Gurney's two great study objects were the Copepoda and the larvae of Decapoda, and his greatest works were the three-volume monograph British Freshwater Copepoda, published by the Ray Society in 1931–1933, and his Larvae of Decapod Crustacea published by the Ray Society in 1942. Perhaps through the influence of Garstang, Gurney rejected Ernst Haeckel's biogenetic law (that "ontogeny recapitulates phylogeny"), preferring Garstang's concept of paedomorphosis as an explanation for the similarities between copepods and decapod larvae. Gurney was, however, very tentative in his speculations.

Nectonematids spend the larval stage of their life cycle as parasites of decapod crustaceans. At least 28 host species have been identified, including hermit crabs, crabs, caridean shrimp and Eusergestes prawns; a single N. agile individual has also been found within an American lobster (Homarus americanus) specimen. Larvae inhabit hosts' body cavity, especially in the region of the thorax; typically, a decapod will be host to a single nectonematid, however as many as nine have been observed inhabiting a single crab. Evidence is conflicting on possible correlations between the size and sex of hosts and nectonematid infection rates and growth sizes.

Some examples of pelagic invertebrates include krill, copepods, jellyfish, decapod larvae, hyperiid amphipods, rotifers and cladocerans. Thorson's rule states that benthic marine invertebrates at low latitudes tend to produce large numbers of eggs developing to widely dispersing pelagic larvae, whereas at high latitudes such organisms tend to produce fewer and larger lecithotrophic (yolk-feeding) eggs and larger offspring.

The five marine species of nematomorph are contained in Nectonematoida.Pechenik, 'Biology of the Invertebrates, 2010, pg 457. Adults are planktonic and the larvae parasitise decapod crustaceans, especially crabs. They are characterized by a double row of natotory setae along each side of the body, dorsal and ventral longitudinal epidermal cords, a spacious and fluid-filled blastocoelom and singular gonads.

The species in this family are heteroxenous, meaning they live in two separate hosts during their life cycle. The two host species involved in their life cycle are a crustacean and a mollusc. The life cycle involves vegetative development in digestive tract of a decapod crustacean and sporogony in the connective tissue of a lamellibranch mollusc.

Hippidae is a family of decapod crustaceans, commonly known as "mole crabs" or "sand crabs". They are closely related to the family Albuneidae, with which they are usually joined in the superfamily Hippoidea. The family Hippidae comprises the three genera Emerita, Hippa and Mastigochirus. They burrow into sand, and are found throughout the world, except the Arctic and Antarctic.

Leptogorgia virgulata sometimes grows in meadows of the seagrass Thalassia testudinum where it is often associated with the amphipod Caprella penantis. In winter, when the seagrass dies down, decapod crustaceans move into the area. The oyster Pteria colymbus is often found attached to the coral. Other animals are camouflaged to resemble the coral in shape or colour.

Specimens of D. nahuelbutaensis from fast-flowing, moderate- elevation (370-520 m) tributaries of the Bío Bío River had eaten aquatic insect larvae, especially chironomids, and the relatively large decapod crustacean Aegla. Reproduction occurs at least during the austral summer based on captures of females with maturing eggs, and the juveniles reported here were collected in December.

This class of locomotive was later the inspiration of the Reverend Awdry's Toby the tram engine. Finally mention must be made of the Decapod which was the first built in Britain, and possibly the only locomotive built for purely political purposes in order to block the passage through Parliament of a new rival scheme for an electric railway.

Decapod locomotive, numbered as E1060 by Japanese occupation. Currently operated by West Sumatra Division of Indonesian Railway Company in Sawahlunto, West Sumatra. The Staatspoorwegen ter Sumatara's Westkust (SSS) built a railway line on the west coast of Sumatra from 1887 until 1896. This railway used to haul products from Ombilin coal mines to the port of Teluk Bayur in Padang.

The Lickey Banker Only two 0-10-0 locomotives saw service on British railways. One was a suburban tank locomotive prototype, built by James Holden for the Great Eastern Railway in 1902 and called the Decapod. The other was a tender locomotive, no. 2290, built by the Midland Railway in 1919, specifically for use as a banker for the Lickey Incline.

Percnon gibbesi is a species of crab. It is one of at least two species commonly called "Sally Lightfoot" (the other being the semi-terrestrial Grapsus grapsus from the Pacific coast of the Americas), and is also referred to as the nimble spray crab or urchin crab. It has been described as "the most invasive decapod species to enter the Mediterranean".

Callinectes sapidus is a decapod crab of the swimming crab family Portunidae. The genus Callinectes is distinguished from other portunid crabs by the lack of an internal spine on the carpus (the middle segment of the claw), as well as by the T-shape of the male abdomen. Blue crabs may grow to a carapace width of . C. sapidus individuals exhibit sexual dimorphism.

|
In the North Sea, off Britain, each female lays 2000–3000 eggs in November. When fertilised, she carries them around for a few days on her periopods. They then hatch and go through six zoeal and two to five decapod planktonic larval stages before undergoing metamorphosis and settling as juveniles. The rate of development of the larvae depends on the water temperature.

The marine crocodile Metriorhynchus, fish, decapod, mysid and thylacocephalan crustaceans, crinoids, ophiuroids (most commonly Ophiopinna elegans) are also to be found. The in situ mortality horizon consists of abundant pavements of the bivalve Bositra buchi and trace fossils of suspected worm burrows. Two specimens of plants suggest that a shoreline was not far distant, represented today by France's Massif Central.

Porcelain crabs are decapod crustaceans in the widespread family Porcellanidae, which superficially resemble true crabs. They have flattened bodies as an adaptation for living in rock crevices. They are delicate, readily losing limbs when attacked, and use their large claws for maintaining territories. They first appeared in the Tithonian age of the Late Jurassic epoch, 145-152 million years ago.

Aciculopoda is an extinct prawn which existed in what is now Oklahoma approximately . It was described in 2010 on the basis of a single fossil from Oklahoma. The single species, Aciculopoda mapesi, was named by Rodney Feldmann and Carrie Schweitzer in honour of Royal Mapes, a paleontologist who discovered the type specimen. It is only the third unambiguous fossil decapod from before the Mesozoic.

Mangatarere Stream is a small gravel-bed stream in central Wairarapa, New Zealand, that originates in the Tararua Ranges. It is located close to the township of Carterton and is the main tributary to the Waiohine River. The Waiohine flows into the Ruamahanga River, southeast of Greytown. Eleven species of native freshwater fish and one native decapod (koura) have been recorded within the Mangatarere Stream catchment.

The body of a decapod crustacean, such as a crab, lobster, or prawn (shrimp), is made up of twenty body segments grouped into two main body parts, the cephalothorax and the abdomen. Each segment may possess one pair of appendages, although in various groups, these may be reduced or missing. On average, crayfish grow to in length. Walking legs have a small claw at the end.

Thalassinoides is an ichnogenus of trace fossil used to refer to "dichotomously or T-branched boxworks, mazes and shafts, unlined and unornamented". Facies of Thalassinoides increased suddenly in abundance at the beginning of the Mesozoic. Such burrows are made by a number of organisms, including the sea anemone Cerianthus, Balanoglossus and fishes, but are most closely associated with decapod crustaceans of the (former) infraorder Thalassinidea.

Alcock was primarily a systematist, describing a wide range of species. He worked on aspects of biology and physiology of fishes, their distributions, evolution and behaviour. Some of his works were published in "Zoological Gleanings from the R.I.M.S. ' Investigator,' " published in " Scientific Memoirs by Medical Officers of the Army of India," Part XII, Simla, 1901. He worked on Fishes, Decapod Crustacea, and Deep Sea Madreporarian Corals.

