Semisulcospiridae
Semisulcospiridae, common name semisulcospirids, is a family of freshwater snails, aquatic gilled gastropod mollusks with an operculum, in the superfamily Cerithioidea. MolluscaBase eds. (2021). MolluscaBase. Semisulcospiridae J. P. E. Morrison, 1952. Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=715954 on 2021-03-08 Semisulcospiridae diversified from the Pleuroceridae about 90 million years ago, in the Cretaceous. Distribution The family Semisulcospiridae occurs in western North America, the Far East of Russia, Korea, Japan, China and Vietnam. Taxonomy The family Semisulcospiridae was introduced as just a name (nomen nudum) by Morrison (1952), without a diagnosis of the taxon. It is a valid taxon however, because its name has been used as valid. 2005 taxonomy According to the taxonomy of Bouchet & Rocroi (2005), Semisulcospiridae was a subfamily within the family Pleuroceridae. 2009 taxonomy The su ...

Juga
''Juga'' is a genus of freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Semisulcospiridae. These snails are native to the rivers of the northwestern United States and adjacent British Columbia. Several species are endemic to isolated large springs in the American Great Basin.Strong, E. E., & Whelan, N. V. (2019). Assessing the diversity of western North American Juga (Semisulcospiridae, Gastropoda). Molecular Phylogenetics and Evolution, 136, 87-103. The most abundant and widespread species, ''Juga plicifera'', attains a height of up to 35 mm. It is sculpted with fine spiral ridges and variably developed ribs that frequently disappear in parts of the shell made as the animal matures. Species The following species and subspecies are recognized: Subgenus ''Juga'' s.s. * ''Juga hemphilli'' (J. Henderson, 1935) ** ''Juga hemphilli dallesensis'' (J.

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 Ce ...

Cerithioidea
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea are included unassigned in the subclass Caenogastropoda. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time. Ecology Cerithioidea is a very diverse superfamily. Its species can be found worldwide mainly in tropic and subtropic seas on rocky intertidal shores, seagrass beds and algal fronds, but also in estuarine and freshwater habitats. The freshwater species are found on all continents, except Antarctica. They are dominant members of mangrove forests, estuarine mudflats, fast-flowing rivers and placid lakes.Healy J. M. & Wells F. E. (). ''Mollusca, The Southern Syntthesis. Fauna of Australia.''

Pleuroceridae Pleuroceridae, common name pleurocerids, is a family of small to medium-sized freshwater snails, aquatic gilled gastropod mollusks in the superfamily Cerithioidea.These snails have an operculum and typically a robust high-spired shell. Reproduction is iteroparous, and juvenile snails emerge from eggs laid on a firm surface by a gonochoristic female. There is no veliger stage. Distribution As currently defined, this family is confined entirely to eastern North American fresh waters. Similar snails formerly classified with Pleuroceridae, but now assigned to other families are widespread in temperate and tropical parts of Southern and Eastern Asia, and Africa. Most require unpolluted rivers and streams, but a few are adapted to living in lakes or reservoirs. Taxonomy 2005 taxonomy The following two subfamilies have been recognized in the taxonomy of Bouchet & Rocroi (2005): * Pleurocerinae P. Fischer, 1885 - synonyms: Ceriphasiinae Gill, 1863; Strepomatidae Haldeman, 1864; ... [...More Info...] [...Related Items...] |
