Biology     Glossary (e.g. epibenthic)

Comprise communities and assemblages throughout the Mid-Atlantic Bight (Ref. 80354). Inhabits littoral and sublittoral sediment (Ref. 1314). Found in areas influenced by estuarine outflows (Ref. 96507). Swims backward (Ref. 80328).

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.