The pink whipray feeds primarily on decapod crustaceans, but also takes cephalopods, and teleost fishes. In Shark Bay, penaeid prawns are by far the dominant prey type for rays of all sizes. At Rangiroa Atoll in French Polynesia, sizable feeding aggregations are known to form at night in shallow water. However, at Moorea it tends to be a solitary forager with a large home range.

Edward John Miers FZS FLS (1851– 15 October 1930) was a British zoologist and curator of the crustacean collection at the Natural History Museum in London. He contributed to the scientific reports from the Challenger expedition of 1872–1876, and described 32 new genera and at least 260 new species and subspecies of decapod crustaceans, along with four genera and 72 new species in other orders.

Parhippolyte is a genus of cave dwelling decapod crustaceans, known as cave shrimps from the family Barbouriidae The type species Parhipplyte uvea was described in 1900 by the English carcinologist Lancelot Alexander Borradaile from specimens collected in the south western Pacific by Arthur Willey. As their vernacular name of cave shrimp suggests these species are generally found in marine caves as well as anchialine ponds and lagoons.

Strasburg Rail Road (Great Western) No. 90 is a 2-10-0 "Decapod" type steam locomotive owned and operated by the Strasburg Rail Road outside of Strasburg, Pennsylvania. Built by the Baldwin Locomotive Works in 1924, 90 originally pulled sugar beet trains for the Great Western Railway of Colorado. In 1967, 90 was sold to the Strasburg Rail Road where it now resides and operates today for use on excursion trains.

The only unambiguous decapod fossil older than Aciculopoda is Palaeopalaemon newberryi, found in Devonian sediments in Ohio. (The assignment of Imocaris to the Decapoda is the subject of some debate.) The fact that both Aciculopoda and Palaeopalaemon were discovered in the United States led Feldmann & Schweitzer to suggest that their common ancestor, the most recent common ancestor of the Decapoda may also have originated in the ancient continent Laurentia.

The South West African 0-10-0 of 1911 was a steam locomotive from the German South West Africa era. In 1911, the Lüderitzbucht Eisenbahn (Lüderitzbucht Railway) in German South West Africa placed six locomotives with a Decapod type wheel arrangement in service. They were no longer in service when all railways in the territory came under the administration of the South African Railways in 1922.Espitalier, T.J.; Day, W.A.J. (1948).

Like other decapod crustaceans, the crayfish possesses a hard, segmented exoskeleton that reflects muscular and neural segmentation. The anterior portion of the crayfish is the cephalothorax region. The region rostral to the cephalic grove, which separates the head and thorax region, is characterized by the presence of eyes, antennae and claws while the region caudal contains four pairs of walking legs. This is the crayfish's primary mode of locomotion.

Sample of zooplankton which includes fish eggs, doliolids, several species of copepods, gastropod and decapod larva Zooplankton (, ) are heterotrophic (sometimes detritivorous) plankton (cf. phytoplankton). Plankton are organisms drifting in oceans, seas, and bodies of fresh water. The word zooplankton is derived from the Greek zoon (), meaning "animal", and ' (), meaning "wanderer" or "drifter". Individual zooplankton are usually microscopic, but some (such as jellyfish) are larger and visible to the naked eye.

A Pacific cleaner shrimp, Lysmata amboinensis, cleans the mouth of a moray eel. Periclimenes magnificusii, provides a manicure for a diver. Cleaner shrimp is a common name for a number of swimming decapod crustaceans, that clean other organisms of parasites. They belong to any of three families, Hippolytidae (including the Pacific cleaner shrimp, Lysmata amboinensis), Palaemonidae (including the spotted Periclimenes magnificus) , and Stenopodidae (including the banded coral shrimp, Stenopus hispidus) .

Pagurus is a genus of hermit crabs in the family Paguridae. Like other hermit crabs, their abdomen is not calcified and they use snail shells as protection. These marine decapod crustaceans are omnivorous, but mostly prey on small animals and scavenge carrion. Trigonocheirus and Pagurixus used to be considered subgenera of Pagurus, but the former is nowadays included in Orthopagurus, while the latter has been separated as a distinct genus.

It is the surviving member of monotypic family Rhynochetidae, order Gruiformes. There are 11 endemic fish species and 14 endemic species of decapod crustaceans in the rivers and lakes of New Caledonia. Some, such as Neogalaxias, exist only in small areas. The nautilus—considered a living fossil and related to the ammonites, which became extinct at the end of the Mesozoic era—occurs in Pacific waters around New Caledonia.

A study conducted by Chris Woods in 1995 examined the foregut morphology of seaweed crabs, shedding light on the digestive system of the understudied spider crab. Brachyura have the most highly developed gut systems of decapod crustaceans. Seaweed crabs have adapted to a macrophagous diet, in other words eating large foods. They have teeth to break down the material they consume and setae, hair-like structures, to aid in the process.

Among these may be mentioned observations on the zoophytes of Cornwall, on the development of the frog, on the metamorphosis of the decapod crustaceans, and the natural history of the mackerel in the Polytechnic Reports for 1842 and 1844; and on the nest of the fifteen-spined stickleback in the Penzance Natural History Transactions, ii. 7983. He contributed to John Ralfs's British Desmidieæ, 1848, and to Thomas Bell's British Stalk-eyed Crustacea, 1853.

Six locomotives with a Decapod type wheel arrangement were built in 1910 by Henschel & Son of Kassel in Germany for a French Colony in Africa. The engines were rejected by French inspectors, however, and they were purchased by the German government for £2,000 each in 1911, on behalf of the Lüderitzbucht-Gesellschaft company who leased the Lüderitzbucht Eisenbahn and shared the profits with the government.Henschel- Lieferliste (Henschel & Son works list), compiled by Dietmar Stresow.

The smaller size of Mediterranean sharks relative to those from the rest of the world may be due to limited food availability and/or the warmer, saltier environment. Some 87% of the diet of Portuguese dogfish in the Mediterranean consists of cephalopods. Bony fishes are a secondary food source, while immature sharks favor the shrimp Acanthephyra eximia, the most common decapod crustacean in their environment. Unlike in other regions, Mediterranean sharks seldom scavenge.

Waldo LaSalle Schmitt (June 25, 1887 – August 5, 1977) was an American biologist born in Washington, D.C. He received his Ph.D. from George Washington University in 1922. In 1948, he received an honorary Doctor of Science degree from the University of Southern California. Schmitt's primary field of zoological investigation was carcinology, with special emphasis on the decapod crustaceans (crabs, lobsters, shrimp, and so on). His bibliography consists of more than seventy titles.

Variation occurs within species, and TSV-resistant strains of shrimp have been developed. Wild stocks are showing increased resistance, perhaps through intense natural selection. Reports of TS in the wild are limited, but in February 1995, the Mexican Fisheries Ministry reported the presence of TSV in wild-type shrimp captured on the border of Mexico and Guatemala. As of 2007, no confirmed reports indicated TSV is infectious to other groups of decapod or nondecapod crustaceans.

The Barbour's seahorse feeds on small shrimp, crustaceans, calanoid copepods and decapod larvae, but has also been known to ingest the larvae of polychaetes and fish. Individuals have well developed spines such as their sharp eye, nose, and double cheek spine. The longest and broadest of the spines is its first dorsal spine. Its tail is relatively short in proportion to its body and has a series of long and short spines along it.

Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in fresh water, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. Many other animals with similar names – such as hermit crabs, king crabs, porcelain crabs, horseshoe crabs, and crab lice – are not true crabs.

Small numbers of other Decapods were built over the next twenty years, mostly for service in steeply graded mountainous areas where power at low speeds was the requirement. The type did not prove as popular as the successful Consolidation (2-8-0) type. Among Decapod users was the Atchison, Topeka and Santa Fe Railway. The engines were tandem compounds but their ongoing reversing limitations became the genesis of the 2-10-2 wheel arrangement.

