Biology     Glossary (e.g. epibenthic)

Found in sheltered bays, estuaries and lagoons (Ref. 106936). Tends to bury itself in sand, muddy gravel, clay (Ref. 78574) or silty mud (Ref. 107087) and is found on the lower shore and shallow sublittoral (Ref. 78574). Feeds on phytoplankton and detritus (Ref. 107087). 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).
