As with all mollusks, gastropods are characterized by having a true coelom, a fluid-filled and fully-lined body cavity; a body divided into the three parts of head, visceral mass, and muscular foot; and organ systems for circulation, respiration, digestion, excretion, nerve conduction, and reproduction (Towle 1989).

The body consists of head and torso. Foot highly modified into a funnel — conical tube leading into the mantle cavity, where the clams swim. Around the mouth the crown is situated tentacles, or arms, which are lined with several rows of suction cups are strong and have powerful muscles.
