Answer and Explanation: 1. The valves of a clam are the two cupped shells that form the clams hard outer covering These shells are joined by a single ligament.

Unlike chitons, bivalves are laterally flattened.Clams are bivalves meaning 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.

Bivalve - Gills, Filter Feeding, Mantle: Primitive bivalves have paired gills that are small; in most other bivalves the gills are greatly enlarged. The vascular system contains the heart comprising a medial ventricle with left and right auricles. The reproductive system is simple. The most significant adaptation is the shell with two valves that wholly contains the animal.
