Bivalvia | Veneroida
Environment: milieu / climate zone / depth range / distribution range
Benthic; depth range 5 - 25 m (Ref. 2758). Temperate
Northeast Atlantic and the Mediterranean: from Celtic and Lusitanian provinces, extending into the Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 10.2 cm SHL male/unsexed; (Ref. 360); common length : 7.6 cm SHL male/unsexed; (Ref. 360)
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.
Depth based on occurrence (Ref. 2758, p. 805); to be replaced with better reference. Minimum depth from Ref. 2703. 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).