From 1910 to 1951, the French industry built more than 500 decapods for three railway companies (Paris-Orléans, Nord, Est) and for the national railways (SNCF). Moreover, at the end of World War II, SNCF inherited more than 200 units of German decapods built in France, mostly BR 44. The last decapod, a SNCF 150P, was withdrawn in 1968. All 2-10-0s, of French or of German design, proved reliable and powerful in service.

Marbled crayfish are the only known decapod crustaceans to reproduce only by parthenogenesis. All individuals are female, and the offspring are genetically identical to the parent. Marbled crayfish are triploid animals, which may be the main reason for their parthenogenetic reproduction. It is hypothesized that marbled crayfish originated from an error in meiosis resulting in a diploid gamete, which was then fertilized and created a viable triploid individual in a single generation.

The history of the locomotives starts in 1932, when to cope with increased traffic levels, Marc de Caso designed a new class of 2-10-0 Decapod locomotives: the 5.1200s, later to become the SNCF 2-150.B. In order to increase standardisation, and to reduce operating and maintenance costs, the 5.1200s shared many parts with the third series of Super Pacifics (3.1251 to 3.1290) and the suburban Mikado tank locomotives (4.1200 to 4.1272).

L. tessellata is a small crab growing to a width of about . The carapace is trapezoid in shape and the margin has a distinct tooth-shaped projection on either side, just behind the short-stalked eye. The surface of the carapace is marked into several differently coloured, geometric regions by a network of dark lines giving it the appearance of stained glass. The chelipeds do not have the broad chelae (claws) typical of decapod crabs.

The eyes of some bivalve mollusks, such as the scallop (Pecten) use a concave mirror, the argentea, at the back of the eye, to create an image on the retina. The deep-sea ostracod Gigantocypris has eyes with parabolic reflectors.

Guitarfishes and other cartilaginous fishes are preyed upon by the pigeye shark, particularly off South Africa. Though the pigeye shark will take prey from anywhere in the water column, it tends to hunt close to the sea floor. An apex predator, it feeds mainly on teleost fishes such as croakers, flatfishes, and cutlassfishes, and to a lesser extent on cartilaginous fishes, cephalopods, and decapod crustaceans. It has also been recorded eating gastropods, sea snakes, dolphins, and whale carrion.

The shrimp Palaemon serratus of the infraorder Caridea Shrimp are decapod crustaceans with elongated bodies and a primarily swimming mode of locomotion – most commonly Caridea and Dendrobranchiata. More narrow definitions may be restricted to Caridea, to smaller species of either group or to only the marine species. Under a broader definition, shrimp may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long narrow muscular tails (abdomens), long whiskers (antennae), and slender legs.Shrimp Encyclopædia Britannica.

This proportionality explains, as in other Decapod Crustaceans, that spine size decreases as specimens grow older. As mentioned in the taxonomic section, this genus contains the family's primitive feature of a movable antenna at the basal segment. However, "the development of a spine at the posterior angle of the supraocular eave, and the presence of intercalated spine and antennulary septum seem to attribute a rather high position to this genus." Lastly, there are differences between the sexes.

He runs berserk through the gym. Back at the laboratory, Professor Farnsworth examines a restrained Zoidberg, and determines that it is mating season for Zoidberg's species. The crew flies to Zoidberg's home planet, Decapod 10,arriving 19 hours before the mating frenzy. After a short tour of his "old scuttling grounds", and the stadium where the ceremony of Claw-Plach takes place, Zoidberg sets up a mound on the beach and begins trying to attract a mate.

The cardiac foregut is defined by its sac- shaped structure, thin walls, prepterocardiac ossicle, and postpterocardiac ossicle. Meanwhile the pyloric foregut is characterized by its plates, lateral mesopyloric ossicle, and posterior uropyloric ossicle. Previous studies and staining methods were unable to differentiate the calcified structures. However, recent research completed with Alizarin Red S staining has allowed them to be described with correct terminology, and for comparative analyses to be completed between decapod crustacean species to determine their phylogenetic relationships.

King crab meat is considered a delicacy. King crabs are a taxon of crab-like decapod crustaceans chiefly found in cold seas. Because of their large size and the taste of their meat, many species are widely caught and sold as food, the most common being the red king crab (Paralithodes camtschaticus). King crabs are generally thought to be derived from hermit crab-like ancestors within the Paguridae, which may explain the asymmetry still found in the adult forms.

It is an ambush predator that pounces onto prey and stuns them with electricity, the process taking only a fraction of a second. Once the prey is immobilized, it is manipulated to the mouth with motions of the disc, and swallowed whole. Adults feed almost entirely on small benthic bony fishes, including soles, herring, mullet, gobies, goatfishes, porgies, dragonets, and jack mackerels. Large decapod crustaceans are a minor secondary food source, while very rarely skates may be consumed.
|
|
Major characteristics include a soft leathery abdomen, a wide carapace narrowing at the anterior end much like a trapezoid, similar shaped chelae, and coloration ranging from a clouded green to reddish sometimes with banding along the legs. The name of this decapod is derived from the scale like pattern that covers its legs and partially covers its carapace. The odd structure of the chelae which are spoon-like in nature and are largely covered in setae.

It has not always been possible to replicate these findings in crustaceans. In one study, three decapod crustacean species, Louisiana red swamp crayfish, white shrimp and grass shrimp, were tested for nociceptive behaviour by applying sodium hydroxide, hydrochloric acid, or benzocaine to the antennae. This caused no change in behaviour in these three species compared to controls. Animals did not groom the treated antenna, and there was no difference in movement of treated individuals and controls.

The Chagrin Shale exposed by Euclid Creek contains many different arthropod fossils, including Camarotoechia, Lingula, Nucleata, Orbiculoidea, and five species of Echinocaris. A lone fossil of a decapod, Palaeopalaemon, and indeterminate fragments of the crustacean Mesothyra, have also been found. In 1960, a new species of lobe-finned fish, Chagrinia enodis, was found eroded out of the Chagrin Shale in the Euclid Creek Reservation. The Cleveland Shale along Euclid Creek is known to contain limited fossil remains.

She was excited to be participating in a spy adventure alongside secret agent Steed (although some episodes—"The Removal Men", "The Decapod"—indicate she is not always enthusiastic). Nonetheless, she appears to be attracted to him, and their relationship is somewhat similar to that later portrayed between Steed and Tara King. Her episodes featured musical interludes showcasing her singing performances. The character of Venus underwent some revision during her run, adopting more youthful demeanor and dress.

Decomposition of jelly-falls is largely aided by these kinds of scavengers. In general, echinoderms, such as sea stars, have emerged as the primary consumer of jelly-falls, followed by crustaceans and fish. However, which scavengers find their way to jelly-falls is highly reliant on each ecosystem. For example, in an experiment in the Norwegian deep sea, hagfish were the first scavengers to find the traps of decaying jellies, followed by squat lobsters, and finally decapod shrimp.

The PRR decapod, class I1s, was unlike the Russian decapod; it was huge, taking advantage of the PRR's heavy trackage and high axle loading, with a fat, free-steaming boiler that earned the type the nickname of 'Hippos' on the PRR. Two giant cylinders (30½ x 32 inch) gave the I1s power and their tenders permitted hard and long workings between stops. They were unpopular with the crews, for they were hard riding. The last operations on the PRR were 1957. A small number of other Decapods were ordered by other railroads; the I-2 Decapods built for the Western Maryland Railway were the largest ever built, at almost weight, and are a notable exception to the rule of thumb for the comfort of the ride on a 2-10-0 wheel arrangement, crews said the engines cruised smoothly up to 50mph without becoming a rough ride. (After the running gear was redesigned by the WM) The WM's I-2 are also noted as the strongest Decapods ever built, at 96,315lbs of tractive effort.

