Cowrie
Summary
Cowrie or cowry () is the common name for a group of small to large sea snails, marine gastropod mollusks in the family Cypraeidae, the cowries.
The term porcelain derives from the old Italian term for the cowrie shell (porcellana) due to their similar appearance.
The cowrie was the shell most widely used worldwide as shell money. It is most abundant in the Indian Ocean, and was collected in the Maldive Islands, in Sri Lanka, along the Indian Malabar coast, in Borneo and on other East Indian islands, in Maluku in the Pacific, and in various parts of the African coast from Ras Hafun to Mozambique. Cowrie shell money was important in the trade networks of Africa, South Asia, and East Asia.
In the United States and Mexico, cowrie species inhabit the waters off Central California to Baja California (the chestnut cowrie is the only cowrie species native to the eastern Pacific Ocean off the coast of the United States; further south, off the coast of Mexico, Central America and Peru, Little Deer Cowrie habitat can be found; and further into the Pacific from Central America, the Pacific habitat range of Money Cowrie can be reached) as well as the waters south of the Southeastern United States.
Some species in the family Ovulidae are also often referred to as cowries. In the British Isles the local Trivia species (family Triviidae, species Trivia monacha and Trivia arctica) are sometimes called cowries. The Ovulidae and the Triviidae are other families within Cypraeoidea, the superfamily of cowries and their close relatives.
The word cowrie comes from Kiswahili Kauri (meaning ceramic/porcelain), Hindi कौडि (kaudi), from Tamil கவடி ("kavadi"), , from Malayalam കവടി ("kavadi"), which has its origins in Sanskrit कपर्द (kaparda).
The shells of cowries are usually smooth and shiny and more or less egg-shaped. The round side of the shell is called the Dorsal Face, whereas the flat under side is called the Ventral Face, which shows a long, narrow, slit-like opening (aperture), which is often toothed at the edges.
