Minimum depth from Ref. 104365. Lives in sand, from the intertidal to very shallow subtidal (Refs. 344, 114796). Shallowly buried in sandy bottoms (Ref. 114795). Abundant near river mouths where organic matter and terrigenous particulates accumulate (Ref. 114796). Suspension feeder (Ref. 78149).

Life cycle and mating behavior Γεννητική Ωρίμανση | Αναπαραγωγή | Γεννοβολία | Eggs | Γονιμότητα | 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.
