Biology     Glossary (e.g. epibenthic)

Actively collected and often over fished, or commercially cultured for the shells which are used in large quantities for shellcraft. Transparent shells are locally used in some areas as a substitute for window glass in houses. Soft parts are consumed by coastal populations (Ref. 348). Found in sandy or muddy substrates in shallow estuarine lagoons, coves and small bays where salinity of water ranges from 10-35 ppm (Ref. 80041). Also found on seagrass (Ref. 122159). 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).
