Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 1.8 cm DL male/unsexed; (Ref. 83435); common length : 2.5 cm TL male/unsexed; (Ref. 344); max. reported age: 2 years (Ref. 8702)
Shell wedge-shaped, inflated. Posterior slope with 2 curved ridges. Surface sculpture consisting of fine radial grooves of microscopic pinpoints. Colour: variable, usually brown, yellowish or purple, with rays of darker hues (Ref. 344).
Assumed total length is 2.5 cm (Ref. 344). Maximum depth from Ref. 104365. Found on beach and shoreline (Ref. 104365). Infaunal in shallow sand, usually in environments rich in particulate organic matter (Ref. 344). 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).
