats and the gold ring cowries share a tropical affinity and demonstrate a rare occurrence in which the Cape Byron Marine Park is a habitat for both temperate and tropical species.

As they do not travel outside their tubes, these worms do not have any specialized appendages for swimming. Worms of the genus Serpula are commonly found attached to submerged rocks, shells, and even boats in many coastal areas around the world. They are found at depths ranging from intertidal to at least 800 meters. Predators include predatory starfish such as the Ochre Sea Star (Pisaster ochraceous).

He provided free elementary education for poor students who couldn't afford education elsewhere. He spread the gospel and witnessed to anyone that would listen, he also imitated Kong Zi and taught people from all walks of life without discriminating against them. Up until 1959, Father Ge followed orders assigned to him from Portugal. In 1959, Father Tan met other palm sea star school principals.

The red cushion star is the largest sea star found within its range, sometimes growing to about in diameter. It usually has five thick, broad arms projecting from a broad cushioned disc but some specimens have four, six or seven. The upper surface is hard and is covered with blunt spines. The colour of adults is some shade of red, orange, yellow or brown.

One such beaching, which occurred near Florence in November, 1970, was handled by blowing it up using dynamite. This has become the well- known exploding whale incident. Sea star and sea anemone at Bandon Beach tidepool Tidepools, which occur frequently along Oregon's rocky shores, are unique, contained ecosystems housing up to many hundreds of species of animal. Red, green, and brown algae are common sights.

Giant sea stars have small eggs, and their sperm contain spherical heads. Once their larvae are born, they are bilaterally symmetrical. By the time they mature and reach adulthood they are centered on a set point with radial symmetry to their bodies. The gonads of the giant sea star grow in a winters time just in time for spawning season between the months of March and April.

Blue Mussels are able to fight off one species of predator at a time such as sea star(Asterias Rubens (=Asterias Vulgaris)) or green crabs (Carcinus maenas). They use their inducible defenses to strengthen their adductor muscle or grow thicker shells. When faced with two species at a time, they are no longer able to use their defenses and can be killed more easily.

The nine-armed sea star has long, slim tapering arms attached to a small circular central disc. It grows to a diameter of about . The aboral or upper surface has a patchwork of closely packed spiny plates. The square ones near the edge of the arms are cream coloured and the irregular ones in a band running down the middle of the arms are grey.

Astrostole scabra, commonly called the seven-armed starfish, is a sea star in the family Asteriidae, native to New Zealand, eastern Australia and southern Australia. A frequent inhabitant of the intertidal zone also seen attached to wharf piles, it is among the larger sea-stars found in New Zealand. Adults often pray on mussels, forcing the shells open by applying pressure for long periods with the tube feet.

Horned sea stars seem to be opportunistic carnivores; adults are known to prey on most sessile life forms including hard corals and sponges in aquarium. In this same setting, they will hunt down snails and eat them. An individual of horned sea star also has been observed eating a sea urchin in their natural habitat. Gremli MS, Newman HE, Insight Guides Underwater: Marine Life In the South China Sea, page 159.
|
|
In many tropical Asian and Pacific countries, horned sea stars are collected for sea shell trade for their ornate skeletons. In some areas overharvesting is an issue and reduces greatly the population of the echinoderms. A related species, the Atlantic Oreaster reticulatus, commonly known as Bahama Sea Star, is also a once-abundant species reduced in number due to the continuous harvesting by the industry and tourists alike.

Onihito-Devil is the second in command of Evilcorp (Majimun) in season 1. He is based on the "Onihito" or Crown of Thorns Sea Star that can be found in the shallow water and coral reefs of Okinawa. These creatures are large and covered in hundreds of sharp spines that introduce a toxic venom into wounds they cause. In his human form he is Kanai's long lost older brother Nirai.

Akademik Vladislav Volkov, a Russian research vessel in the South Pacific, communicates with the orbiting space station Mir. A large energy source traveling through space strikes Mir, killing the cosmonauts and beaming itself down to Volkov. The electrical surge takes over the ship and attacks the crew. Seven days later, the tugboat Sea Star, captained by alcoholic Robert Everton (Donald Sutherland), loses its uninsured cargo while sailing through a typhoon.

On top of that, the recent arrival of two invasive species into the sea stars last remaining habitat, the kelp Undaria pinnatifida and the sea slug Pleurobranchaea maculata add potential threats. The kelp competes for space, not only the space of A. stellifera but also that of its prey. P. maculata has a large overlap of prey with A. stellifera, decreasing the amount available for the sea star.

The Sea Star arrived in London on 11 September 1866. After the end of the Second French Empire and the Paris Commune the family of Louis d'Orléans returned to France in 1871 from their exile in England. In 1885, the urn that contained the hearts of the Princes of Condé was placed in the chapel of Château de Chantilly. Here, too, is the final resting place of Louis d'Orléans' heart.

Being mainly sessile creatures, the C. bella is highly susceptible to predators like large fish and other marine organisms. They may also lose limbs due to abiotic stressors like great salinity and temperature fluctuations. On average, the feather-star is reported to lose an arm every 8 to12 days . As a survival mechanism, this crinoid has evolved to be able to lose and regenerate lost limbs, much like a sea-star.
|
|
The species is otherwise scarce in its distribution in the Pacific; its abundance is accommodated by the scarcity of its chief predator, the sea star Orthasterias koehleri. The reason for the sea star's disparity is unknown, as it is extremely common on nearby seamounts. The steeper flanks of the volcanoes are carpeted by coralline algae of the Lithothamnion and Lithophyllum genera. In some areas, Borgiola pustulosa is more common.

