These saltwater clams are sedentary and live intertidally and in shallow subtidal areas of sand flats on the east coast of the U.S. The morphology and anatomy of modern bivalves have been much altered from those of ancestral mollusks, which had a distinct anterior end with a mouth and a posterior end with an anus (Figure 1).Bivalves. Bivalves are molluscs with bodies that are enclosed in a shell of two halves (valves) that can be opened at one end. The animal pumps water in and out of the shell. This water brings dissolved oxygen for the animal to breathe with gills and, in most species, food particles. Bivalves can be found in fresh water or saltwater environments.
