Bivalves are extremely numerous and varied and there are about 8000 species, mostly in the sea but some in fresh water. Typically the shell is in two pieces with a hinge and closed by strong muscles. Siphons draw water into the large mantle both for respiration and feeding. The class includes clams, mussels, cockles, scallops and oysters.
