The prickly cockle was one of the many invertebrate species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, where it was given the binomial name Cardium echinatum.[4]
The yellowish-brown shell is up to 75 mm in diameter, and is adorned by 18 to 22 spiny ridges. Its margin is crenulate and its inner surface is white, and also prominently grooved.[2]
The prickly cockle is found in the British Isles and northwestern Europe. It lives within a few centimetres of the sea bottom, at depths of 3 m or more. Dead shells are commonly washed up on the beach.[2]
