Clams are bivalve mollusks, which means they have a two-part shell that is hinged together. The shell is made up of two valves, which are connected by a hinge ligament. Clams have a muscular foot that they use for burrowing into the sand or mud. They also have two siphons: one for drawing in water and food, and the other for expelling waste.

Inside the shell, clams have a soft body that contains their organs. They have a heart, a mouth, and adductor muscles that allow them to open and close their shells. Clams also have a burrowing foot that they use to move through the sand or mud.
