Pagurus
''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. Species Some 170 species are presently placed in ''Pagurus''; many others have been placed here at one time but are now assigned to other genera of Paguroidea. The following list is current : *''Pagurus acadianus'' Benedict, 1901 *''Pagurus alabamensis'' Rathbun, 1935 † *''Pagurus alaini'' Komai, 1998 *''Pagurus alatus'' Fabricius, 1775 *''Pagurus albidianthus'' de Saint Laurent & McLaughlin, 2000 *''Pagurus albus'' (Benedict, 1892) *''Pagurus alcocki'' (Balss, 1911) *'' Pagurus aleuticus'' (Benedict, 1892) *''Pag ...

Pagurus Acadianus
''Pagurus acadianus'', the Acadian hermit crab, is a species of hermit crab in the family Paguridae. It is found in Western Atlantic Ocean. Distribution The Acadian hermit crab, also known as ''Pagurus acadianus'', can be found in the Western Atlantic Ocean, including areas such as the Vineyard Sound. In addition, the Acadian hermit crab has been cited as the most abundant species of crab in Salisbury Cove, Maine by William C. Grant, Jr, during his extensive study of hermit crabs populating this area in 1961. History ''Pagurus acadianus'' was first identified in scientific literature by scientist J.E. Benedict in 1901. As examined by Morris H. Roberts, Jr.’s, Benedict was able to differentiate this organism from that of a very similar taxa, ''Pagurus benhardus'', due to physical variations. Benedict observed that ''Pagurus acadianus'' had larger eyestalks, shorter fingers of the chelae and sharper chelipeds, all of which are necessary identifiers of the Acadian hermit crab. ...

Pagurus Bernhardus
''Pagurus bernhardus'' is the common marine hermit crab of Europe's Atlantic coasts. It is sometimes referred to as the common hermit crab or soldier crab. Its carapace reaches long, and is found in both rocky and sandy areas, from the Arctic waters of Iceland, Svalbard and Russia as far south as southern Portugal, but its range does not extend as far as the Mediterranean Sea. It can be found in pools on the upper shore and at the mean tide level down to a depth of approximately , with smaller specimens generally found in rock pools around the middle shore and lower shore regions, with larger individuals at depth. ''P. bernhardus'' is an omnivorous detritivore that opportunistically scavenges for carrion, and which can also filter feed when necessary. ''Pagurus bernhardus'' uses shells of a number of gastropod species for protection, including '' Littorina littorea'', '' Littorina obtusata'', ''Nassarius reticulatus'', '' Gibbula umbilicalis'', '' Nucella lapillus'' and ...

Pagurus Longicarpus
''Pagurus longicarpus'', the long-wristed hermit crab, is a common hermit crab found along the Atlantic and Gulf coasts of the United States and the Atlantic coast of Canada.Young, A. M. 1978. Desiccation tolerances for three hermit crab species Clibanarius vittatus (Bosc), Pagurus pollicaris Say and P. longicarpus Say (Decapoda, Anomura) in the North Inlet Estuary, South Carolina, U.S.A. Estuar. Coast. Mar. Sci. 6: 117–122. Description This species of hermit crab can reach a shell length of up to half an inch in size. ''P. longicarpus'' coloration can vary, but body color is most commonly gray, green or white. The right claw of ''P. longicarpus'' is much larger than the left, and each claw has a tan or gray stripe down the middle. The long-wristed hermit crab inhabits the empty shells of gastropods such as periwinkles, snails, and slugs for mobile shelter and protection of their soft abdomens. They anchor themselves into the shells by wrapping their abdomens around the colu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pagurus Armatus
''Pagurus armatus'', the armed hermit crab or black-eyed hermit crab, is a species of hermit crab found in the eastern Pacific Ocean of the United States and British Columbia, Canada. Description ''P. armatus'' is one of the largest species of hermit crab: adults may reach a carapace length of . The legs, including the claws, have bands of colour, in red, orange and white, and the claws bear short spines on the dorsal surface. The eyestalks are short, but bear large black compound eyes. ''P. armatus'' can be told apart from the similar '' P. ochotensis'' by the spines on its claws, which in ''P. ochotensis'' are replaced by granules. The two species are so similar that they have sometimes been considered members of the same species, but are now generally thought to be two distinct species. Ecology ''P. armatus'' lives on a variety of substrates, being particularly abundant in sea pen beds, at depths of up to Type specimen ''P. armatus'' was originally described (under the nam ...
