Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 10.0 cm SL male/unsexed; (Ref. )
Minimum depth range from Ref. 356. Found in nearshore waters and in shallow subtidal zone (Ref. 106914). This is an epifaunal species found on soft sandy and muddy bottoms, as well as hard substrates. It is a brooding species where females retain the larvae until they are completely developed (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 (Ref. 833).
