Where do hermit crabs get their shells?

Question

Like I know they move to bigger shells as they grow. But where do these shells originally come from? Who makes them? How?

If you ever watched SpongeBob, they will wait until someone like Gary passes away and then move into his shell. I believe hermit crabs mostly use snail shells so yeah… they steal Gary’s shell.

Snails have an organ that can produce the material needed to build a shell around them.
