Short description

Shell rather thick and large (attaining 30 cm in length), subcircular in outline, with a short and ill-defined posterior ear which is not drawn out into a wing-like process. Anterior margin markedly protruding beyond the tip of anterior ear. Outer surface of valves, when not worn, covered with flattened, imbricating concentric scales bearing large and irregular, flat spines with blunt ends, roughly arranged in radial rows and projecting at shell margins. Hinge completely devoid of teeth. Colour: outside of shell uniformly fawn, sometimes with radial stripes of darker spots in umbonal region; then, ground colour in that region green, dark brown, or purple. Internal nacreous area highly lustrous, silvery with a variably extended golden border. Non-nacreous margin clear, of plain horny colour.

Biology     Glossary (e.g. epibenthic)

Mainly in clear water under the influence of currents. Often in dense colonies. Littoral and sublittoral to a depth of 60 m; most common from sublittoral at depths of 5 to 30 m (Ref. 348). On various bottoms, byssally attached to hard substrates at least in the young stages (Ref. 348). Inhabits a broad range of habitat, from sand, mud, gravel, seagrass beds, deepwater reefs, to near sponges, soft corals or whip corals. Filter-feeder (Ref. 101206). Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites. Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833).
