Cypraea Mappa
''Leporicypraea mappa'' (previously known as ''Cypraea mappa''), common name the map cowry, is a species of large sea snail, a cowry, a marine (ocean), marine gastropod mollusk in the family Cypraeidae, the cowries. This is considered an economy, economically important species in the Indo-West Pacific, where it is usually collected both for food and for shell trading.Poutiers, J. M.

The map cowry was named on the basis of its distinct color pattern, because of the longitudinal lines and the easily distinguishable and sinuous mantle (mollusc), mantle groove, which creates a resemblance to ancient maps. Taxonomy ''Leporicypraea mappa'' was previously subordinated into the genus ''Cypraea''. In the currently m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mantle (mollusc)
The mantle (also known by the Latin word pallium meaning mantle, robe or cloak, adjective pallial) is a significant part of the anatomy of molluscs: it is the dorsal body wall which covers the visceral mass and usually protrudes in the form of flaps well beyond the visceral mass itself. In many species of molluscs the epidermis of the mantle secretes calcium carbonate and conchiolin, and creates a shell. In sea slugs there is a progressive loss of the shell and the mantle becomes the dorsal surface of the animal. The words mantle and pallium both originally meant cloak or cape, see mantle (vesture). This anatomical structure in molluscs often resembles a cloak because in many groups the edges of the mantle, usually referred to as the ''mantle margin'', extend far beyond the main part of the body, forming flaps, double-layered structures which have been adapted for many different uses, including for example, the siphon.
