Linnaeus, 1758 
The valves of the shell are elongated and reach a length of up to twenty-one centimetres (8.3 in). The two sides are straight and parallel. The colour is creamy white, sometimes with brownish stripes, and the periostracum is olive green. It is sculptured with fine lines and growth marks can be seen. The anterior end is truncated while the posterior end is rounded. It has a very large foot and is capable of burrowing in the fine, hard-packed muddy sediments that it favours. where it is associated with the starfish (Astropecten irregularis) and the common otter shell (Lutraria lutraria).
