Anatomy

A clam's shell consists of two (usually equal) valves, which are connected by a hinge joint and a ligament that can be internal or external. The ligament provides tension to bring the valves apart, whilst one or two adductor muscles can contract to close the valves. Clams also have kidneys, a heart, a mouth, a stomach, and a nervous system. Many have a siphon).
