hermit Crabs - superfamily decapods from infra Anomura, use as a permanent shelter empty shells of mollusks. In addition to the mechanical protection, the original home of these animals provides resistance to dry environments.



during adolescence hermit crabs are forced to change the shell on larger, while in some species the molting process begins only after selecting a new home. However, many arthropods of this group live in a beneficial symbiosis with coral polyps, undigested, which serve as a kind of protection from enemies, instead of getting access to the remains of food.
