Monetaria moneta, commonly known as the money cowry, is a species of small sea snail, a marine gastropod mollusk in the family Cypraeidae, the cowries. [1]

The species is called money cowry because the shells were historically widely used in many Pacific and Indian Ocean countries as a form of exchange[3] before coinage was in common usage. It is still used in divination rituals by some African animist tribes.[3]

Distribution

A distribution map of Monetaria moneta

This is a very common species which is found widely in Indo-Pacific tropical waters. It is present in numerous regions, including East and South Africa, Madagascar, the Red Sea and the Persian Gulf, eastern Polynesia, Galapagos, Clipperton and Cocos islands off Central America, southern Japan, Midway and Hawaii, and northern New South Wales and Lord Howe Island.[3]

Habitat

An individual of Monetaria moneta in situ, with its mantle completely expanded.

This cowry lives in intertidal rocky areas and shallow tide pools among sea weed, coral remains and empty bivalve shells[3]. It can be found on and under rocks in shallow water and on exposed reefs at low tide. Like all cowries, it feeds on algae and marine vegetation growing on loose rocks and pieces of dead coral.

Shell description

Dorsal view of two shells of Monetaria moneta

The shell is small (30 to 45 mm long[3]). It is white to straw-colored, and sometimes has a gold-colored ring around the dorsal area similar to the gold ring found on the shell of Cypraea annulus (gold-ringed cowry).

Human uses

Shells of this cowry were commonly used as a medium of exchange in many areas of Africa, Asia and the Pacific islands until the late 19th century.It was also traded to Native Americans by European settlers.

The shell continues to be popular today in jewelry and for decoration of such items as baskets and wall hangings.