Although Dolittle is acquitted on the murder charge, the vindictive judge sentences him to a lunatic asylum. Dolittle's animal friends engineer his escape, and he, Matthew, Tommy, Polynesia, Chee-Chee and Jip set sail in search of the Great Pink Sea Snail. Emma, by this time fascinated by Dolittle, stows away, seeking adventure. They randomly choose their destination: Sea-Star Island, a floating island currently in the Atlantic Ocean.

The researchers thought it likely that there was increased mortality among infected males. In 2006, a mass die-off of the purple sea star (Pisaster ochraceus) occurred off the coast of British Columbia. Parasitism by Orchitophrya stellarum was considered to be the likely cause. A marine parasite expert stated that the starfish was an important member of the marine community and that if it were removed, marine biodiversity in the area would be threatened.

Neptune Memorial Reef was originally conceived as an art project called The Atlantis Reef Project and was envisioned and created by Gary Levine and Kim Brandell. Burial at sea became a way of financing the project. As of 2011, about 200 "placements" had occurred. Cremated remains are mixed with concrete and either encased in columns or molded into sea-star, brain-coral, castings of lions or other shapes before entering the water.

Acropora acuminata is a species of acroporid coral found in Australia, the Red Sea, the central Indo-Pacific, Japan, the northern Indian Ocean, the East China Sea, southeast Asia, and the western Pacific Ocean. It is particularly susceptible to coral bleaching, the crown-of-thorns sea star (Acanthaster planci), and harvesting for the aquarium trade. It is found on shallow coral reefs from depths of 5–20 m. It was described by Verrill in 1864.

Giant sea stars have a dense body with wide arms. Its surface is either tan or brown, but on occasion the giant sea star can have a yellowish or grayish surface. They contain thick, blunt spines that are bluish in color with white, pink or purple tips that are swollen and surrounded by brown fuzz and pedicellariae that have a plier like shape. These pedicellariae are used as a protective mechanism against predators.

Everton orders Steve to help a fellow crewman, Squeaky (Julio Oscar Mechoso), restore power to the ship. Immediately afterward, the ship's anchor drops on its own, sinking Sea Star with deckhand Hiko (Cliff Curtis) and first mate J.W. Woods, Jr. (Marshall Bell) on board. Steve leaves Squeaky to guard the engine room, where he is lured to his death by a robotic, spider-like creature. Steve rescues an injured Hiko, while Woods comes out unscathed.

This type of sea star grows five arms and can reach up to in length, though most stay around . The size is found to vary with depth, larger sea stars are found deeper while smaller ones are usually found in shallow waters. The can be found in a variety of colors, mainly white and brownish, but also can be an orange-red color. All sea stars have tube feet that are controlled by hydraulic pressure.
|

The pink sea star is a carnivore and scavenger. Its main prey is bivalves. It hunts, captures, and eats cockles, including Nuttall's cockle, butter clams, jackknife clams, horse clams, littleneck clams, and geoduck clams. How it locates buried clams in unknown, but once it finds a buried clam it will dig down to it by using its tube feet to push bits of sediment from near its mouth to the ends of its arms.
|
|
The margins of the arms are fringed with short white spines. The oral or underside of the sea star has further small white spiny plates down the edges of the arms and a central band of translucent, orange tube feet. Like other members of its genus, it has tube feet without suckers. The mouth is at the centre of the disc and there is no anus, undigested food fragments being expelled through the mouth.

In late December 2019, the Wildlife Conservation Society of India launched an expedition to Angria Bank, discovering a coral reef that hadn't bleached yet. The government of India plans to designate Angria Bank as a marine protected reserve. Angria Bank is known to have at least one laced moray eel, a school of schooling bannerfish, and a red knob sea star. Several common dolphins and Indo-Pacific bottlenose dolphins inhabit the deeper waters of the coast.

The ferry service resumed in October 2016 using the vessel Sea Star. In August 2017, the ferry service was suspended again to allow for further construction works at Lucky Bay harbour. In 2019, SeaSA advised that their vessel, the Aurora V which had been sold to a Venezuelan then bought back again, was stuck in Venezuela due to problems arising from political instability there. As of March 2020, the ferry service is not running but is expected to return.

Sea Star's crew, led by navigator and ex-Navy officer Kelly Foster (Jamie Lee Curtis) and engineer Steve Baker (William Baldwin), discover the engine room taking on water. When Sea Star takes refuge in the eye of the storm to make repairs, Volkov appears on their radar. Realizing that it could be worth millions in salvage, Everton orders his crew aboard. On Volkov, most of the electronics have been destroyed and the Russian crew are seemingly missing.

Mithrodia bradleyi in the Gulf of California Bradley's sea star has five arms that are banded in lighter and darker shades of red or red-brown. The disk is small. The arms are covered with many small bumps and fewer, more prominent spines. The spines are arranged in rows, including a row that runs right along the top of each arm, and typically two more rows that run the length of the arms on either side.
|
|
The central ring canal, in addition to connecting the radial canals to each other and to the stone canal, also has a number of other specialised structures on the inner surface. In between each radial canal, in many sea star species, there lies a muscular sac called a polian vesicle. The ring canal also has four or five pairs of complex pouches, called Tiedemann's bodies. These apparently produce coelomocytes, amoeboid cells somewhat similar to the blood cells of vertebrates.

