Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 7.7 cm DL male/unsexed; (Ref. 83435); common length : 7.0 cm TL male/unsexed; (Ref. 344)

Lives in coarse sand, often near seagrass beds, in shallow subtidal depths (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).
