Common Edible Cockle Cerastoderma edule

The common edible cockle is a bivalve that has a robust, ribbed shell and burrows in dense populations just below the surface of sand or mud, filtering organic matter such as plankton from the water. Free-swimming larvae emerge from its fertilized eggs. Adult common edible cockles sink to the sea floor, where they assume a more sedentary lifestyle.
