Guildfordia Yoka
''Guildfordia yoka'', the yoka star turban, is a species of deep-water sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails. Distribution and habitat This tropical marine species occurs in the Western Pacific off Japan and the Philippines, found at depths between . Description The size of the shell varies between . The color pattern of the shell varies from very light brownish to purple-brown. Some specimens contain only 6 whorls instead of 7 as in the holotype. The upper whorls are smooth, then follows the body whorl with scarcely 2 rows of granules, instead of 7 or 8. Towards the keel it has very irregular radiating ribs, which leave however a nearly smooth zone above the keel, with only a few spiral striae. The base of the shell is less convex than the upper part. Some specimens lack the rose-coloured line round the umbilical callosity. The aperture is oval, thick, with the nucleus in the external lower corner. The outer surface is slightly rugos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The upper surface shows a close revolving series – generally eight to ten on the body whorl – of minute laterally compressed granules. The base of the shell is slightly convex, usually with a marginal row of granules, and several rows surrounding the central callus. The Aperture (mollusc) ...

Turbinidae
Turbinidae, the turban snails, are a family of small to large marine gastropod molluscs in the superfamily Trochoidea.Bouchet, P. (2014). Turbinidae Rafinesque, 1815. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=503 on 2014-07-28 Description Turbinidae have a strong, thick calcareous operculum readily distinguishing them from the somewhat similar Trochidae or top snails, which have a corneous operculum. This strong operculum serves as a passive defensive structure against predators that try to enter by way of the aperture or that would break the shell at the outer lip. These operculum are rounded ovals that are flat with a swirl design on one side and domed on the other. They are known as Pacific cat's eye or Shiva eye shells or mermaid money, and are used for decorative purposes. Etymology The common name ''turban snail'' presumably refers to the shell's similarity in appearance to a turban. However, the scient ...
