What are hermit crabs shell made of?

Answer 1

the shells hermies use, are sea snail shells. The snail dies, gets washed up, and at lowtide the hermit crab will remove the snail and ocuppy the shell. If a hermie also sees another hermie with a shell they want, they will fight to the death to get the shell.

Answer 2

The "skin" of a hermit crab, actually its exoskeleton, is made of tough proteins including chitin. The hermit crab's strategy is to scavenge empty shells to use for protection, which become their portable hiding-location and into which they can withdraw if threatened, typically blocking the entrance with one large claw.

Mostly these shells are from dead sea snails, although they sometimes use other hollow objects like shells of bivalves, or hollow rocks or pieces of wood. The main component of marine mollusc shells they choose is calcium carbonate.
