The second largest class of molluscs, contains about 10,000 species including the clams, mussels, oysters and scallops. About one-third live in fresh water, with the rest being marine. They are generally filter feeders, with most species living on microscopic plant life. Most bivalves shed their eggs directly into the water, but a few brood their young in gill pouches.
