Physical Characteristics:
Bivalvia (common name bivalves) is a taxonomic class of marine and freshwater molluscs. This class includes clams, oysters, mussels, scallops, and many other families of molluscs that have two hinged shells. The class was known for some time as Pelecypoda, which is a reference to the soft parts of the animal, whereas the name Bivalvia simply describes the shell, which has two valves. Other names which have been used for this class include Lamellibranchia (referring to the plate-like gill elements, see ctenidium), Acephala (they have no head), and Bivalva (two valves).
