Cowries are known for their beautiful shells.  The snails keep them clean and polished with their mantles, which extend to cover the entire outer surface of the shell. The shells are frequently used in jewelry, and in many parts of the world, cowry shells were once used as currency.

Distribution
Found in the Indopacific, from South Africa and the Red Sea, to Hawaii and French Polynesia.

Habitat
Live in areas of sand and rubble on reef flats and lagoons.

Diet
Cowries scrape algae from rocks and other substrate using their tongue-like radulas.

Quick Fact
Many cowries are nocturnal, and are rarely found out in the open during daylight hours.  Tiger cowries, which are one of the largest cowries, growing 12-15 cm in length, are most commonly found tucked under coral ledges or beneath rubble during the day.
