OYSTER

n. any of various edible bivalve mollusks that are found mainly in shallow waters and are generally eaten raw; dark piece of meat found in the hollow of the pelvic bone of a fowl; non-talkative or secretive person (Informal)

The common name oyster is used for a number of different groups of bivalve mollusks, most of which live in marine or brackish water. The shell consists of two usually highly calcified valves which surround a soft body. Gills filter plankton from the water, and strong adductor muscles are used to hold the shell closed.
