Clam
A clam's shell consists of two (usually equal) halves, which are connected by a hinge joint and a ligament which can be external or internal.In clams, two adductor muscles contract to close the shells. The clam has no head, and usually has no eyes (scallops are a notable exception), but a clam does have kidneys, a heart, a mouth and an anus. For more information see bivalve and pseudofeces.
