The dorsum surface of these smooth and shiny shells is generally dark brown, with distinct large bluish dots.

In the living cowries the mantle is transparent, with blue sensorial papillae and may cover the entire shell.

This quite common species occurs in the Indian Ocean along Chagos and the Seychelles and in the Pacific Ocean (from South-East Asia, Philippines, Fiji and Micronesia through western Polynesia and Hawaii).

This species lives in tropical shallow water, subtidal and low intertidal, usually under rocks or coral reefs at a minimum depth of about 4 metres (13 ft).

As they fear the light, they start feeding at dusk mainly on sponges or coral polyps.
