Extensively used for food, shell jewelry, inlay, and button making. It is the most important commercial species of Turbinidae in the tropical Indo-West Pacific. Intensive fishing for the mother-of-pearl trade has drastically reduced many turban populations in recent years. In order to protect existing resources and to increase the possibilities of long-term exploitations, attempts of juvenile production, reintroduction, translocation, and commercial legislation are under way in the area (Ref. 349). Maximum depth from Ref. 75835. In subtidal, coral reef areas open to a constant flow of clean oceanic water. Juveniles mainly living on reef crests; adults also occurring deeper on slopes to about 20 m or more (Ref. 349). Found at depths of 10 to 30 m, on rocks (Ref. 75835). Primarily herbivorous, with few small animals eaten that are associated with the assemblage of algae (Ref. 105749).

Members of the order Patellogastropoda are mostly gonochoric and broadcast spawners. Life cycle: Embryos develop into planktonic trocophore larvae and later into juvenile veligers before becoming fully grown adults.
