Clams obviously live in the clam shells, sea slugs live in the spirial shells. Some of their organs actually form inside the shell. Also, once those die, sometimes hermit crabs take over the shell when they out grow their previous shell.
crabs, mollusks, oysters, mussels, clams, scallops, and other creatures
Usual marine life that live in shells are creatures that need protection from predators because of their soft bodies. Things like snails, slugs, clams, and mussels are just a few of the creatures that live in shells or have some sort of hard shell like armor on their bodies.
If by shell you mean a detachable exoskeleton, most crustaceans have a shell in the ocean.

No it is a reptile you can tell this because it lives on land not in the sea but a turtle lives in the sea they are not the same animal although they are very closely related and have almost the same name. So in a nut shell no because a tortoise goes on land and a turtle goes in the sea! from AstonDB9
