Hermit crab species range in size and shape, from species only a few millimeters long to Coenobita brevimanus (Indos Crab), which can approach the size of a coconut and live 12–70 years. The shell-less hermit crab Birgus latro (coconut crab) is the world's largest terrestrial invertebrate.
A Caribbean hermit crab in the Dry Tortugas National Park, Florida. The Caribbean hermit crab (Coenobita clypeatus), also known as the soldier crab, [2] West Atlantic crab, tree crab, or purple pincher (due to the distinctive purple claw), is a species of land hermit crab native to the west Atlantic, Belize, southern Florida, [3] Venezuela, and the West Indies.
Pagurus samuelis is a small hermit crab, at up to a total length of 40 mm (1.6 in) and a carapace width of up to 19 mm (0.75 in). [2] The base colour of the exoskeleton is brown or green, [2] but the antennae are red, and adults have bright blue bands near the tips of their legs. [3]
The red reef hermit crab is a scavenger, feeding on animal and vegetable detritus. The sexes are separate in this species and it breeds throughout the year. The eggs are orange and hatch into planktonic larvae. When these settle on the seabed, the juvenile hermit crabs need to search for a suitable shell to occupy.
Unlike other hermit crabs, pylochelid hermit crabs are not markedly asymmetrical, with a straight body and equal numbers of appendages on both sides. This characteristic, together with the partial calcification of the abdomen (which is soft in other hermit crabs) led Edward J. Miers, when describing the first species, to consider it to represent a transition between hermit crabs and "Macrura ...
The Acadian hermit crab, also known as Pagurus acadianus, can be found in the Western Atlantic Ocean, including areas such as the Vineyard Sound. [5] 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.
The specimens collected were sent to London where this hermit crab was first described in 1839 by the English naturalist Richard Owen, curator of the Museum of the Royal College of Surgeons. [3] He named it Pagurus splendescens , [ 1 ] becoming Labidochirus splendescens in the seventies when the subgenus Labidochirus , of which it was the type ...
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.
