Lobster
Lobsters are Malacostraca, malacostracans Decapoda, decapod crustaceans of the family (biology), family Nephropidae or its Synonym (taxonomy), synonym Homaridae. They have long bodies with muscular tails and live in crevices or burrows on the sea floor. Three of their five pairs of legs have claws, including the first pair, which are usually much larger than the others. Highly prized as seafood, lobsters are economically important and are often one of the most profitable commodities in the coastal areas they populate. Commercially important species include two species of ''Homarus'' from the northern Atlantic Ocean and Scampi (other), scampi (which look more like a shrimp, or a "mini lobster")—the Northern Hemisphere genus ''Nephrops'' and the Southern Hemisphere genus ''Metanephrops''. Distinction Although several other groups of crustaceans have the word "lobster" in their names, the unqualified term "lobster" generally refers to the clawed lobsters of the fam ...

Homarus Gammarus
''Homarus gammarus'', known as the European lobster or common lobster, is a species of clawed lobster from the eastern Atlantic Ocean, Mediterranean Sea and parts of the Black Sea. It is closely related to the American lobster, ''H. americanus''. It may grow to a length of and a mass of , and bears a conspicuous pair of claws. In life, the lobsters are blue, only becoming "lobster red" on cooking. Mating occurs in the summer, producing eggs which are carried by the females for up to a year before hatching into planktonic larvae. ''Homarus gammarus'' is a highly esteemed food, and is widely caught using lobster pots, mostly around the British Isles. Description ''Homarus gammarus'' is a large crustacean, with a body length up to and weighing up to , although the lobsters caught in lobster pots are usually long and weigh . Like other crustaceans, lobsters have a hard exoskeleton which they must shed in order to grow, in a process called ecdysis (molting). This may occu ...

Homarus
''Homarus'' is a genus of lobsters, which include the common and commercially significant species ''Homarus americanus'' (the American lobster) and '' Homarus gammarus'' (the European lobster). The Cape lobster, which was formerly in this genus as ''H. capensis'', was moved in 1995 to the new genus ''Homarinus''. Description ''Homarus'' is one of three extant genera of clawed lobsters to show dimorphism between claws – a specialisation into a crushing claw and a cutting claw. The other similar genera are '' Nephrops'', which is much more slender, and has grooves along the claws and the abdomen, and '' Homarinus'', the Cape lobster from South Africa, which is even smaller, and has hairy claws. tp://ftp.fao.org/docrep/fao/009/t0411e/t0411e09.pdf Subfamily Nephropinae Dana, 1852 pp. 51–86 in Holthuis (1991). While analyses of morphology suggest a close relationship between ''Homarinus'' and ''Homarus'', molecular analyses using mitochondrial DNA reveal that they are not ...

Cape Lobster
The Cape lobster, ''Homarinus capensis'', is a species of small lobster that lives off the coast of South Africa, from Dassen Island to Haga Haga. Only a few dozen specimens are known, mostly regurgitated by reef-dwelling fish. It lives in rocky reefs, and is thought to lay large eggs that have a short larval phase, or that hatch directly as a juvenile. The species grows to a total length of , and resembles a small European or American lobster; it was previously included in the same genus, ''Homarus'', although it is not very closely related to those species, and is now considered to form a separate, monotypic genus – ''Homarinus''. Its closest relatives are the genera ''Thymops'' and '' Thymopides''. Distribution and ecology The Cape lobster is endemic to South Africa. It occurs from Dassen Island, Western Cape in the west to Haga Haga, Eastern Cape in the east, a range of . Most of the known specimens were regurgitated by fish caught on reefs at depths of .

Seafood
Seafood is any form of Marine life, sea life regarded as food by humans, prominently including Fish as food, fish and shellfish. Shellfish include various species of Mollusca, molluscs (e.g., bivalve molluscs such as clams, oysters, and mussels, and cephalopods such as octopus and squid), crustaceans (e.g. shrimp, crabs, and lobster), and echinoderms (e.g. sea cucumbers and sea urchins). Historically, marine mammals such as cetaceans (whales and dolphins) as well as Pinniped, seals have been eaten as food, though that happens to a lesser extent in modern times. Edible sea plants such as some Edible seaweed, seaweeds and microalgae are widely eaten as :edible seaweeds, sea vegetables around the world, especially in Asia. Seafood is an important source of (animal) protein in many Diet (nutrition), diets around the world, especially in coastal areas. Semi-vegetarianism, Semi-vegetarians who consume seafood as the only source of meat are said to adhere to pescetarianism. The harv ...

