DescriptionMollusc shells display an infinite variety of colours, patterns, shapes, and sculpturing. The shell is secreted by a specialized area of the animal’s upper surface known as the mantle. The long and delicate spines representative of this venus clam are secreted by minute, long, fleshy outgrowths of the mantle edge. These spines serve as anchors to prevent intertidal waves from washing the clams out of the sand in which they live. Its valves reach a length of about 5 cm and the spines may be half that size. This clam occurs from Baja California to Peru while an almost identical Atlantic form lives in the West Indies. It is a common species and can be found intertidally on beaches to a depth of 3 metres.
