Description
The family Veneridae has over 400 living species. It is one of the most colorful of the bivalve groups. Shape varies from circular to triangular, and from side view will appear as either ovate (egg-shaped) or cardioid (heart shaped) shells. Characterististics are: porcelain-like shell that is highly finished; a complex tooth structure in the hinge; a well developed escutchion and lunule; and, a well developed sinus at the pallial line. Spiny forms are comparatively uncommon in this family (See Pitar lupanaria below).
A folded gill structure that is extensively developed for filtering out small food particles is typical of this and other families in the Veneroida order.
