Clam

Clam

Clam, in general, any member of the invertebrate class Bivalvia—mollusks with a bivalved shell (i.e., one with two separate sections). More than 15,000 living species of bivalves are known, of which about 500 live in fresh water; the others occur in all seas. Bivalves usually live on or in sandy or muddy bottoms.
True clams, in the strict sense, are bivalves with equal shells closed by two adductor muscles situated at opposite ends of the shell, and with a powerful, muscular, burrowing foot. Clams characteristically lie buried from just beneath the surface to depths of about 0.6 m (2 feet). They rarely travel over the bottom as do some other bivalves.
