Mauritia Maculifera
''Mauritia maculifera'', common name : the blotched cowry or reticulated cowry, is a species of sea snail, a cowry, a marine gastropod mollusk in the family (biology), family Cypraeidae, the cowries. Description The shells of these Cowrie, cowries reach on average in length, with a minimum size of and a maximum size of . The dorsum surface of these smooth and shiny shells is generally dark brown, with distinct large bluish dots. On the edges there are large brown spots. The base is white or pale brown or pale pinkish. The aperture is long and narrow, with several dark brown teeth. This species can be distinguished by a characteristic brown columellar spot. In the living cowries the mantle is transparent, with blue sensorial papillae and may cover the entire shell. Distribution This quite common species occurs in the Indian Ocean along Chagos and the Seychelles and in the Pacific Ocean (from South-East Asia, Philippines, Fiji and Micronesia through western Polynesia and Hawai ...

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 ...