Sea star Pine plantation on Great Palm Island Great Palm Island's rich volcanic soil supports tropical flora such as mangroves, eucalypt forest, rainforests, hoop pine, mango, banana, pawpaw (papaya) and wild plum trees. The surrounding bays have diverse marine fauna, including coral trout, crayfish and coral reefs. However the island has been affected by human settlement and introduced species. There are hundreds of brumbies (feral horses) on the island, considered to be owned by the community.

Misty features the annual Pony Penning of feral horses from Assateague Island, a two-day round-up, swim, and auction that Henry had been "sent to look at" by a hopeful editor. She created several Misty sequels including two more children's novels illustrated by Dennis, Sea Star, Orphan of Chincoteague (1949) and Stormy, Misty's Foal (1963). The beneficiaries of "Marguerite Henry's Legacy", as a Washington Post editorial termed local tourism, were the Assateague nature preserve and Chincoteague town."Marguerite Henry's Legacy".

Cananga odorata illustrated in Francisco Manuel Blanco's Flora de Filipinas Cananga odorata is a fast-growing tree of the custard apple family Annonaceae. Its growth exceeds per year, and it attains an average height of in an ideal climate. The evergreen leaves are smooth and glossy, oval, pointed and with wavy margins, and long. The flower is drooping, long-stalked, with six narrow, greenish-yellow (rarely pink) petals, rather like a sea star in appearance, and yields a highly fragrant essential oil.

Some sea stars prey on sea urchins, mussels, and other shellfish that have no other natural predators. If the sea star is removed from the ecosystem, the mussel population explodes uncontrollably, driving out most other species. Sea otters limit the damage sea urchins inflict on kelp forests. When the sea otters of the North American west coast were hunted commercially for their fur, their numbers fell to such low levels that they were unable to control the sea urchin population.

|
The seaweed and surf grass are able to grow farther up the tidal zones. Many sea stars have adapted to hide under the seaweed and surf, as a way to not dry out. This than allows them to feed on the various higher tidal zone organisms during high tide. The main diet of the Sea Star in Northern California is Mussels Since Davenport Tide Pools has an abundance of Mussels, Sea Stars do not resort to consuming other less desirable organisms.

The following year he starred in the box- office hits Tesis sobre un homicidio (Thesis on a Homicide) and 7th Floor (Séptimo). In 2013 he returned to theater and starred in the play Escenas de la vida conyugal (a Spanish adaptation of Ingmar Bergman's Scenes from a Marriage), alongside Valeria Bertuccelli. In 2015 he reprised the role with Érica Rivas, in Mar del Plata. His performance earned him the Sea Star (Estrella de Mar) Award for Best Actor in a Dramatic Comedy.

Sea star regenerating legs Woody material, often referred to as coarse woody debris, decays relatively slowly in many forests in comparison to most other organic materials, due to a combination of environmental factors and wood chemistry (see lignin). Trees growing in arid and/or cold environments do so especially slowly. Thus, tree trunks and branches can remain on the forest floor for long periods, affecting such things as wildlife habitat, fire behavior, and tree regeneration processes. Some trees leave behind eerie skeletons after death.

Some animals from the New England Seamounts: gorgonian soft coral, a brisingid sea star, and sponges The seamount chain provides a unique habitat for deep sea marine creatures. Coral formations grow on the rocky outcrops, resembling underwater forests that provide shelter for invertebrates and fish. Due to the expense and difficulties of studying the deep ocean, little was known of the creatures that inhabited the New England Seamounts. In fact, before recent expeditions, there was only one known coral species in the entire chain.

A predator to coral reefs in the Great Barrier Reef, the Crown of Thorns sea star, has experienced a similar death rate to the coral on which it feeds. Any increase in nutrients, possibly from river run-off, can positively affect the Crown of Thorns and lead to further destruction of the coral. Coralline algae holds together some coral reefs and is present in multiple ecosystems. As ocean acidification intensifies, however, it will not respond well and could damage the viability and structural integrity of coral reefs.

During this period Jesus met a priest by the name of Father Ge Chentung after travelling through many parts of the countryside and eventually arriving in Macau. Whilst he was in Macau, he witnessed the economic depression and saw the impact it had on the innumerable impoverished families of the region. He then decided to build a school similar to the one in Macau and manage its operations. He named it the Sea Star Middle school, it was located in one of the main streets of Macau.

The dogwinkle is itself eaten by the purple sea star (Pisaster ochraceus) and the red rock crab (Cancer productus). It lays its eggs in clusters of stalked capsules, known as "sea oats", which are attached to rocks high up in the intertidal zone. Although there are around 550 eggs in each capsule, most of the eggs are infertile and are consumed by the developing juveniles, 10 to 20 of which hatch from the capsule after three or four months, without an intermediate larval stage.

721-724 As shown the Davenport Tide Pool's rifts and ridges allow the Sea Star to reach limpets and snails in high tidal zones. This is a very prominent geographical feature at the Davenport Tide Pools since one would not normally see sea stars so high up the beach. The tide pools also have multiple sea caves and a smaller rock formation that is reminiscent of the bridges Natural Bridges State Beach. The last prominent geological feature is the high cliffs above the tide pools.

