Hermit Crabs are crustaceans like crabs and lobsters, however they have a soft very vulnerable body that is somewhat coiled upo itself. To protect this soft body from predators or any other threat, they use a hard shell. They can also retreat completely into this shell, which also helps predators from being able to pry them out.
