Any aquatic mollusk belonging to the class Pelecypoda (phylum Mollusca), which includes clams, mussels, scallops, and oysters. Pelecypods have two symmetrical calcareous shells, called right and left valves, that are joined by a hinge. Pelecypods are also known as bivalves because of this bilateral symmetry.