Many species of Periclimenes are commensal and often symbiotic organisms within their reef ecosystems. The most common organisms forming symbiotic relationships with this genus are species of fish, cnidarians, echinoderms, and sponges. Some species such as Periclimenes caraibicus have been observed to interact parasitically with species of sponges, living within the sponge and directly eating the sponge tissue. Another species, Periclimenes soror, is commonly found on a species of sea star known as cushion stars with no affect on the star making it a commensalistic relationship.

The bat star (Patiria miniata), also known as a sea bat, webbed star, and broad-disk star, is a species of sea star (also called a starfish) in the family Asterinidae. It typically has five arms, with the center disk of the animal being much wider than the stubby arms are in length. Although the bat star usually has five arms, it sometimes has as many as nine. Bat stars occur in many colors, including green, purple, red, orange, yellow and brown, either mottled or solid.

The common starfish, common sea star or sugar starfish (Asterias rubens) is the most common and familiar starfish in the north-east Atlantic. Belonging to the family Asteriidae, it has five arms and usually grows to between 10-30 cm across, although larger specimens (up to 52 cm across) are known. The common starfish is usually orange or brownish in color, and sometimes violet; specimens found in deeper waters are pale. The common starfish is found on rocky and gravelly substrates where it feeds on mollusks and other benthic invertebrates.

The miniseries followed the vessels F/V Northwestern, Erla-N and Sea Star during king crab, and Erla-N, Saga and Arctic Dawn during opilio crab. The series also features several crises, including the half-capsized Raven (5 on board, all rescued alive), man- overboard calls from Shaman (recovered dead) and Saga (greenhorn Kevin Davis, rescued alive), and the constant threat of cold water and freezing spray. Beers did the voice-over narration for both series. Discovery picked up the show and ordered an 8-episode season to premiere in 2005.

The study also found that the sea star consumes the mollusk shell regardless of whether or not the original organism is still inside. The fact that the scientists found parts of A. articulatus in their own stomachs means that they can be considered as cannibals, which is also the case for their relative A. irregularis. An investigation of three digestive enzymes in the stomachs of A. articulatus give more information about its feeding. The study measured enzyme activity of the enzymes chymotrypsin, -glucosidase, and -glucosidase on subtropical and polar echinoderms.
|
|
In the same study, A. articulatus was also given a choice of small sized prey and larger sized prey. The A. articulatus chose to consume the smaller sized prey more often, and this is because smaller prey decreases handling time. This means that the sea star prefers to consume the organism that would provide it with the most net energy gain for the shortest time, and therefore forages optimally. The scientists also found that the A. articulatus exhibit directional movement when prey is not present in its surroundings.

P. prolifica is an opportunistic feeder, being a deposit feeder or a suspension feeder depending on circumstances. It can reproduce asexually by dividing to form new individuals, or can breed sexually by shedding sperm and eggs into the sea. The dense colonies of branching tubes of this worm provide a habitat with an abundance of food and low risk of predation for the juveniles of some species of starfish. Researchers in Washington state found that the larvae of the vermillion sea star (Mediaster aequalis) preferentially settled on the tubes.

These may impact both on starfish and on echinoderm populations in general, and a ciliate protozoan parasite (Orchitophrya stellarum) of starfish, which eats sperm and effectively emasculates male starfish, thrives at higher temperatures. However, temperature was not related to the initial outbreak of sea star wasting disease at many places along the coast. Unlike with many other wildlife diseases, there was no link between the density of sea stars at a location before disease outbreak and the severity of population decline. Thus, this outbreak has defied prediction using what is typically understood about disease spread.

In the book this is the last we hear of Sophie, and it is presumed she makes it back to Alaska. However in the 1967 film, Dolittle is tried and found guilty of insanity by General Bellowes, who commits him to an insane asylum. The animals catch wind of it and help Dolittle hightail it out of town before he can be incarcerated, embarking upon a series of worldwide adventures on the open sea. When Sophie catches up to him again, he is ensconced upon Sea Star Island.

In Lofting's original books, the Giant Moth named Jamaro Bumblelily makes the arduous trip between Earth and the Moon in Doctor Dolittle's Garden and Doctor Dolittle in the Moon. In the 1967 film, the Giant Lunar Moth travels regularly back and forth between Earth and the Moon. When Doctor Dolittle gets good news from England that the animals have gone on strike and General Bellows has decided to pardon Doctor Dolittle, he ends his exile on Sea Star Island by persuading the moth to make a slight detour and drop him off in Puddleby.

Storm Watch features special effect scenes reused from the films Virus, End of Days, and Set It Off. Clips from Virus include the alien energy hitting the Russian ship (in Storm Watch, it is lightning hitting a decommissioned ship the Army uses for a target); and the "Sea Star" tug boat caught in the storm (shot to be a natural storm, in this film it is artificial). The entire subway train miniature exteriors are from End of Days. The Chevrolet Impala car chase was lifted from Set It Off.

Madreporite of Asterias In sea stars, water enters the system through a sieve-like structure on the upper surface of the animal, called the madreporite. This overlies a small sac, or ampulla, connected to a duct termed the stone canal, which is, as its name implies, commonly lined with calcareous material. The stone canal runs to a circular ring canal, from which radial canals run outwards along the ambulacral grooves. Each arm of a sea star has one such groove on its underside, while, in sea urchins, they run along the outside of the body.

The first permanent European settlers of the Southern California Bight, led by Juan Pérez, arrived in 1769 on the San Antonio. The Spanish government had planned a three-part occupation plan to check the Russians’ settlement in Alta California. In 2013-14, scientists witnessed the largest die-off of sea stars ever recorded along the Pacific Coast. The outbreak of sea star wasting disease caused significant changes to the ecosystem as sea stars are a keystone species that plays an important role in controlling the numbers of other creatures.

