Biology     Glossary (e.g. epibenthic)

Half-buried in sand and gravel bottoms under the influence of currents, with the twisted posterior end of shell lying horizontally on the surface. The posterior surface of the left valve, which slightly projects above the sand surface, is often extensively eroded or damaged and colonized by other sessile organisms. Juvenile specimens are byssally attached inside empty shells of the species and other bivalves, to ensure protection against predators and water movement (Ref. 348).

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.
