sea shell
Mollusk's former home
A sea shell is the hard outer covering of a marine mollusk—a snail, clam, oyster, or similar creature.
Beachcombers collect them; children hold them to their ears to "hear the ocean." The term applies whether the shell still houses its animal or lies empty on the shore.
Also spelled seashell.
