Note: this image is colored to differentiate internal organs and are not the actual colors of the clam. Clams are filter feeders. Clams characteristically lie buried from just beneath the surface to depths of about 0.6 metre (2 feet). They rarely travel over the bottom as do some other bivalves. Most clams inhabit shallow waters, in which they are generally protected from wave action by the surrounding bottom. Clam. Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. [1]

Clam Anatomy Diagram anatomy diagram source
Clams are marine mollusks with two valves or shells. Like all mollusks, a clam has a mantle which surrounds its soft body. It also has a muscular foot which enables the clam to burrow itself in mud or sand. The soft tissue above the foot is called the visceral mass and contains the clam's body organs. Taxonomy Kingdom - Animalia Phylum - Mollusca Hard Calm or Northern Quahog. Anatomy
. 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.

The phylum Mollusca includes snails, clams, chitons, slugs, limpets, octopi, and squid. As mollusks develop from a fertilized egg to an adult, most pass through a larval stage called the trocophore. The trocophore is a ciliated, free-swimming stage. Mollusks also have a radula or file-like organ for feeding, a.
