They are not closely related to true crabs. Hermit crabs are quite commonly seen in the intertidal zone: for example, in tide pools. Most species have long, soft abdomens which are protected from predators by a salvaged empty seashell carried on the crabs back, into which the crabs whole body can retract. Most frequently hermit crabs use the shells of sea snails; the tip of the hermit crabs abdomen is adapted to clasp strongly onto the columella of the snail shell.
