Mauritia (gastropod)
''Mauritia'' is a genus of sea snails, marine (ocean), marine gastropod molluscs in the family (biology), family Cypraeidae, the cowries. These shelled molluscs are generally exclusive on the island of Mauritius, hence their name ''Mauritia''. Species Species within the genus ''Mauritia'' include: *'' Mauritia arabica'' (Carl Linnaeus, Linnaeus, 10th edition of Systema Naturae, 1758) * † ''Mauritia campbelliana'' (Pilsbry, 1922) *''Mauritia depressa'' (John Edward Gray, Gray) *''Mauritia eglantina'' (Duclos, 1833) *''Mauritia grayana'' Franz Alfred Schilder, Schilder, 1930 *''Mauritia histrio'' (Johann Friedrich Gmelin, Gmelin, 1791) *''Mauritia maculifera'' Franz Alfred Schilder, Schilder, 1932 *''Mauritia mauritiana'' (Carl Linnaeus, Linnaeus, 10th edition of Systema Naturae, 1758) *''Mauritia scurra'' (Johann Friedrich Gmelin, Gmelin, 1791) * † ''Mauritia uzestensis'' Dolin & Lozouet, 2004 ; ; Species brought into synonymy: *''Mauritia mappa'' (Carl Linnaeus, Linnaeus, 1 ...

Gastropod Shell
The gastropod shell is part of the body of many gastropods, including snails, 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, ostracum, is typically made of calcium carbonate (CaCO3) precipitated into an organic matrix ...

Mauritia Depressa
''Mauritia depressa'', common name the "depressed cowry" or the "honey cowry", is a species of sea snail, a cowry, a marine gastropod mollusk in the family (biology), family Cypraeidae, the cowries. Description These quite rare shells reach on average of length, with a maximum size of and a minimum size of . The dorsal color pattern varies from yellowish brown to dark brown, with distinct, almost circular, clear spots. The edges usually are pale bluish or yellowish, with several brown dots. The base is definitely flattened, its colour may be white, pale brown or pale bluish. The teeth along the aperture are dark brown on both lips. Distribution This species occurs in the Central Pacific Ocean and in the Indian Ocean along Chagos, the Comores, Kenya, Madagascar, the Mascarene Basin, Mauritius, Réunion, Tanzania, Lakkadiven Islands, Timor, Philippines and French Polynesia. Habitat These cowries mainly live in shallow water, in coral reefs or in lagoons near the wave-swept e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
