Erosaria Miliaris
''Naria miliaris'', common name the millet cowry or the inocellate cowry or the military 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 very common cowries reach on average of length, with a minimum size of and a maximum size of . The dorsum surface of these smooth and shiny shells is generally pale brown or yellowish, with several small white spots. The base is white or pink, with several fine teeth. In the living cowries the mantle is pale brown and greyish, with long tree-shaped sensorial papillae. This species is quite similar to ''Naria lamarckii,'' but in ''Naria miliaris'' the edges of the shell are white, without any spots. Distribution This species is distributed in the Indian Ocean along Madagascar and Tanzania and in the western Pacific Ocean to Australia, along Japan, East China, Taiwan, Vietnam, East Thailand, East Malaysia, Flores, North Borneo, Jav ...

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 ...
