Biology     Glossary (e.g. epibenthic)

One of the most commercially exploited species in the area. Species is harvested by digging in shallow water. Also collected by recreational fishermen by "treading" (probing with bare feet), and in deeper water by bull rakes and clam tongs. Mechanical harvesting not permitted in Florida. Species is high in protein and virtually fat-free. This species may form hybrids with individuals of M. mercenaria in the southeastern USA (Ref. 344). Lives from the intertidal to the shallow subtidal, in moderately hard sandy bottoms or in sandy mud. Sometimes in close associations with seagrass beds and algae. Rarely found in the surf zone (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).