An astronaut explores the red dirt surface of an alien planet, where a crab-like creature reaches out of the soil and snips through his space suit. The infection that results transforms him into a cosmic decapod crustacean/human hybrid, with the head and claws of a crayfish or lobster. When he returns to Earth and tries to reconnect with his family, he discovers that he's been the victim of a sinister conspiracy, and takes revenge on those responsible for his family's disappearance.

Slipper lobsters are typically bottom dwellers of the continental shelves, found at depths of up to . Slipper lobsters eat a variety of molluscs, including limpets, mussels and oysters, as well as crustaceans, polychaetes and echinoderms. They grow slowly and live to a considerable age. They lack the giant neurones which allow other decapod crustaceans to perform tailflips, and must rely on other means to escape predator attack, such as burial in a substrate and reliance on the heavily armoured exoskeleton.

Robert Gurney (31 July 1879 – 5 March 1950) was a British zoologist from the Gurney family, most famous for his monographs on British Freshwater Copepoda (1931–1933) and the Larvae of Decapod Crustacea (1942). He was not affiliated with any institution, but worked at home, initially in Norfolk, and later near Oxford. He travelled to North Africa and Bermuda, and received material from other foreign expeditions, including the Terra Nova Expedition (1910–1913) and the Discovery Investigations of the 1920s and 1930s.

Furry lobsters (sometimes called coral lobsters) are small decapod crustaceans, closely related to the slipper lobsters and spiny lobsters. The antennae are not as enlarged as in spiny and slipper lobsters, and the body is covered in short hairs, hence the name furry lobster. Although previously considered a family in their own right (Synaxidae Spence Bate, 1881), the furry lobsters were subsumed into the family Palinuridae in 1990, and molecular phylogenies support the inclusion of the furry lobsters in the family Palinuridae.

Munidopsis serricornis (Galatheidae) Squat lobsters are dorsoventrally flattened crustaceans with long tails held curled beneath the cephalothorax. They are found in the two superfamilies Galatheoidea and Chirostyloidea, which form part of the decapod infraorder Anomura, alongside groups including the hermit crabs and mole crabs. They are distributed worldwide in the oceans, and occur from near the surface to deep sea hydrothermal vents, with one species occupying caves above sea level. More than 900 species have been described, in around 60 genera.

Paratya is distinguished from all other decapod shrimps by the specialized form of the first two pairs of chelipeds, which possess clusters of brushing setae or small hairs to pick up food. This shrimp feeds mainly by scraping detritus from the leaves of aquatic plants (Elodea spp. and milfoils), sometimes with all four chelipeds, bringing the organic material to the mouthparts where larger particles are shredded by the third pair of maxillipeds. It also eats small invertebrates such as midges.

It is a very successful species and is often the first scleractinian coral to colonise a disturbed area. The tangled bushy form of this coral provides a suitable habitat for other animals. A number of symbiotic decapod crustaceans find shelter and protection here and they also obtain food in the form of mucus secreted by the coral. Two species of alpheid shrimps and three species of xanthid crabs are thought to be obligate symbionts and not found living anywhere else.

Neoglyphea, a living glypheoid first recognised by Michèle de Saint Laurent and Jacques Forest The first major focus of Michèle de Saint Laurent's work was the systematics of hermit crabs. In the late 1960s, she revised the family Paguridae, erecting several new genera. She was also involved in describing the hermit crabs of the Calypso expedition from the Atlantic coast of South America, and was on board the Jean Charcot and the Thalassa during their scientific voyages. She also investigated other decapod crustaceans, particularly the Thalassinidea.

Plant fossils include pollen, spores, logs, and other plant macrofossils. Invertebrate fossils include foraminifera (protists that form test shells), sponge spicules, bryozoans, bivalves, gastropods, Spirorbis, beetles, ants, barnacles, decapod crustaceans (crabs, shrimp, lobsters, etc.), ostracodes (seed shrimp), and ophiuroids (brittle stars). Vertebrate fossils include fish and a few rare large mammals, such as walruses, whales, and a mammoth. Walrus remains have been reported on Andrews Island, west of Isle au Haut; Addison Point, northeast of the Schoodic Peninsula; and Gardiner, west-northwest of Isle au Haut.

Moulting requires metabolic energy and the larger the lobster, the more energy is needed; 10 to 15% of lobsters die of exhaustion during moulting, while in older lobsters, moulting ceases and the exoskeleton degrades or collapses entirely leading to death. Lobsters, like many other decapod crustaceans, grow throughout life and are able to add new muscle cells at each moult. Lobster longevity allows them to reach impressive sizes. According to Guinness World Records, the largest lobster ever caught was in Nova Scotia, Canada, weighing .

AT&SF; 2-10-2 No. 3932 In the United States, the type was produced between 1903 and 1930. The first were the Atchison, Topeka and Santa Fe Railway (AT&SF;) engines of the 900 and 1600 series, which were an early type with few advantages over the 2-10-0 Decapod, save their ability to operate in reverse without derailing. By 1919, the AT&SF; was building the definitive type, with the trailing truck supporting a large firebox. These were of the AT&SF; 3800 class.

Zoidberg then lights a flag on fire. This shocks and angers the other citizens, but Zoidberg explains that he does so in order to preserve the freedom that the flag represents and throws it toward the Mobile Oppression Palace, attracting the missile and thus destroying the palace. Zoidberg is declared a hero and is honored by Nixon at a ceremony, where he unveils a new Earth flag, out of which Zoidberg is allowed to take a bite. Zoidberg concludes that Earth, not Decapod 10, is now his true home planet.

Several of the site’s 24 islets provide undisturbed sandy beach habitat for nesting green turtles, as well as forest and shrubland supporting breeding populations of terns and other seabirds. Its coral reefs support a distinct community of marine benthic plants and animals, a diverse decapod crustacean and hydroid fauna, and feeding habitat for migratory shorebirds and seabirds. Seaweed communities are also important. There are no known native terrestrial mammals within the Reserves; introduced black rats were present on South West Coringa Islet for many years, but were eliminated by 1991 after an eradication program.

The constellation of Cancer, the crab, from Urania's Mirror, c. 1825 Crustaceans are an important source of food, providing nearly 10,700,000 tons in 2007; the vast majority of this output is of decapods: crabs, lobsters, shrimps, crayfish, and prawns. Over 60% by weight of all crustaceans caught for consumption are shrimp and prawns, and nearly 80% is produced in Asia, with China alone producing nearly half the world's total. Non-decapod crustaceans are not widely consumed, with only 118,000 tons of krill being caught, despite krill having one of the greatest biomasses on the planet.

In June 2009, Chillon was in Paris pitching a project called Outfinite, which would "pay tribute to sci-fi B movies and blaxploitation pics." The film that became Decapoda Shock, a science fiction action parody film, was filmed between July 2009 and March 2011. In this film, the director allowed himself more spontaneity and improvisation. The film depicts an astronaut infected by an alien crab-like creature, transforming him into a decapod crustacean/human hybrid and whose family has disappeared, both the result of a sinister conspiracy, for which he seeks vengeance.

The golden king crab is a North Pacific king crab, a decapod crustacean. They have five pairs of legs, the front pair carries their claws. Golden king crabs get their name form the orange-brown to golden hue of their shells, which are mostly made of calcium. Like other king crabs, golden king crabs are large and have long, spiny legs; compared with blue and red king crabs, though, they are smaller by a great deal, with a typical weight between 5 and 8 lb, and notably thinner legs.

