Biology     Glossary (e.g. epibenthic)

Actively collected by native populations for food, by hand at low tide on the reefs, or by diving. In spite of its weight and considerable size, the shell is favored, especially by tourists, due to the beauty of its heavily glazed aperture (Ref. 349). Found in shallow lagoons to the outer edge of reefs. Shell of old specimens often worn and encrusted with calcareous algae, vermetid snails, and tubes of polychaete worms (Ref. 349). Members of the genus Lambis are specialized herbivores, feeding on macroscopic or unicellular algae and algal detritus (Ref. 107011). Members of the order Neotaenioglossa are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults (Ref. 833).
