Clam Dissection Guideline BACKGROUND: Clams are bivalves, meaning that they have shells consisting of two halves, or valves.The valves are joined at the top, and the adductor muscles on each side hold the shell closed. If the adductor muscles are relaxed, the shell is pulled open by ligaments located on each side of the umbo.The clam's foot is used to dig down into the
