Short description Morphology

Shell relatively thin but solid, inflated, inequilateral, roughly quadrate to subtrigonal in shape, with a rounded umbono-ventral keel and an obliquely truncated posterior margin; slightly inequivalve, left valve somewhat projecting beyond right along posterior and ventral margins. Umbones subcentral, prominent, on top of a well-developed trigonal cardinal area which is engraved by oblique, chevron-shaped grooves and covered with a black external ligament. Outer sculpture of numerous radial riblets and concentric threads forming a fine reticulation. Periostracum conspicuous, velvety. Hinge elongate, straightish dorsally and weakly arched ventrally, bearing a series of transverse, diverging outward teeth, and rather long, subhorizontal teeth at both ends, at least in adults. Interior of shell porcelaneous. Two subequal adductor muscle scars; inner margin of posterior scar on a projecting shelf. Pallial line without a sinus. Internal margins with a fine crenulation becoming obsolete in old individuals. Colour: outside of shell purple tan, with a yellowish periostracum. Inner side white, more or less strongly tinged with dark reddish brown posteriorly.

Biology     Glossary (e.g. epibenthic)

On sandy to muddy bottoms offshore (Ref. 348). 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).