External anatomy of the common European shrimp, Crangon crangon Shrimp can dart backwards by lobstering. The following description refers mainly to the external anatomy of the common European shrimp, Crangon crangon, as a typical example of a decapod shrimp. The body of the shrimp is divided into two main parts: the head and thorax which are fused together to form the cephalothorax, and a long narrow abdomen. The shell which protects the cephalothorax is harder and thicker than the shell elsewhere on the shrimp and is called the carapace.

The Early Devonian Naefiteuthis has been interpreted as the earliest fossil coleoid, and its shell may be in a partly internalized state. Belemnoids proper appear slightly later in the Early Devonian, and represent the first unambiguous coleoids. The Mazon Creek biota contains a decapod, Jeletzkya, which had ten arms, but the status of its shell is ambiguous as it has not been extracted from the concretion that preserves the only fossil. Accordingly, it has been interpreted as both an internal and an external shell; the specimen may represent a 'squid' or a belemnoid.

Williams' first scientific paper, published in 1952, described six new species of freshwater crayfish from the Ozark Mountains of Arkansas, Missouri and Oklahoma; he continued to publish until his death in 1999, accruing 118 publications in that time. His most important works include monographs on the marine decapod crustaceans of the Carolinas, on the decapods of the Atlantic coast of the United States, and on the lobsters of the world's oceans. He won several awards, including the Crustacean Society's Excellence in Research Award and the American Fisheries Society's Oscar Elton Sette Award.

The diet of the little skate consists mostly of decapod crustaceans and amphipods. Polychaete worms are also an important prey item, while other invertebrates (including isopods, bivalves, squid, sea squirts, and copepods) and small benthic fishes (including sand lances, herring, cunners, and cod) are rarely taken. The importance of crustaceans in the skate's diet increases with size. This species shares its benthic habitat with the similar winter skate; the little skate focuses more on epifauna (organisms living atop the substrate) while the winter skate eats more infauna (burrowing organisms).

Underside view of a living male crab, showing the mouth, gills and legs This group of animals is also known as horsefoot, or saucepan. Some people call the horseshoe crab a "helmet crab", but this common name is more frequently applied to a true crab, a malacostracan, of the species Telmessus cheiragonus. The term "king crab" is sometimes used for horseshoe crabs, but it is more usually applied to a group of decapod crustaceans.

Profilicollis is a genus of acanthocephalan parasites of crustaceans. The status of the genus Profilicollis has been debated, and species placed in this genus were formerly included in the genus Polymorphus. However, research on the morphology of the group and their use of hosts has concluded that Profilicollis and Polymorphus should be regarded as distinct genera, and species previously described as Polymorphus altmani are now referred to as Profilicollis altmani in the literature. Profilicollis parasites infect decapod crustaceans, usually shore crabs, as intermediate hosts, and use many species of shorebirds as definitive (final) hosts.

Natantia (Boas, 1880) is an obsolete taxon of decapod crustaceans, comprising those families that move predominantly by swimming – the shrimp (comprising Caridea and Procarididea), prawns (Dendrobranchiata) and boxer shrimp. The remaining Decapoda were placed in the Reptantia, and consisted of crabs, lobsters and other large animals that move chiefly by walking along the bottom. The division between Natantia and Reptantia was replaced in 1963, when Martin Burkenroad erected the suborder Pleocyemata for those animals that brood their eggs on the pleopods, leaving Dendrobranchiata for the prawns. Under this system, Natantia is a paraphyletic group.

The Glypheoidea (containing the glypheoid lobsters), is a group of lobster- like decapod crustaceans which forms an important part of fossil faunas, such as the Solnhofen limestone. These fossils included taxa such as Glyphea (from which the group takes its name), and Mecochirus, mostly with elongated (often semichelate) chelipeds. This group of decapods is a good example of a living fossil, or a lazarus taxon, since until their discovery in the 1970s, the group was considered to have become extinct in the Eocene. The superfamily Glypheoidea comprises five families.

James Holden stands in front of his locomotive. The locomotive was built for purely political purposes in order to block the passage through Parliament of a new rival scheme for an electric railway. The Decapod was built in 1902 to a design by the GER Chief Draughtsman, Fred Russell under the supervision of the Chief Superintendent, James Holden. The aim was to demonstrate the ability of a steam locomotive to accelerate passenger trains at a rate comparable to electric traction and the electric trams with which the GER was also in competition over short distances.

The most common ones found among A. zebra are some species of the top-snails, true whelks, and margin shells. However, their ecological relationship to A. zebra is not well understood as their small size makes these species difficult to study. Arca zebra has a large impact in the ecology of its habitat as beds of A. zebra serve as both food and shelter for a variety of other shallow water marine organisms. Regions with greater Arca zebra bed density also see greater abundance, richness, and taxonomic distinctness in decapod crustaceans.

The result is an image at half the radius of the eye, which is where the tips of the rhabdoms are. This kind is used mostly by nocturnal insects. In the parabolic superposition compound eye type, seen in arthropods such as mayflies, the parabolic surfaces of the inside of each facet focus light from a reflector to a sensor array. Long-bodied decapod crustaceans such as shrimp, prawns, crayfish and lobsters are alone in having reflecting superposition eyes, which also have a transparent gap but use corner mirrors instead of lenses.

Macdonald was born in the village of Foyers, from Inverness in Scotland.Dow (2003). He attended Foyers Public School from 1913 to 1924 before obtaining a bursary to complete his secondary education at the Inverness Royal Academy, from which he graduated Dux in Art in 1927. He studied natural science at the University of Aberdeen, graduating with a BSc in Forestry in 1930 and in Pure Science (botany and zoology) in 1932, following which he carried out research on decapod crustaceans with the Scottish Fisheries Board and the Plymouth Marine Laboratory.

Cardus crucifer is a species of blind deep-water decapod crustacean from the Atlantic Ocean, the only species in the genus Cardus. It differs from other members of the family Polychelidae in having only four pairs of claws, instead of five, in both sexes. The name Cardus refers to the thistle Carduus, in reference to the spiny thistle-like carapace. It is found in the eastern Atlantic from Portugal to Morocco and around the Azores and Canary Islands, and in the Bahamas, the Caribbean Sea and the Gulf of Mexico, at depths of .

Periclimenaeus is a genus of decapod crustaceans of the family Palaemonidae which is part of the infraorder Caridea. The genus was named by the English carcinologist Lancelot Alexander Borradaile in 1915. He set out the distinguishing features of the genus as: Pericimaenaeus robustus is known only from the type specimen which was collected off Amirante Islands by the Western Indian Ocean Expeditions of Prof. J. Stanley Gardiner and described in 1915 and again in 1917 by Borradaile, it was re-described by Dr A.J. "Sandy" Bruce of the Queensland Museum in 2005.

The crew celebrates Freedom Day, a day where one can do anything they want, regardless of the consequences. Dr. Zoidberg seems passionate about the holiday, as he loves the idea of freedom, something he did not have on his home planet Decapod 10. At the big Freedom Day celebration in Washington, D.C., Earth President Richard Nixon's head unveils the Earth flag "Old Freebie" to celebrate the spirit of the holiday but the flag is eaten by Zoidberg. Zoidberg feels this is an expression of his freedom on Freedom Day; however, the rest of the crowd sees him as a traitor.

In 1927 he retired on his 50th birthday with the rank of lieutenant colonel. He was attached to the 7th Lancers as part of the No. 57 Native Field Hospital, during the Boxer Rebellion and received the China War Medal for his part in the Siege of the International Legations in Peking, for which he also received the Military Order of the Dragon from the Chinese Government. His scientific work included research on quinine and its salts and he was Surgeon-Naturalist on board R.I.M.S. Investigator. His other scientific interest was the decapod crustaceans of the Indian Ocean.

