Evolution on the Half Shell...

The egg cockle’s powerful foot allows it to bury rapidly in the sand or move by short leaps or swim for short distances to evade predators, such as starfish and seabirds. Heart cockles are fished in many parts of the world for human consumption, and are often of substantial economic importance. The common name “heart cockle” refers to the shell outline in anterior view (a lateral view is shown here). A recent scientific study has shown that Giant Clams also belong to this family, though their “upside-down” anatomy, symbiotic algae, and sessile habits make them unusual and unique members.
