Spisula subtruncata, the Cut Trough Shell, is a medium-sized marine clam, or bivalve mollusc, found in the Eastern Atlantic from Iceland to Morocco and into the Mediterranean Sea. Common and sometimes very numerous. Up to 2.5 centimetres (0.98 in) long, with a distinct triangular shape. This species of clam is found in sandy and silty bottom in the sublittoral zone, where it lives as a sediment-burrowing filter feeder.