Anthropogenic noise can have negative effects on invertebrates that aid in controlling environmental processes that are crucial to the ecosystem. There are a variety of natural underwater sounds produced by waves in coastal and shelf habitats, and biotic communication signals that do not negatively impact the ecosystem. The changes in behavior of invertebrates vary depending on the type of anthropogenic noise and is similar to natural noisescapes. Experiments have examined the behavior and physiology of the clam (Ruditapes philippinarum), the decapod (Nephrops norvegicus), and the brittlestar (Amphiura filiformis) that are affected by sounds resembling shipping and building noises.

While scientists previously grouped the genus Carpilius with other crabs of the Xanthiae family, recent research on mitochondrial gene fragments of the Carpilius crabs has granted it its status as a separate monotypic genus within its distinct family, Carpiliidae. Fossil records of crabs classified within the family Carpiliidae have linked it to the genera Palaeocarpilius, which was present during the middle to upper Eocene Epoch approximately 56 million years ago and found in what is now modern-day Europe, India, and Egypt.Schweitzer, C.E., Feldmann, R.M., Tucker, A.B., Berglund, R.E., 2000.

The collection began in 1894 (then at the Museu Paulista) with the work of Hermann von Ihering and his colleagues, including Ernest Garbe and Hermann von Lüderwaldt. In 1939 the collection was transferred to the Department of Zoology, where it remained until 1969 (when it was incorporated into the University of São Paulo). In 1961 the Department of Zoology hired Gustavo Augusto Schmidt de Melo, who has participated in a number of expeditions emphasizing the collection of decapod crustaceans in marine and continental waters. Since 2003, the collection has been curated by zoologist Marcos Domingos Siqueira Tavares.

The museum is on the original station and yard site of the Hanko–Hyvinkää railway. In addition to the station building, there is a roundhouse and several other preserved buildings, mainly from the 1870s. Unique objects are on display, including the only surviving imperial train of the Russian Emperor. The locomotives include the British Neilson and Company locomotive (0-6-0 No 1427) dating 1869, a British Beyer Peacock locomotive dating from 1868, and a 2-10-0 steam locomotive Tr2 1319 ALCO No 75214 built 1947, which is one of 20 Russian "Decapod" locomotives sold to Finland.

Today's middle ground reef ecosystem represents the northernmost scope of mid- shelf octocoral communities in North America. It is a prehistoric coral-reef complex that has bio-similarities to modern patch-reefs, and a species distribution that includes both Carolinian and Caribbean components. The fish species are markedly tropical, with stony coral, gorgonians, and sponge dominating the community that relies upon the existence of the Loop Current. Currently, there are 170 species of fish, 103 species of algae, approximately 40 sponges, 75 mollusks, 56 decapod crustaceans, 41 polychaetes, 23 echinoderms and 23 species of stony corals.

A number of separate water masses surround Echo Bank, which originate from regions such as the North Atlantic, the South Atlantic and Antarctica and are stacked over each other. In general, the region is under the influence of the nutrient-poor waters of the subtropical gyre and the upwelling regions off northwestern Africa. Bottom net trawlings of Echo Bank have revealed remarkable findings such as a rich decapod fauna. African cuttlefish, the barnacle Poecilasma aurantia, the common cuttlefish, the elegant cuttlefish and the giant African cuttlefish occur at Echo Bank; the giant African cuttlefish is the most commercially important cuttlefish in the region.

Buchanan's early research interests were in the development of respiratory organs in decapod Crustacea, as well as poylchaete worms, which she researched at the University College London (1889–1892), the Plymouth Marine Laboratory (1891), and the Royal Dublin Society (1893). By 1894, Buchanan's primary research interests had changed to the electrical effects in muscle, which she researched at J. Burdon Sanderson's laboratory in Oxford (1894-1905), which then progressed into an interest in the heartbeat and form of the electrocardiogram, and transmission of reflex impulses in mammals, birds, and reptiles, which she researched at the Oxford University Museum laboratory (1904-1913).

The wheel arrangement evolved in the United States from the 2-10-0 Decapod of the Atchison, Topeka and Santa Fe Railway (ATSF). Their existing 2-10-0 tandem compound locomotives, used as pushers up Raton Pass, encountered problems reversing back down the grade for their next assignments since they were unable to track around curves at speed in reverse and had to run very slowly to avoid derailing. Consequently, the ATSF added a trailing truck to the locomotives which allowed them to operate successfully in both directions. These first locomotives became the forerunners to the entire family.

Callichirus major was first described as Callianassa major by Thomas Say in 1818, specifically in the Gulf of Mexico and East Florida. Its genus was renamed Callichirus in 1866 by William Stimpson. It used to be classified in the infraorder Thalassinidea (ghost shrimp) of decapod crustaceans until this infraorder was proven to be paraphyletic in 2009, after which the family Callianassidae, in which C. major is included, was definitely placed in the infraorder Axiidae (de Saint Laurent, 1979). A supposed Brazilian species described as Anomalocaris macrotelsonis (Ortmann, 1893) was eventually discovered in 1974 to be the fourth larval stage of C. major.

Flamme Type 10 pacific Locomotives with ten driving wheels were rare in British railway history. One specialist exception, the GER Decapod, had been built in 1902, but the main heavy mineral locomotive design was the 0-8-0, on both the L&YR; and the LNWR. Train weights were increasing though and there was some demand for a more powerful locomotive, particularly for the steep gradients across the Pennines from the Lancashire Coalfield to the port of Goole. It was felt that a more powerful single locomotive would avoid the need for double-heading on coal trains.

The medial giant interneuron (MG) is an interneuron in the abdominal nerve cord of crayfish. It is part of the system that controls the caridoid escape reaction of crayfish, clawed lobsters, and other decapod crustaceans. Crayfish have a pair of medial giants running the length of the entire animal, and are the largest neurons in the animal. When a crayfish is given a sudden visual or tactile stimulus to the front part of the animal, the MG activates fast flexor motor neurons that cause the abdomen to flex, resulting in the crayfish moving directly backward, away from the source of the stimulation.

A damaged decapod was collected in 1908 by the USFC Albatross in the Philippines. It was deposited in the United States National Museum, where it remained unidentified until Michèle de Saint Laurent examined it in 1975. Her colleague Jacques Forest recognised that it represented the first known extant species of the infraorder Glypheidea, which was thought to have been extinct since the Eocene, a conclusion endorsed by Fenner A. Chace, Jr. and Raymond B. Manning. Parasitic copepods were discovered on the gills of the Neoglyphea specimen, and were described in a 1976 paper by Roger F. Cressey.

The three cylinder tank locomotive was in fashion at this time, as a means of achieving good acceleration from rest, owing to their more even power delivery and the reduced risk of wheelslip.Ahrons, British Steam Railway Locomotive, pp. 337—340 This three-cylindered pattern had begun with Holden's Decapod of 1902 and carried through into Worsdell and Raven's fast passenger tank locomotives of 4-6-2T and 4-4-4T layout for the North Eastern Railway in 1910 and 1913. Worsdell also designed a comparable heavy shunter of his own, the Class X, although this used the 4-8-0T layout with a leading bogie, rather than trailing.

The two main groups of squat lobsters share most features of their morphology. They resemble true lobsters in some ways, but are somewhat flattened dorsoventrally, and are typically smaller. Squat lobsters vary in carapace length (measured from the eye socket to the rear edge), from in the case of Munidopsis aries, down to only a few millimetres in the case of Galathea intermedia and some species of Uroptychus. As in other decapod crustaceans, the body of a squat lobster may be divided into two main regions: the cephalothorax (itself made up of the cephalon, or head, and the thorax), and the pleon or abdomen.

