Symmetry of a clam
anyway back to the beach. Bilateral symmetry can be easily found on shells if you are lucky enough to find any type of clam style shell that is still attached to its other half. These are often referred to as 'Bi-Valve'; having two halves. Many leaves will show a tendency towards bilateral symmetry because of the presence of a mid vein.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. Clams have bilateral symmetry. Clams, like most mollusks, also have open circulatory systems, which means that their organs are surrounded by watery blood that contains nutrients and oxygen.
