Hermit crabs are decapod crustaceans of the superfamily Paguroidea. Most of the 1100 species possess an asymmetrical abdomen which is concealed in an empty gastropod shell that is carried around by the hermit crab.

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, flat-clawed hermit crab, flatclaw hermit crab, shield hermit crab, thumb-clawed hermit crab, broad-clawed hermit crab, and warty hermit crab.
P. pollicaris inhabits the shells of shark eye snails and whelks. It grows to a length of 31 millimetres (1.2 in) and a width of 25 mm (1.0 in). The shell is often shared by the commensal zebra flatworm (Stylochus ellipticus).
The Ecuadorian hermit crab (Coenobita compressus) also known as the Pacific hermit crab is a species of land hermit crab. It is one of the two land hermit crabs commonly sold in North America, including the United States, as a pet, the other being the Caribbean hermit crab (Coenobita clypeatus).
