Map Cowrie

Overview

The Map Cowrie (Leporicypraea mappa) is a striking marine gastropod widely recognized for the intricate, map-like patterns on its shell. This large sea snail is highly valued in the Indo-Pacific region, where it has historically been collected for both food and the shell trade.

Distribution & habitat

This species is widely distributed throughout the Indo-Pacific, including the Red Sea, East Africa, Madagascar, southern Japan, Australia, New Caledonia, and eastern Polynesia. It typically inhabits coral reef environments, where it can be found in both shallow and deeper waters, often hiding in rock crevices or beneath coral plates.

Appearance

The shell is thick and humped, generally reaching lengths of 60 to 90 mm, though some individuals may grow up to 100 mm. Its dorsal surface is typically cream-colored with brown patches and distinct longitudinal lines that resemble ancient cartography. A characteristic sinuous mantle groove runs along the shell, and the base is usually creamy with orange-tinted, coarse, blunt teeth. The margins are often thickened and mushroom-colored, marked with smudged brown spots. Many populations also exhibit a unique red fluorescence when viewed under longwave ultraviolet light.
