Maturity: Lm 10.0  range ? - ? cm Max length : 24.9 cm DL male/unsexed; (Ref. 83435)

Biology     Glossary (e.g. epibenthic)

Maximum depth from Ref. 104440. Intertidal (Ref. 106829) to subtidal (Ref. 101477). Found in sand flats (Ref. 101477). Carnivorous. Forages on intertidal flats and creeks fringed by oyster reef and in subtidal channels (Ref. 106829). Preys on bivalves (Refs. 101524, 101525) such as oysters, scallops and clams (Ref. 106829). It uses the lip of its shell, synchronous with its foot, to penetrate, break off and force open the valves of its prey (Refs. 101524, 101525).

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

Broadcast spawners. Life cycle: Embryos emerged into miniature adults which further develop into grown adults (Ref. 833).