Benthic suspension feeders, such as bivalves, can exert considerable grazing pressure on phytoplankton and microzooplankton. Thus, benthic and pelagic fauna can act as habitat couplers by consuming resources originating from either the water column or the sediment. On rocky intertidal shores, the effects of nearshore currents on phytoplankton and sea star propagules influence the benthic community structure of mussels and predation pressure by sea stars. Detritivores inhabiting benthic areas derive energy from sinking pelagic detritus and are then consumed by either benthic or pelagic predators, impacting community structure.

The nine-armed sea star is a scavenger and a predator and examination of the stomach contents show that the diet consists primarily of molluscs, small crustaceans and polychaete worms. Many of the food items were swallowed whole and had been ingested by the starfish everting its stomach and engulfing its prey. It also buries itself in the substrate and engulfs "mouthfuls" of sediment, filtering it through its oral spines and extracting detritus and small organisms such as brittle stars. Breeding takes place at different times of the year in different parts of the range.

Pacific Rim National Park Reserve is a park located in British Columbia, Canada, which comprises three separate regions: Long Beach, the Broken Group Islands, and the West Coast Trail. It represents the Pacific Coast Mountains landscape, which is characterized by rugged coasts and temperate rainforests. Widespread vegetation found in the park includes western hemlock, Sitka spruce, western red-cedar, deer fern and sword fern. Animal species vary from marine and intertidal species, such as humpback whales and ochre sea star, to terrestrial mammals, such as Vancouver Island wolves.

Through October 2005, near the end of Northern Lights chartered service, the vessel made 25 voyages and 49 port calls. Collectively, 12,200 pieces of military equipment—weighing in all—were transported by the ship. Robert Magee, then president of TOTE, and the crew of Northern Lights were praised by United States Air Force general Norton A. Schwartz: "You and your team of professionals showcased the US flag industry at its best." Following completion of her military services in 2006, the ship was transferred by TOTE to its subsidiary company Sea Star Lines and renamed El Faro.

A. articulatus feeds by swallowing its food whole and digesting it in its stomach, like other members of the genus Astropecten. However, unlike other species in the same genus, A. articulatus consumes significantly more organisms. In a study investigating the stomach contents of 124 A. articulatus sea stars, scientists found that on average, each sea star has 12 organisms in its stomach, with the highest number of organisms recorded being 54. When comparing the number of organisms in the A. articulatus stomachs to another study investigating the stomach contents of A. auranciacus, it is revealed that the A. articulatus have much higher amounts.
|
|
Also, one study investigating A. irregularis shows the same outcome, that there are more organisms in the stomachs of A. articulatus than A. irregularis, but in another study, the stomachs of both sea star species are relatively the same. A. articulatus also feeds on a diverse number of organisms. From the previous study, in all of the 124 sea stars combined, there were a total of 91 species of organisms found in their stomachs. The three most abundant species were A. candei, N. pusila, and O. mutica, which were gastropods, and accounted for 60% of all species that A. articulatus feed on.

The program concept was developed by Terebi Doga, (a.k.a. Japan Tele-Cartoons or JTC), in Japan in 1965, originally known as Dolphin Prince (ドルフィン王子 - Dorufin Ôji). Produced as a short experimental trial series of only three episodes and filmed in black and white, Dolphin Prince aired on Fuji TV on Sundays at 7:30 pm between 4 April and 18 April 1965. The episodes featured young Dolphin Prince, his mermaid friend Neptuna and Dr. Mariner, with stories entitled "Secret Of The Red Vortex", "Call Of The Sea" and "Attack Of The Sea- Star People".

Predators of Semibalanus balanoides include the whelk Nucella lapillus, the shanny Lipophrys pholis, the sea star Asterias vulgaris, and nudibranchs. Although they have no eyes, barnacles are aware of changes in light, and withdraw into their shells when threatened. Parasites of S. balanus include Pyxinoides balani, a protozoan which lives in the barnacle's midgut, and Epistylis horizontalis, a ciliate which lives on the gills. The isopod Hemioniscus balani occurs from France to the Faroe Islands and the Oslofjord, and from Labrador to Massachusetts, and is a parasite of S. balanoides, effectively castrating the barnacle if it is heavily infested.

However, the core sequence of RAG1 has been identified in the echinoderm Strongylocentrotus purpuratus (purple sea urchin), the amphioxi Branchiostoma floridae (Florida lancelet). Sequences with homology to RAG1 have also been identified in Lytechinus veriegatus (green sea urchin), Patiria minata (sea star), and the mollusk Aplysia californica. These findings indicate that the Transib family transposon invaded multiple times in non-vertebrate species, and invaded the ancestral jawed vertebrate genome about 500 MYA. It is currently hypothesized that the invasion of RAG1/2 is the most important evolutionary event in terms of shaping the gnathostome adaptive immune system vs.

This enormous undersea mollusk with a transparent airtight shell is injured when the mysterious floating Spider Monkey Island finally comes to rest in The Voyages of Doctor Dolittle. The animals arrange for him to ferry Dr. Dolittle and his party back through the ocean to Puddleby. In the 1967 film, Dolittle resigns himself to living abroad for the rest of his life due to the price on his head issued by General Bellowes. The [renamed] Great Pink Sea Snail takes Matthew, Tommy, Emma and a host of small animals from the [renamed] Sea Star Island back to England.

