Ifremeria Nautilei
''Ifremeria nautilei'' is a species of large, deepwater hydrothermal vent sea snail, a marine gastropod mollusk in the family Provannidae, and the only species in the genus ''Ifremeria''. This species lives in the South Pacific Ocean Other species in the family Provannidae live in similar deepwater hydrothermal vent habitats. As is the case in species in the genus '' Alviniconcha'', the tissues of ''Ifremeria nautilei'' contain symbiotic bacteria which live on the sulfur from the vents, and the snails derive their nutrition from this symbiosis. This species is particularly notable because the female snails have a brood pouch on the foot, and because they release a gastropod larval form which had never been observed and described before until 2008. Description ''Ifremeria nautilei'' attains a maximum dimension of 85 mm, which is larger than other abyssochroids (length usually under 20 mm). This species hosts symbiotic chemoautotrophic bacteria that oxidize sulfur fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Provanna
''Provanna'' is a genus of sea snails, marine gastropod mollusks in the family Provannidae. The species was named after Dall's first wife. This is a very old genus with species already existing in Cretaceous seep deposits off Japan (93 - 100 million years ago). The Caribbean and the Pacific fauna were isolated about 3 million years ago by the closure of the Central American Isthmus. Description The apical whorls of the protoconch are lacking through decollation. The opening is then sealed with a calcareous plug. The sculpture of the ovate fusiform shell shows scattered sigmoidal axial ribs that are crossed by spiral cords. The whorls are broad. Habitat They are common in hydrothermal vents, hydrocarbon cold seeps and (more rarely) on deep-water food-falls, depending on the species. Most species feed on filamentous bacteria, while others feed on detritus In biology, detritus () is dead particulate organic material, as distinguished from dissolved organic material. Detritus ...

Cold Seep
A cold seep (sometimes called a cold vent) is an area of the ocean floor where hydrogen sulfide, methane and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool. ''Cold'' does not mean that the temperature of the seepage is lower than that of the surrounding sea water. On the contrary, its temperature is often slightly higher. The "cold" is relative to the very warm (at least ) conditions of a hydrothermal vent. Cold seeps constitute a biome supporting several endemic species. Cold seeps develop unique topography over time, where reactions between methane and seawater create carbonate rock formations and reefs. These reactions may also be dependent on bacterial activity. Ikaite, a hydrous calcium carbonate, can be associated with oxidizing methane at cold seeps. Types Types of cold seeps can be distinguished according to the depth, as shallow cold seeps and deep cold seeps. Cold seeps can also be distinguished in detail, as follows: * oil/gas ...

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...
