A cockle's large, muscular foot juts through an opening in the mantle supporting its shell.

The cockle bends and straightens the foot to jump away from predators in its shallow-water ocean habitat off the island of Espiritu Santo, Vanuatu. The cockle uses the two small holes in its shell to pump and release seawater filtered through its gills.
