Cypraea Ficoides
''Cypraea'' is a genus of medium-sized to large sea snails or cowries, marine gastropod mollusks in the family Cypraeidae, the cowries. Species Species within the genus ''Cypraea'' include: * † '' Cypraea ficoides'' (Hutton, 1873) * '' Cypraea pantherina'' Lightfoot, 1786 * † ''Cypraea porcellus'' Brocchi, 1814 * ''Cypraea tigris'' Linnaeus, 1758 ;Nomen dubium: * ''Cypraea contrastriata'' Perry, 1811 (synonyms: ''Arestorides argus contrastriata'' (Perry, 1811); ''Cypraea argus contrastriata'' Perry, 1811; ''Talparia argus contrastriata'' (Perry, 1811) ) Synonyms Almost all species previously belonging to ''Cypraea'' have been reassigned to other genera within the family Cypraeidae: * ''Cypraea achatidea'' Sowerby, 1837: synonym of '' Schilderia achatidea'' * ''Cypraea acicularis'' Gmelin, 1791: synonym of '' Erosaria acicularis'' * ''Cypraea aenigma'' Lorenz, 2002: synonym of '' Nesiocypraea aenigma'' * ''Cypraea albuginosa'' Gray, 1825: synonym of '' Erosaria albuginos ...

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 ...
