Bivalvia

Bivalvia (common name bivalves) is a taxonomic class of marine and freshwater molluscs that have a shell in two hinged parts. This class includes clams, oysters, mussels, scallops, and many other families. The name Bivalvia was first used by Linnaeus in 1758, describing the shell, which is composed of two valves. More recently the class was known for a time as Pelecypoda, meaning "axe-foot" based on the soft parts of the animal. Other names which have been used for this class include Lamellibranchia (based on the plate-like gill elements, see ctenidium), Acephala (these animals have no head), and Bivalva (two valves).

At least 18,321 species and subspecies belong to the Class Bivalvia.
