Easily mistaken species

There are a number of cockle specie in Sweden, about 8 or 9, but the most common shell that is found on the beach comes from the Common cockle. On clayey bottoms and where the water has a low saline content, e.g. The Baltic and estuaral areas, the similar looking species,Cerastoderma lamarcki is found. The warped shell has a more slender locking valve edge and the internal rib grooves are longer than with the Common cockle.
