Pagurus pollicaris is a hermit crab commonly found along the Atlantic coast of North America from New Brunswick to the Gulf of Mexico. It is known by a number of common names, including gray hermit crab,[1] flat-clawed hermit crab,[2] flatclaw hermit crab,[1] shield hermit crab,[2] thumb-clawed hermit crab,[3] broad-clawed hermit crab,[4] and warty hermit crab.[5]

P. pollicaris inhabits the shells of shark eye snails and whelks.[4] It grows to a length of 31 millimetres (1.2 in) and a width of 25 mm (1.0 in).[2] The shell is often shared by the commensal zebra flatworm (Stylochus ellipticus).[2]

The diet of the flat-clawed hermit crab comprises organic matter, algae, and sometimes other hermit crabs. Fish are the most important predators of this species.
