The soft parts quickly decay, and the shells are scattered over the sea floor. 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.17 Apr 2021 ...