Lobsters live up to an estimated 45 to 50 years in the wild, although determining age is difficult. In 2012, a report was published describing how growth bands in calcified regions of the eyestalk or gastric mill in shrimps, crabs and lobsters could be used to measure growth and mortality in decapod crustaceans. Without such a technique, a lobster's age is estimated by size and other variables; this new knowledge "could help scientists better understand the population and assist regulators of the lucrative industry". Research suggests that lobsters may not slow down, weaken or lose fertility with age, and that older lobsters may be more fertile than younger lobsters.

The Decapod developed mainly under Chief Draughtsman Frederick Vernon Russell was an extraordinary endeavour to develop a steam locomotive which could perform at the level of electric traction.Skeat 1953 It was built in 1902 to forestall an imminent scheme for an electrified railway out of London to suburbs served by the GER. Since the proponents of the scheme had a slogan about electric trains accelerating to thirty miles an hour in thirty seconds, Holden resolved to obtain the same performance with steam traction. A massive boiler with Wootten firebox, three cylinders each with its own blastpipe cone, and ten smallish driving wheels ensured a lively acceleration.

The Interfaith Association of Animal Chaplains encourages animal ministry groups to adopt a policy of recognising and valuing sentient beings. In 1997 the concept of animal sentience was written into the basic law of the European Union. The legally binding protocol annexed to the Treaty of Amsterdam recognises that animals are "sentient beings", and requires the EU and its member states to "pay full regard to the welfare requirements of animals". The laws of several states include certain invertebrates such as cephalopods (octopuses, squids) and decapod crustaceans (lobsters, crabs) in the scope of animal protection laws, implying that these animals are also judged capable of experiencing pain and suffering.

Nephrops norvegicus is the host to a number of parasites and symbionts. A number of sessile organisms attach to the exoskeleton of N. norvegicus, including the barnacle Balanus crenatus and the foraminiferan Cyclogyra, but overall Nephrops suffers fewer infestations of such epibionts than other decapod crustaceans do. In December 1995, the commensal Symbion pandora was discovered attached to the mouthparts of Nephrops norvegicus, and was found to be the first member of a new phylum, Cycliophora, a finding described by Simon Conway Morris as "the zoological highlight of the decade". S. pandora has been found in many populations of N. norvegicus, both in the north Atlantic and in the Mediterranean Sea.

The Erie crews had acquired the knack of finding something wrong with their engines, keeping them conveniently immobilized when it was time for work. The agreement ended. A Mikado locomotive of the Baltimore and Ohio Both roads faced the same problems at Clarion Junction: how best to get heavy trains over Clarion Hill. By the end of the 19th century, the Erie kept two engines there, while the BR&P; had up to five. Initially, they used 2-8-0 Consolidations, but the limitations of these antiquated locomotives forced adoption of specialized engines, such as the 4-8-0 Mastodon in 1896. This did not suffice, leading to the heavier Y Class 2-10-0 Decapod in 1907.

Dr. John A. Zoidberg (referred to only by his last name Zoidberg) is a fictional character in the television series Futurama. He is a Decapodian, a crustacean-like species of alien, who works as the staff doctor for Planet Express, despite his woeful understanding of human physiology and allusions to his questionable credentials. His character parodies the supposed wealth and automatic respect of modern doctors—for example, his incompetence at human medicine makes him extremely poor despite his profession, and he is implied to be frequently homeless when not at work. The Decapod (named after the actual Decapoda order of ten-footed crustaceans) are an extended parody on Yiddish culture—the bigger joke being that shellfish are not kosher.

Young fish prefer planktonic organisms, predominantly decapod and fish larvae; fish reaching sexual maturity prey on shrimp and small fish, while mature fish feed almost exclusively on small fish. The fish species preferred by bar jack appear to be mostly small sand dwellers such as blennies and gobies or small reef dwellers including wrasses, butterflyfish and filefish, with the diet of the latter leading to the accumulation of coral derived ciguatera toxin in the jack's flesh. Other lesser taken prey items include gastropods, nematodes and benthic algae as well as a range of crustaceans. Feeding intensity varies throughout the year, and is strongly correlated to changes in the precipitation and wind during cyclical shifts in the climate.

The hadal zone is the deepest part of the marine environment Marine life decreases with depth, both in abundance and biomass, but there is a wide range of metazoan organisms in the hadal zone, mostly benthos, including fish, sea cucumber, bristle worms, bivalves, isopods, sea anemones, amphipods, copepods, decapod crustaceans and gastropods. Most of these trench communities probably originated from the abyssal plains. Although they have evolved adaptations to high pressure and low temperatures such as lower metabolism, intra-cellular protein-stabilising osmolytes, and unsaturated fatty acids in cell membrane phospholipids, there is no consistent relationship between pressure and metabolic rate in these communities. Increased pressure can instead constrain the ontogenic or larval stages of organisms.

Johannes Govertus de Man (May 2, 1850 in Middelburg - January 9, 1930 in Middelburg), was a Dutch biologist. He was assistant curator at the (Dutch for national natural history museum) in Leiden, where he specialised in free- living nematodes and decapod crustaceans, although he also wrote papers on flatworms, sipunculids and, in his dissertation only, vertebrates. His change away from vertebrates disappointed the director of the museum, and de Man left his job there after eleven years. For the rest of his life, de Man worked at his parents' house in Middelburg and later at a house near the shore at Yerseke in the Oosterschelde estuary, relying on his family's private income.

This is achieved after several moults which occur every 3–8 weeks. Each shrimp starts out as a male, but after a few moults will become a hermaphrodite allowing them to function as both male and female in interactions with another shrimp; these shrimp have no pure female form. This form of sexual maturation is scientifically described as 'protandric simultaneous hermaphroditism' and is unique to Lysmata shrimp amongst other decapod crustaceans. In one spawning, adult shrimp will lay between 200–500 eggs which are initially attached to the pleopods and are greenish in colour; the eggs swell and lighten in colour before hatching and a few will turn silver on the day of hatching.

Thalassinidea is a former infraorder of decapod crustaceans that live in burrows in muddy bottoms of the world's oceans. In Australian English, the littoral thalassinidean Trypaea australiensis is referred to as the yabby (a term which also refers to freshwater crayfish of the genus Cherax), frequently used as bait for estuarine fishing; elsewhere, however, they are poorly known, and as such have few vernacular names, "mud lobster" and "ghost shrimp" counting among them. The burrows made by thalassinideans are frequently preserved, and the fossil record of thalassinideans reaches back to the late Jurassic. The group was abandoned when it became clear that it represented two separate lineages, now both recognised as infraorders: Gebiidea and Axiidea.

One they attain a mantle length of greater than 4mm decapod crustaceans and cephalopods are the most important prey items. O. antillarum has a number of predators and these include epipelagic and mesopelagic fishes and they have been recorded in the diets of fish such as common dolphinfish (Coryphaena hyppurus), Atlantic sailfishes (Istiophorus albicans), skipjack tuna (Katsuwonus pelamus), white marlin (Tetrapturus albidus), albacore (Thunnus alalunga), yellowfin tuna (Thunnus albacares), bigeye tuna (Thunnus obesus), swordfish (Xiphias gladius). They are also preyed upon by cetaceans) including the pygmy sperm whale (Kogia breviceps) and orca (Orcinus orca). With bony fish, O. antillarum are the most important component of the winter diet of yellowfin tuna off Brazil.

