Minolia Shimajiriensis
''Minolia'' is a genus of sea snails, marine gastropod mollusks in the family Solariellidae. A. Adams named the genus from Mino-Sima, the little island near Niphon (Japan). ''Minolia'' was in older textbooks regarded as a subgenus of ''Margarita'' Leach, 1819 (itself now a synonym of ''Margarites'' Gray, 1847). Description The thin, delicate, smooth shell is depressed and widely umbilicated. The whorls are rounded or angulated. The spire is depressed. The sculpture is finely decussated. The aperture is circular. The outer lip and columella thin, simple, acute. The umbilicus is simple and contains no spiral, callous internal funicle or rib. Distribution These marine species belong to the Indian Ocean, the western and southwestern Pacific Ocean. Species Species within the genus ''Minolia'' include: * '' Minolia midwayensis'' Shikama, 1977 * '' Minolia nyssonus'' (Dall, 1919) * '' Minolia peramabilis'' Carpenter, 1864 * '' Minolia pompiliodes'' Melvill, 1891 * '' Minolia pseu ...

Umbilicus (mollusc)
The umbilicus of a shell is the axially aligned, hollow cone-shaped space within the whorls of a coiled mollusc shell. The term umbilicus is often used in descriptions of gastropod shells, i.e. it is a feature present on the ventral (or under) side of many (but not all) snail shells, including some species of sea snails, land snails, and freshwater snails. The word is also applied to the depressed central area on the planispiral coiled shells of ''Nautilus'' species and fossil ammonites. (These are not gastropods, but shelled cephalopods.) In gastropods The spirally coiled whorls of gastropod shells frequently connect to each other by their inner sides, during the natural course of its formation. This results in a more or less solid central axial pillar, known as the columella. The more intimate the contact between the concave side of the whorls is, the more solid the columella becomes. On the other hand, if this connection is less intense, a hollow space inside the whorls may re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
