Length at first maturity / Size / Weight / Age

Maturity: Lm ?  range ? - ? cm Max length : 7.0 cm ShL male/unsexed; (Ref. )

Biology     Glossary (e.g. epibenthic)

Lives in the swash zone of exposed high-energy intermediate and dissipative sandy beaches. Usually burrows to a depth of around 10 cm, but can reach 25 cm if disturbed. Adults are mainly restricted to the surf zone while most of the juveniles to the swash zone (Ref. 106909). Intertidal to subtidal (Ref. 113820).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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.
