Mauritia Histrio
''Mauritia histrio'', common name the harlequin cowry or the stage cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family (biology), family Cypraeidae, the cowries. Description These quite common large shell reach on average of length, with a maximum size of and a minimum adult size of . The basic color of the shell is pale brown, with many grey round spots on the dorsum surface and several dark brown marginal spots on the edges. The base is mainly white or pale brown, with a wide aperture and well-developed darker teeth, longer and stronger on the outer side. In the living mollusk the mantle is transparent, with short papillae. ''Mauritia histrio'' is quite similar to ''Cypraea arabica'' and ''Mauritia eglantina''. Distribution This species is distributed in the Indian Ocean and Western Pacific Ocean, along Aldabra, Chagos, East Africa, Kenya, Madagascar, the Mascarene Basin, Mauritius, Mozambique, Réunion, the Seychelles, Tanzania, North We ...

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...
