Hermit Crabs

Hermit crabs only have a hard exoskeleton on the appendages and must conceal their soft body parts within empty gastropod shells.  They will exchange shells as they grow and may need to fight other crabs to do so.  They are especially active at night and may be seen by the hundreds in shallow tide pools.
