Biology     Glossary (e.g. epibenthic)

Depth range is based on occurrence records in India (Refs. 105071, 105420); to be replaced with a better reference. Found in estuaries on sand (Ref. 105071) and in backwaters (Ref. 105072). Burrows (Ref. 105416). In general, suspension feeding bivalves mainly depend on phytoplankton and detritus material for nutrition (Ref. 107088).

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.
