Cross sectional views through the valves of shelled animals such as brachiopods and bivalves are most common.

Both have bilateral symmetry, as do most groups of animals. Bivalves grow a left and right shell with the line of symmetry along the margins of the valves. Brachiopods grow a front and back (dorsal and ventral) shell, with …Brachiopodsare a phylumof small marineshellfish, sometimes called lampshells.
