Clam symmetry

10) A clam has two shells (valves), each with it's own perfect symmetry. The two shells, when compared to each other, look very different. True. Pelecypods have two shells, or bivalves, that protect the soft parts of the animal. The valves are generally of equal size (except in groups like the oysters) and shape and are hinged at the back.
