Coelomate. Class Bivalvia ranges from Lower Cambrian to today, and peaked in the Cenozoic. Bivalve animals are typically encased in two shells—also called valves—hence the name bivalve. The shells have bilateral symmetry from top to bottom (the two shells look the same), rather than the side-to-side symmetry of the brachiopods (Figure 7.10).This is true of most clams. Brachiopods are quite different. Inasmuch as their valves are seldom similar, the plane of symmetry that divides the animal into mirror-image halves passes vertically down the middle of each valve (left drawing, "Bilateral symmetry (brachiopod)"), and is perpendicular to the line along which the valves join.Brachiopods and mollusks are in different phyla (large divisions of life) because they have different body symmetries and internal structures.

Bivalves usually live on or in sandy or * Clams provide a food source and pearls. Digestive System. * Food enters the clam through lip-like structures called labial palps and goes into the mouth. Food ...Radial Symmetry. Another trait that evolved early on was symmetry. To understand symmetry, you need to see an animal that lacks symmetry. A sponge, like the one in Figure below, lacks symmetry. This means it cannot be divided into two identical halves. A symmetrical organism, in contrast, can be divided into two identical halves. The line drawing below is helpful in illustrating the differences in symmetry between pelecypods and brachiopods.
