Biology     Glossary (e.g. epibenthic)

Collected for food and for the large, heavy shell in many areas. Mature shell is traditionally used as a trumpet when the tip of the spire is cut off (Ref. 349). Common on inner reef flats and in shallow water near rocky areas, but frequent also offshore. Occurs at the low tide mark. Fasciolariidae are active predators, feeding on tube worms, vermetid and other molluscs (Ref. 349). Members of the order Neogastropoda 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).
