Nephropidae
Lobsters are a family (Nephropidae, synonym Homaridae) of marine crustaceans. 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 coastal areas they populate. Commercially important species include two species of ''Homarus'' from the northern Atlantic Ocean and 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 family Nephropidae. Clawed lobsters are not closely related to spiny lobsters or slipper lobsters, which have no cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 .

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: *''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) *''Metanephrops rubellus'' (Moreir ...

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 sister ...

Jagtia
''Jagtia kunradensis'' – the only species in the genus ''Jagtia'' – is a species of lobster that lived in the Upper Maastrichtian age of the Cretaceous period. It was described in 1998 by Dale Tshudy and Ulf Sorhannus of Edinboro University of Pennsylvania in the ''Journal of Paleontology'', based on material from the type locality of the Maastricht Formation. ''Jagtia'' differs from other genera of fossil and extant lobsters by no single feature, but by a combination of characteristics, mostly based on the patterns of grooves on the carapace. The genus is named after John J. M. Jagt, curator at the Natuurhistorisch Museum Maastricht ("Maastricht Natural History Museum"), while the specific epithet ' records the type locality, Kunrade, Limburg, south-eastern Netherlands. An initial morphological analysis suggested that the closest relatives of ''Jagtia'' might be the extant genera ''Thymops ''Thymops birsteini'', the Patagonian lobsterette, is a species of lobster ...

Thymopides
''Thymopides'' is a genus of deep-water lobsters, comprising the two species ''Thymopides grobovi'' and ''Thymopides laurentae''. Distribution Two species are included in the genus ''Thymopides''. *''Thymopides grobovi'' is found around Heard Island and the Kerguelen Archipelago in the southern Indian Ocean at depths of . *''Thymopides laurentae'' is only known from a single hydrothermal vent on the Mid-Atlantic Ridge at a depth of (). Description ''Thymopides'' differs from related genera such as ''Homarus'', ''Homarinus'' and '' Nephrops'' in having the first pair of pereiopods of similar size and shape, rather than one "crusher" and one "cutter" claw. It differs from others, such as '' Metanephrops'' and ''Eunephrops'' by the lack of a carina behind the antennal spine, by the smaller size of some spines and by the smaller, unpigmented eyes. Taxonomy The genus was first described by R. N. Burukovsky and B. S. Averin in 1976 under the name ''Bellator'', in a paper in the ''Ru ...

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. 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 the Coral Sea ...

Nephrops
''Nephrops'' is a genus of lobsters comprising a single extant species, ''Nephrops norvegicus'' (the Norway lobster or Dublin Bay prawn), and several fossil species. It was erected by William Elford Leach in 1814, to accommodate ''N. norvegicus'' alone, which had previously been placed in genera such as ''Cancer'', '' Astacus'' or ''Homarus''. ''Nephrops'' means "kidney eye" and refers to the shape of the animal's compound eye. Although the species in the genus '' Metanephrops'' were previously included in ''Nephrops'', molecular phylogenetics suggests that the two genera are not sister taxa, ''Nephrops'' being more closely related to ''Homarus'' than either is to ''Metanephrops''. Most of the fossil species assigned to the genus ''Nephrops'' are known only from partial remains, and their affinities are not certain. They include: *''Nephrops reedi'' Carter, 1898 – Pliocene, England *''Nephrops costatus'' Rathbun, 1918 – Pleistocene, Panama *''Nephrops maoensis'' Rathbun, 1 ...
