Bivalvia (bivalves and clams)

Wikipedia Abstract

The Bivalvia, in previous centuries referred to as the Lamellibranchiata and Pelecypoda, comprise a class of marine and freshwater molluscs that have laterally compressed bodies enclosed by a shell consisting of two hinged parts. They have no head, and they also lack a radula. Bivalves include clams, oysters, cockles, mussels, scallops, and numerous other families that live in saltwater, as well as a number of families that live in freshwater. The majority are filter feeders.