Metanephrops
''Metanephrops'' is a genus of lobsters, commonly known as scampi. Important species for fishery include '' Metanephrops australiensis'' (Australian scampi) and '' Metanephrops challengeri'' (New Zealand scampi). It differs from other lobsters such as '' Homarus'' and '' Nephrops norvegicus'' in that its two main claws are of equal size, rather than being differentiated into a ''crusher'' and a ''pincher''. There are 18 extant species recognised in the genus: Species *'' Metanephrops andamanicus'' (Wood-Mason, 1891) *'' Metanephrops arafurensis'' (De Man, 1905) *'' Metanephrops armatus'' Chan & Yu, 1991 *'' Metanephrops australiensis'' (Bruce, 1966) *'' Metanephrops binghami'' (Boone, 1927) *''Metanephrops boschmai'' (Holthuis, 1964) *'' Metanephrops challengeri'' (Balss, 1914) *'' Metanephrops formosanus'' Chan & Yu, 1987 *''Metanephrops japonicus'' (Tapparone-Canefri, 1873) *'' Metanephrops mozambicus'' Macpherson, 1990 *'' Metanephrops neptunus'' (Bruce, 1965) *''Metanephro ...

Crustaceans
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of Arthropod, arthropods that are traditionally a part of the subphylum Crustacea (), a large, diverse group of mainly aquatic animal, aquatic arthropods including decapoda, decapods (shrimps, prawns, crabs, lobsters and crayfish), ostracoda, seed shrimp, branchiopoda, branchiopods, argulidae, fish lice, krill, remipedes, isopods, barnacles, copepods, Mysida, opossum shrimps, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the Hexapoda, hexapods (insects and entognathans) emerged deep in the Crustacean group, with the completed pan-group referred to as Pancrustacea. The three classes Cephalocarida, Branchiopoda and Remipedia are more closely related to the hexapods than they are to any of the other crustaceans (oligostracans and multicrustaceans). The 67,000 described spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thaumastochelopsis
The family Thaumastochelidae contains five known species of deep-sea lobsters, three in the genus ''Thaumastocheles'', and two in the genus ''Thaumastochelopsis''. The fifth species was discovered in the ten–year Census of Marine Life. These creatures are distinguished from other clawed lobsters by their blindness (an adaptation to deep-sea life), and by their single elongated, spiny chela. The family Thaumastochelidae is now more usually subsumed into the lobster family Nephropidae. Species The five species are as follows: *''Thaumastocheles'' **''Thaumastocheles dochmiodon'' Chan & de Saint Laurent, 1999 is found in the Timor Sea. **''Thaumastocheles japonicus'' Calman, 1913, the "Pacific pincer lobster", is endemic to the Sea of Japan. **''Thaumastocheles zaleucus'' Thomson, 1873, the "Atlantic pincer lobster" or "Atlantic deep-sea lobster", is endemic to the Caribbean region. *''Thaumastochelopsis'' **''Thaumastochelopsis brucei'' Ahyong, Chu & Chan, 2007 lives in t ...

Dinochelus
''Dinochelus ausubeli'' is a small deep sea lobster discovered in 2007 in the Philippines during the Census of Marine Life and described in 2010 in the new genus ''Dinochelus''. Its two claws are very different in size, are elongated, and bear many long teeth on the inner surface. It is sometimes dubbed the terrible claw lobster because of its claws. Description ''Dinochelus ausubeli'' has a carapace length of around , and is in life mostly translucent white, with reddish pink colouring near the middle of the carapace, on the tail fan, on the antennae, and on the first pereiopods (including the claws). Its two claws are very different in size. Distribution and discovery ''Dinochelus ausubeli'' is only known from its type locality, , off the coast of Luzon in the Philippines. It was found by trawling at a depth of around in 2007, as part of the Census of Marine Life, a major effort to document marine life in the first decade of the 21st century. It was described in 2010 by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
