They don't...their shells grow with them. Only hermit crabs get brand new shells. Everything else either molts or has a shell that grows with the body.

umm, excuse me? Snails are born with their shells, and their shells grow with them throughout their lives. They're kinda connected on the inside

Because they outgrow their old shells.