Pi and Dylan find their way home, where Pearl (Fran Drescher) is excited to see that Pi has arrived. She is a fortune teller along with her assistant Madge, a sea star and uses a pink pearl that Dylan's deceased father gave to her as a crystal ball. Pearl reads Pi's future and is surprised, saying that he is destined for great things and that the reef is the best place he will be able to find it. Pearl then tells Pi that he can go anywhere on the reef excluding an old pirate wreck and a forbidden place called "flat bottom".

Although it is toxic to many vertebrates, some fish have been observed to feed on this sponge, a fact confirmed by fragments of the sponge being found in their guts; these fish include the queen angelfish (Holacanthus ciliaris), the rock beauty (Holacanthus tricolor) and the French angelfish (Pomacanthus paru). Other predators feeding on the sponge include the polychaete worm Branchiosyllis oculata, and the red cushion sea star (Oreaster reticulatus). It is also preyed upon by the hawksbill sea turtle (Eretmochelys imbricata). The tunnels and cavities inside the sponge are home to a wide array of invertebrates.

It is sometimes reported that the lurid rocksnail is in fact the gumboot chiton's only predator, but others list such animals as the sea star Pisaster ochraceus, some octopus species, and the sea otter. Several other animal species have been observed living within the gumboot's gills; the relationship is thought to be commensal: neither harmful nor helpful to the chiton. One researcher found that more than a quarter of gumboots hosted an Arctonoe vittata, a pale yellow scale worm which can grow up to length. Opisthopus transversus, a small crab, is also sometimes found within the gills.

Some scallops, including Chlamys hastata, frequently carry epibionts such as sponges and barnacles on their shells. The relationship of the sponge to the scallop is characterized as a form of mutualism, because the sponge provides protection by interfering with adhesion of predatory sea-star tube feet, camouflages Chlamys hastata from predators, or forms a physical barrier around byssal openings to prevent sea stars from inserting their digestive membranes. Sponge encrustation protects C. hastata from barnacle larvae settlement, serving as a protection from epibionts that increase susceptibility to predators. Thus, barnacle larvae settlement occurs more frequently on sponge-free shells than sponge- encrusted shells.

Thus, Species A indirectly benefits Species C. Pathways of indirect interactions can include all other forms of species interactions. To follow the sea star-mussel relationship, sea stars have an indirect negative effect on the diverse community that lives in the mussel bed because, by preying on mussels and decreasing mussel bed structure, those species that are facilitated by mussels are left homeless. Additional important species interactions include mutualism, which is seen in symbioses between sea anemones and their internal symbiotic algae, and parasitism, which is prevalent but is only beginning to be appreciated for its effects on community structure.

Changes in ocean current systems and local thermal environments has shifted many tropical species range Northward while temperate species have lost their Southern limits. Large range shifts along with outbreaks of toxic algal blooms has impacted many species across taxa. Management of these affected species becomes increasingly difficult as they migrate across management boundaries and the food web dynamics shift. A decline in species abundance such as the mass mortality of 25 benthic species in the Mediterranean in 2003, the Sea Star Wasting Disease, and coral bleaching events have been linked to increase in sea surface temperature.

If the prey is too large to be swallowed whole, then it can use its tube feet to open shells. It can evert its stomach through its mouth and engulf its prey, liquify it with digestive enzymes and ingest the processed food. Mussels hold their valves together very securely but P. ochraceus can insert part of its everted stomach, or some digestive juices, through the narrow gap that exists where the byssal threads emerge from the shell. The mussel needs to open its valves periodically to feed and breathe and the sea star can exert a powerful traction with its tube feet, pulling the two valves further open.

This sea star has very narrow and high superomarginal plates with a bare area on vertical face of them (visible in the lateral side of arms between inferomarginal spines and superomarginal spines). Every superomarginal plate is equipped with 1 very long, sharp, clean conical spine usually white colour but sometime yellow or orange. The superomarginal spine is always placed on the top internal edge of plates so there aren’t any bare area on top of superomarginal plates. The maximum number of superomarginal plates, observed on each arm, is 77; normally the number is between 40 and 60, depending on the size of the starfish.

In June 2007, the ship was sold to a Panamanian- registered company, Sea Star International Shipping Group Inc, and renamed New Legend Glory. The ship's most recent reported registered owner, Panamanian- registered Briarwood Corp, acquired the vessel in August 2008 and renamed it Rhosus. After lengthening the hull from to and converting the ship to a general cargo vessel, Rhosus was reflagged first to Georgia in 2009 and later to Moldova in 2012. By 2012, the vessel was effectively owned by Cypriot businessman Charalambos Manoli, who sold it that year to Khabarovsk-born Russian businessman Igor Grechushkin, who was reported to be living in Limassol, Cyprus, in 2020.

Aboral surface of an Asterias forbesi sea star showing ring of pedicellariae surrounding spine Asterias, like most starfish genera in the order Forcipulatida, are recognisable externally by their pedicellariae, many thousands of tiny jaw- like structures on the skin which can snap shut to nip at prey or predators. Asterias has two types present -the major, also called straight, pedicellaria, which lie scattered across their skin, and the smaller minor, also called crossed, pedicellaria, which are found in tufts or wreaths around the large dorsal spines -these pedicellariae have tiny, rubbery stalks known as pedicels. Papulae are also present. All species normally have five arms.

