Family: Cardiidae (Cockles)


Description
The family Cardiidae is one of the largest and best-known of bivalves. There are over 200 living cockle species and many more fossil forms.
 
Strong, compact, and heart-shaped, the cockle shell can be rolled over the sands and banged about without any damage to the live mollusc. Its siphons are short, and the foot is also well developed --indeed capable of moving the animal about in short leaps at the surface, where it normally lives. In many cockles, the siphons also bear light receptors.
 
Shell features are: completely symmetrical and equal sized valves; prominent umbones; strong radial ribs, which in some species carry spines; equal size muscle scars; no pallial sinus; and, two cardinal teeth in each valve. The internal margin of the lip may vary from lightly serrated to the definitely crenulated edge view, shown in the two species at right.
