Description

edit

The shells of these quite uncommon cowries reach on average 38–43 millimetres (1.5–1.7 in) of length, with a minimum size of 23 millimetres (0.91 in) and a maximum size of 57 millimetres (2.2 in). The shape is slender and slightly cylindrical, the dorsum surface is reticulate, smooth and shiny, the basic color is light brown, with beige round spots. Margins are beige too, wide and rounded, with dark brown spots. The base may be whitish, pinkish or purplish, usually with long fine dark brown teeth along a narrow aperture. In the living cowries mantle is dark grey, with clearer sensorial papillae.

Distribution

edit

This species and subspecies range across the Central and East Indian Ocean along East Africa (Red Sea, Somalia, Aldabra, Chagos, the Comores, Kenya, Tanzania, Zanzibar, Madagascar, the Mascarene Basin, Mauritius, Mozambique, Réunion, the Seychelles) and in the West Pacific Ocean (Malaysia, Sulu Sea, Eastern Australia, Philippines, Samar Island, French Polynesia, Oceania, Hawaii).

Habitat

edit

These cowries mainly live on coral reef in tropical subtidal and intertidal waters and in the continental shelf, usually hidden under rocks, coral slabs or small caves during the day, as they start feeding at dusk.