The shoreline's sand dune habitat consists of pink and yellow sand-verbena, dune grass, seaside centipede lichen, black oystercatchers, and glaucous-winged gulls. The intertidal zone provides habitat for eelgrass, Aggregating anemone, echinoderms (like the western sand dollar and ochre sea star), sea snails (like the northern abalone), and crabs. Native bivalvia like butter clam, littleneck clam, California mussel and Olympia oyster compete with the invasive Manila clam, varnish clam, and Pacific oyster. The park also includes a subtidal area where there exists several kelp forests, habitat for Steller sea lions, seals and porpoises, and parts of migratory routes for killer whales, humpback whales, grey whales, basking sharks, and pacific herring.

In February 2008, Sig Hansen and Liquid Dragon Studios announced the upcoming release of a video game for Xbox 360 and PC inspired by the Deadliest Catch series entitled Deadliest Catch: Alaskan Storm. Liquid Dragon designers spent time with the Hansens on the F/V Northwestern in the safety of Dutch Harbor and out on the Bering Sea to give them a sense of the real conditions that needed to be duplicated in the game. The game itself features the F/V Northwestern, Cornelia Marie, and Sea Star as crab boats that can be chosen by the player, along with the Bering Star and the Shellfish. On June 17, 2008, the game was released in stores around North America.

This has a considerable impact on the microhabitat and may be beneficial for the urchin as it results in an increase in the growth of the algae and bacteria forming the film round the particles of sediment. The red heart urchin has few predators but is sometimes preyed on by stingrays and other fish, loggerhead turtles and the sea star Oreaster reticulatus. It can emit a noxious yellow exudate which repels fish and may even kill them. Several red heart urchins may aggregate and the progress of each one through the sediment can be observed by a depressed trail left behind as it progresses and a slight mound of coarser material above it.

Beachcast D. antarctica kelp frond with blisters caused by an infection Holdfasts of D. antarctica and other species are often inhabited by a diverse array of epifaunal invertebrates, many of which burrow into and graze on the kelp. In New Zealand, epifaunal species include the sea-star Anasterias suteri, crustaceans Parawaldeckia kidderi, P. karaka, Limnoria segnis and L. stephenseni, and the molluscs Cantharidus roseus, Onchidella marginata, Onithochiton neglectus, and Sypharochiton sinclairi. Beachcast D. antarctica at St Kilda Beach, Dunedin Specimens of Durvillaea can detach from substrates, particularly during storms. Once detached, buoyant species such as D. antarctica and D. poha can float as rafts, and can travel vast distances at sea, driven by ocean currents.

Underwater in McMurdo Sound with an ice wall behind and many Antarctic scallops, several sea urchins, Sterechinus neumayeri and brittle stars, Ophionotus victoriae, and a white club-shaped sponge, Homaxinella balfourensis The Antarctic scallop is monitored in connection with the Vulnerable Marine Ecosystems (VME) classification set up by the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR). As such, notification is required to be made by vessels that land the scallop as by- catch during their fishing activities. The Antarctic scallop is often found living in association with the Antarctic sea urchin, Sterechinus neumayeri, and Odontaster validus, a species of sea star. Predatory invertebrates found in the vicinity of the Antarctic scallop include the gastropod Neobuccinum eatoni, and the ribbon worm Parborlasia corrugatus.

There is a positive correlation between temperature and calcite saturation state for the eastern oyster Crassostrea virginica, which produces a shell primarily composed of calcite. While oysters are benthic and use calcite instead of aragonite (like pteropods), there is still a clear increase in both calcite saturation level and oyster calcification rate at the higher temperature treatments. A bed of Crassostrea virginica on Cockspur Island, Georgia In addition to impacting the solubility and saturation state of calcite and aragonite, temperature can alter the composition of shell or calcified skeletons, especially influencing the incorporation of magnesium (Mg) into the mineral matrix. Magnesium content of carbonate skeletons (as MgCO3) increases with temperature, explaining a third of the variation in sea star Mg:Ca ratios.

Around 1973, the entertainment activities in Mar del Plata’ summer, such as theatrical plays, the so-called café-concerts, circus and recitals reached a degree of development that made it one of the most profitable investments of the summer season. The Municipal Agency of Tourism took account of the situation, and established the awards, namely the Estrella de Mar (Sea Star), in order to promote the quality of the spectacles and to attract the interest of entrepreneurs. Although the mainstream stage was in the hands of national- level actors and producers, the contest is a genuine local product. The following two decades consolidated the prestige of the awards, and the producers and directors see the Estrella the Mar as a formidable publicity for their works and careers.

Aquilonastra burtoni is a small species of sea star with up to 8 rays, frequently 7, they frequently demonstrate an asymmetrical form after fissiparous division while the form of larger specimens is often symmetrical with 5 equal rays; there is an inconspicuous madreporite in most interradii. The rays narrow basally, tapering to a narrow rounded distal part which is finger-like. Each of the plates on the oral surface has a grouping of 3 crowded mobile tapering spines in their centres, while those of the dorsal surface have a dense group of short tubercles. It is a greenish gray colour on the dorsal sid with a large, irregular, purplish brown blotch in the centre which is surrounded by red spots at the bases of the arms.

