Clam symmetry.

Bilaterians are animals that have bilateral symmetry, meaning that they can be divided into equal left and right halves. All animals are bilaterians, with the exception of a few groups of invertebrates such as sponges and cnidarians. Coeloms are lined by the lining of the mesoderm, which is located on the inside of the coelom.Common Fossils of Kansas--Pearl Clams, Oysters, Scallops.

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). Figure 7.10 | Examples of Class Bivalvia. Bivalves feed by sweeping food out of the water column and drawing it through the shell; for most bivalves this food is phytoplankton. Nereis (Clam Worms) is a genus of segmented worms in the family ragworms. They are biodiffusors. They are omnivores. Reproduction is semelparous, gonochoristic, and iteroparous.
