The Cockle lives in sand and mud in shallow water, often in brackish inlets. It burrows until only the siphons project, pulling in water from which the animal strains the minute planktonic organisms on which it feeds
The large powerful muscular foot is bent backward beneath the shell and then straightened to accomplish the characteristic jumping form of forward locomotion.
In most adults, the foot is about as long as the greatest length of the shell.
