Life cycle and mating behavior
Könsmognad | Reproduktion | Lek | 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 (Ref. 833).
