Bivalve shell

High Quality Content by WIKIPEDIA articles! A bivalve shell is part of the body, the exoskeleton or shell, of a bivalve mollusk. In life, the shell of this class of mollusks is composed of two parts, two valves which are hinged together. Bivalves are very common in many kinds of saltwater habitats, but they are also found in brackish water and in freshwater. Bivalves are a common part of the marine fauna worldwide scallops, clams, oysters, mussels, etc. The shells of marine bivalves commonly wash up on beaches often as separate valves and the shells of freshwater species can sometimes be found along the flood plains of rivers, and other freshwater habitats. Bivalves typically have two-part shells, two valves, that are joined by a ligament. The two valves usually articulate with one another using structures known as "teeth" which are situated along the hinge line. In many (but by no means all) bivalve shells, the two valves are symmetrical along the hinge line.
