These cowries live in tropical shallow water, subtidal and intertidal, usually under rocks or corals up to about 10 metres (33 ft)of depth. They start feeding at dusk, mainly on sponges. This species occurs in the Red Sea, in the Indian Ocean along South-East Africa (Aldabra, Chagos, Kenya, Madagascar, the Mascarene Basin, Mauritius, Réunion, the Seychelles, Zanzibar and Tanzania) and in the western Pacific Ocean (Philippines, Japan, Taiwan, western and northern Australia, Polynesia and Hawaii).
