The Common Cockle, Edible Cockle, scientifically known as Cerastoderma edule, is a species of saltwater clam that is widely distributed throughout coastal regions of Europe. This edible bivalve is a popular seafood choice and is often found in shallow waters along coastlines.

Description & Characteristics

Cerastoderma edule is a medium-sized clam, typically reaching a maximum size of around 5 centimeters in length. Its shell is heart-shaped, with a distinctive pointed apex. The shell’s color can vary depending on the environment, ranging from white to yellowish-brown, often with a reddish-brown tinge. The exterior of the shell is usually rough, featuring prominent ribs and grooves. It is considered a common species and can be easily identified by its distinct characteristics.

Habitat and Occurrence

The Common Cockle, Edible Cockle is a common inhabitant of intertidal and subtidal zones along the coasts of Europe, specifically the North Sea, the Baltic Sea, and the Atlantic coast of France. Cerastoderma edule prefers to inhabit sandy or muddy bottoms, often congregating in dense beds. It thrives in areas with moderate wave action and salinity. It is generally found in depths ranging from the intertidal zone to approximately 20 meters below the surface. It is particularly prevalent in the neritic zone, a marine environment characterized by relatively shallow waters and a diverse range of organisms.

Taxonomy

The Common Cockle, Edible Cockle, Cerastoderma edule, belongs to the Class Bivalvia, a group of mollusks with two shells hinged together. It is classified within the Order Cardiida, an order characterized by heart-shaped shells, and further grouped under the Family Cardiidae, commonly known as cockle shells.

Feeding

Cerastoderma edule is a filter feeder, meaning it extracts food particles from the water. It feeds on a variety of organisms, including phytoplankton, algae, and organic detritus. It uses its gills to filter out small particles, which are then transported to its mouth. This feeding strategy makes the Common Cockle, Edible Cockle an important part of the marine ecosystem, playing a role in the food chain and nutrient cycling.
