Bithyniidae
Bithyniidae is a family of small freshwater snails with an operculum, aquatic gastropod molluscs in the clade Littorinimorpha.Bouchet, P.; Gofas, S. (2015). Bithyniidae Gray, 1857. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=182697 on 2016-02-28 Their minute shell is often colored. They are characterized by a calcareous operculum, a lobe on the upper surface of the neck. The ctenidium, the respiratory gill-comb, is very broad. They have a ciliary feeding habit. The kidney has a large extension towards the mantle. Genera Genera in the family Bithyniidae include: * '' Alocinna'' Annandale & Prashad, 1919 * ''Bithynia'' Leach, 1818 - type genusGlöer P. (2002).

Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

Littorinimorpha
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails ( marine species), but also including some freshwater snails ( aquatic species) and land snails (terrestrial species).Bouchet P. & Rocroi J.-P.

ConchBooks: Hackenheim, Germany. . . 397 pp. http://www.vliz.be/Vmdcdata/imis2/ref.php?refid=78278 Previously, the Linnaean taxonomy used in the taxonomy of the Gastropoda by Ponder & Lindberg (1997) ranked like this: subclass Orthogastropoda, superorder Caenogastropoda, order Sorbeoconcha, suborder Hypsogastropoda, infraorder Littorinimorpha. The order Littorinimorpha contains many gastropoda families that were formerly placed in the order Mesogastropoda, as introduced by J. Thiele in his work from 1921. Evidence for this group being monophyletic is scanty. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winston Ponder
Winston Frank Ponder (born 1941) is a noted malacologist born and educated in New Zealand who has named and described many marine and freshwater animals, especially micromolluscs. Education and career Ponder graduated with an MSc, PhD (1968) and DSc from the University of Auckland, New Zealand. He completed his Ph.D while working at the Dominion Museum but by 1969 he had taken a position at the Australian Museum, where he has remained. Ponder was the principal research scientist in the malacology section of the Australian Museum, Sydney, Australia and helped to build up the museum's mollusc collection so that it became one of the most extensive of its kind in the world. Ponder retired from this post after a long career of more than forty years of research on molluscs, and is now an Honorary Fellow of the museum. He has been the president of the Society of Australian Systematic Biologists, and was the managing editor of the journal ''Molluscan Research'' of the Malacological ...
