Shell: solid, convex valves, equivalve and inequilateral, roughly oval in shape, uniformly deep yellow brown in color; sculpture consists of 20-22 well-developed ribs, with triangular spikes along the mid-line, in between are very marked concentric grooves; external ligament behind the umbones, hinge is heterodont; inside the valves are two identical scars (dimyarian and isomyarian) joined by a continuous pallial line, lacking a sinus. Body: foot is roughly cylindrical, well developed and used for leaping on the sand; distal extremity is bright red.

Life cycle and mating behavior

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.