As the commander of the Frisian Fleet, Lieutenant-Admiral Tjerk Hiddes de Vries, had been killed also, Star functioned as acting lieutenant-admiral until the appointment of Lieutenant-Admiral Hans Willem van Aylva on 16 March 1667. Star in 1667 participated in the Raid on the Medway, in the later phases of the campaign commanding a squadron blockading Harwich, using as flagship the Groningen of seventy cannon. In 1672, during the Franco-Dutch War, Baron van Aylva became an Infantry General and would never return to sea. Star thus again functioned as acting commander of the Frisian Fleet during the Third Anglo-Dutch War, fighting in 1672 during the Battle of Solebay and in 1673 during the Battles of Schooneveld and the Battle of the Texel, still on the Groningen.

The star figures in many of the titles of Mary, including La Madonna della Stella, Star of the New Evangelization, Star of the Sea, Star of Jacob, Morning Star, and Fixed Star, to name a few. The crown of stars depicted in the Queen of Angels Foundation logo is a Crown of Immortality, reflecting the Catholic teaching of Queenship of Mary. That there are seven stars above her crown also call to mind the key role Mary played in Salvation History. The seven stars on the Crown of Immortality of Our Lady of the Angels also signify the Seven Corporal Works of Mercy as well as the Seven Spiritual Works of Mercy, the Seven Gifts of the Holy Spirit, the Seven Virtues, the Seven Joys of Mary and the Seven Sorrows of Mary.

A marine heatwave (MHW) is a short period of abnormally high temperatures in a sea or ocean. Marine heatwaves are caused by a variety of factors and have been associated with severe biodiversity changes such as sea star wasting disease, toxic algal blooms, and mass mortality of benthic communities. Major marine heatwave events such as Great Barrier Reef 2002, Mediterranean 2003, Northwest Atlantic 2012, and Northeast Pacific 2013-2016 have had drastic and long-term impacts on the oceanographic and biological conditions in those areas. The Intergovernmental Panel on Climate Change (IPCC) report on Global Warming of 1.5 °C is "virtually certain" that the global ocean has absorbed more than 90% of the excess heat in our climate systems, the rate of ocean warming has doubled, and MHW events have doubled in frequency since 1982.

A study in 2008 examining a sediment core from the North Atlantic found that while the species composition of coccolithophorids has remained unchanged for the industrial period 1780 to 2004, the calcification of coccoliths has increased by up to 40% during the same time. A 2010 study from Stony Brook University suggested that while some areas are overharvested and other fishing grounds are being restored, because of ocean acidification it may be impossible to bring back many previous shellfish populations. While the full ecological consequences of these changes in calcification are still uncertain, it appears likely that many calcifying species will be adversely affected. When exposed in experiments to pH reduced by 0.2 to 0.4, larvae of a temperate brittlestar, a relative of the common sea star, fewer than 0.1 percent survived more than eight days.

McClintock discovered his professional passion while growing up along the Pacific Ocean in Santa Barbara, CA. His initial research focused on echinoderm (primarily sea star and sea urchin) nutrition, and reproduction in both the Pacific and Atlantic oceans. In 1982 he made his first scientific foray into the chilly Indian Ocean as a participant in the French Antarctic Research Program working at a research base on the sub- Antarctic island of Kerguelen. The following two years, as a National Science Foundation Postdoctoral Fellow, McClintock continued his echinoderm studies in the freezing waters of Antarctica's Southern Ocean at the United States research station McMurdo Station. Since 1989 McClintock has led or co-directed fourteen scientific expeditions with the United States Antarctic Program (USAP) in which he and his research collaborators have become the world’s authorities on Antarctic marine chemical ecology.

A red knob sea star, right Echinoderms differ from chordates and their other relatives in three conspicuous ways: they possess bilateral symmetry only as larvae - in adulthood they have radial symmetry, meaning that their body pattern is shaped like a wheel; they have tube feet; and their bodies are supported by skeletons made of calcite, a material not used by chordates. Their hard, calcified shells keep their bodies well protected from the environment, and these skeletons enclose their bodies, but are also covered by thin skins. The feet are powered by another unique feature of echinoderms, a water vascular system of canals that also functions as a "lung" and surrounded by muscles that act as pumps. Crinoids look rather like flowers, and use their feather-like arms to filter food particles out of the water; most live anchored to rocks, but a few can move very slowly.

His interest in the live interplay of image and music has led him to experiment and create with Soundbeam, an ultrasonic series of beams that act as invisible keyboards in space. With each beam containing up to 128 invisible divisions, each division can become the start and stop button to turn on and project a video sequence, a sequence of a stills or trigger a sequence or note of music. His work, in conjunction with The Soundbeam Project, led to the creation of Inua, a live performance piece which won 2004 Composer of the Year (Community and Education) from the British Academy of Composers and Songwriters. As well as his film and television work, Kiszko's major concert works include two cantatas: Sea Star with a libretto by poet Anne Ridler OBE, and A Radius of Curves – a work with his own libretto and accompanying film – which tells the story of the construction of Brunel's Great Western Railway.

Tomie's main ability is a form of regeneration similar to that of a sea star or a planarian if a part of her body, such as an arm, leg or even head is severed, an entire clone of her body will grow from the severed part. This will occur even with smaller parts, such as fingers, or even blood. The one exception to this rule seems to be Tomie's hair, which will instead attach itself to the body of another person and slowly burrow into their body and multiply, eventually killing the victim by piercing a vital organ or literally causing them to explode with cloned Tomie- hair, as seen in the chapter Hair from the second volume. In some works, it is implied that burning the body of a Tomie clone will kill her permanently, while in others, she regenerates from the ashes, though this could be because she was not completely burned.