GER Class D56 in original Great Eastern blue livery with decorative features as depicted in a 1910 colour plate by W.J. Stokoe. GER Class T26 no 420 2-4-0 (later LNER Class E4) An official GER picture from 1902 showing CME James Holden alongside the unique 0-10-0T engine Decapod Between 1880 and 1922 the Great Eastern produced some distinctive locomotives, and several of these have been preserved. Almost all of the Great Eastern's locomotives were, after 1880, built at Stratford Works and many lasted until the end of steam on the Great Eastern. Express services on the GER were latterly in the hands of the Class S69 (LNER class B12) locomotives.

Individuals may be found on most segments of the lobster's mouthparts, but are generally concentrated on the central parts of the larger mouthparts, from the mandible to the third maxilliped. The most significant parasite of N. norvegicus is a dinoflagellate of the genus Hematodinium, which has caused epidemic infection in fished populations of N. norvegicus since the 1980s. Hematodinium is a genus that contains major pathogens of a wide variety of decapod crustaceans, although its internal taxonomy is poorly resolved. The species which attacks N. norvegicus causes a syndrome originally described as "post-moult syndrome", in which the carapace turns opaque and becomes highly pigmented, the haemolymph becomes milky white, and the animal appears moribund.

From a palaeontological point of view the Glencartholm volcanic zone is of special interest, as the calcareous shale associated with the tuffs has yielded a large number of new species of fishes, decapod crustaceans, phyllopods and scorpions. The Triassic rocks rest uncomfortably on all older formations within the county. In the tract along the Solway Firth they repose on the folded and eroded edges of the Carboniferous strata, and when traced westwards to the Dumfries basin they rest directly on the Silurian platform. They occur in five areas: :(1) between Annan and the mouth of the Esk (the Scottish portion of the Solway Basin), :(2) the Dumfries basin (Lower Nithsdale), :(3) the Thornhill basin (Middle Nithsdale), :(4) the Lochmaben basin (Middle Annandale), :(5) Upper Annandale.

The railroad and its predecessors would roster a total of eight steam locomotives over the years, all bought second hand and none with a trailing truck. Three of these were camelback locomotives and the wheel arrangements included 4-4-0, 2-6-0, 4-6-0, and 2-8-0. The line's predecessor, the Middletown and Unionville Railroad (M&U;), relied on the nearby New York, Ontario and Western shops for locomotive repairs and inspections and rented fifty-six different O&W; locomotives in thirteen classes while its own was in the O&W; shops. On April 23, 1944, the M&U; retired the last railroad-owned steam locomotive and thereafter leased O&W; locomotives and then NYS&W; 2-10-0 "decapod" steam locomotives.

Outside North America, the largest fleet of locomotives was the Class P36 of the Sovetskie Zheleznye Dorogi (SZhD) or Soviet Railways, of which 251 were built by the Kolomna locomotive works between 1949 and 1956. As the last Soviet standard class steam locomotive, the Class P36 shared some common components and design attributes with earlier standard Soviet designs such as the L class Decapod type and LV class Santa Fe type, as well as some common attributes with the P34 class Mallet and P38 class Yellowstone type Mallet. For example, the P36 and LV classes shared the same feedwater heater, made by the Bryansk machine factory. Apart from a trio of fully streamlined Baltic type locomotives, they were the only semi-streamlined steam locomotives built in Russia.

Because of this, and the unusual (and at the time totally unknown) anatomy of pterosaurs, the specimen was originally misidentified as a decapod crustacean when it was first studied by Ignaz von Born, a prominent Enlightenment naturalist. In 1871, the specimen was sold, along with the rest of Maria Anna's collection, to the Royal Hungarian University of Buda in Hungary, from which it was later transferred to the collection of Pest University when the university relocated. (In 1950, the name of the university changed again to Eötvös Loránd University). In 1856, Hermann von Meyer illustrated the Pester Exemplar, and designated it the type specimen of his new species Pterodactylus micronyx after comparison with the newly recognized and better-preserved pterosaur specimens, all of which were lumped together at that time into the single genus Pterodactylus.

Raymond John Adamson (7 July 1920 - 25 March 2002) was a British television actor. Born in Beckenham, then in Kent, he made his TV debut in 1956, playing a constable in David Copperfield. He became typecast playing policemen or lawmen, also playing policeman in series such as Oliver Twist (1962), Out of This World (1962), Dixon of Dock Green (1964), The Baron (1966), and New Scotland Yard (1972) and he also played a senator in Bergerac in the early 1980s. Other appearances include The Saint (1966), The Avengers (in the episodes The Decapod (1962), The Grandeur That Was Rome (1963), The Avengers (1969)), Randall and Hopkirk (Deceased) (in the episode Murder Ain't What it Used to Be) (1969), Within These Walls (1974-5) and the short film The Orchard End Murder (1980).

This is the highest figure thus far measured from any shark, though it also reflects the concentration of force at the tooth tip. Dense aggregations of young sharks, forming in response to feeding opportunities, have been documented in the Indian Ocean. The known diet of the dusky shark encompasses pelagic fishes, including herring and anchovies, tuna and mackerel, billfish, jacks, needlefish and flyingfish, threadfins, hairtails, lancetfish, and lanternfish; demersal fishes, including mullets, porgies, grunts, and flatheads, eels, lizardfish, cusk eels, gurnards, and flatfish; reef fishes, including barracudas, goatfish, spadefish, groupers, scorpionfish, and porcupinefish; cartilaginous fishes, including dogfish, sawsharks, angel sharks, catsharks, thresher sharks, smoothhounds, smaller requiem sharks, sawfish, guitarfish, skates, stingrays, and butterfly rays; and invertebrates, including cephalopods, decapod crustaceans, barnacles, and sea stars. Very rarely, the largest dusky sharks may also consume sea turtles, marine mammals (mainly as carrion), and human refuse.

Under the Whyte notation for the classification of steam locomotives, 2-10-0 represents the wheel arrangement of two leading wheels on one axle, ten powered and coupled driving wheels on five axles, and no trailing wheels. This arrangement was often named Decapod, especially in the United States, although this name was sometimes applied to locomotives of 0-10-0 "Ten-Coupled" arrangement, particularly in the United Kingdom. Notable German locomotives of this type include the war locomotives of Class 52. These locomotives were popular in Europe, particularly in Germany and Russia; British use of the type was confined to the period during and after World War II. In the United States, the 2-10-0 was not widely popular but was a favorite of a small number of railroads which operated mostly in mountainous terrain.

Small and light-footed, these Russian decapods proved popular with smaller railroads, and many of them remained in service long after the USRA's control of the railroads ceased. Many indeed lasted until the end of steam on those railroads. Russian Decapod, showing the large gap between the boiler and drivers, typical of locomotives designed for Russia Swengel suggested the 2-10-0 arrangement was 'obsolete' by 1916, when the Pennsylvania Railroad (PRR) commenced an experiment with a 2-10-0 locomotive at its Juniata plant. Most 10 coupled engines constructed for U.S. railroads during World War 1 were of the USRA 2-10-2 arrangement, but the PRR committed to 122 of the 2-10-0s. Swengel argued this commitment to the 2-10-0, nicknamed "Deks", was controversial even in 1916 and was more so in 1922 when the PRR placed additional orders.

Aristaeomorpha foliacea is a large decapod crustacean, a shrimp or prawn which has a firm and, flexible and light red exoskeleton and black eyes. In mature females black colour of the black ovaries darkens the dorsal part of the abdomen. There is a slight keel along the dorsal midlines of the third segment which becomes more probounced on the next three segments, ending in a sharp posterior point. It has long pleopods, antennal, hepatic and branchiostegal spines on its carapace, a very short upper antennal flagella, strong spines to the rear of the midpoint on the third to sixth abdominal segments, a telson with four small mobile lateral spines, the females have an open telicum and the species shows secondary sexual dimorphism in body size and the length of the rostrum with the adult females being larger and having a longer rostrum, extending well beyond the antennal scale.
