Maximum depth from Ref. 87801. The species is under great pressure from exploitation but the population status is unknown (Ref. 87801). It is an infaunal species, found in intertidal areas to a depth of 65 m, in tide pools, sandy, muddy or pebbly and on mussel banks. Gonochoric species with free-living larvae (Ref. 87801).

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.
