Short description বহিঃ অঙ্গ সংস্থান

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.

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

Life cycle and mating behavior পরিপক্কতা | প্রজনন | ডিম ছাড়া | Eggs | ডিম্বধারন ক্ষমতা | Larvae

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.
