Margarya
''Margarya'' is a genus of large operculate freshwater snails, aquatic gastropod mollusks in the family Viviparidae.Bouchet, P. (2014). Margarya G. Nevill, 1877. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=758767 on 2014-12-10 Taxonomy The genus ''Margarya'' was described by Nevill (1877) based on shells of the type species collected by A.R. Margary from Lake Erhai, the type locality of ''Margarya melanioides''. Based on shell and radular morphology, Tchang & Tsi (1949) revised this genus for the first time and recognized seven distinct species. He created two subgenera of ''Margarya'' , viz ''Tchangmargarya'' and ''Mabillemargarya''. The first molecular phylogeny showed that the genus ''Margarya'' is polyphyletic and divided into three distinct clades. Combining study of comparative morphology and molecular phylogeny, Zhang ''et al''. revised the systematics of ''Margarya'' and recognized eight genuine extant sp ...

Viviparidae
Viviparidae, sometimes known as the river snails or mystery snails, are a family of large operculate freshwater snails, aquatic gastropod mollusks. This family is classified in the informal group Architaenioglossa according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005. Distribution This family occurs nearly worldwide in temperate and tropical regions, with the exception that they are absent from South America. There are two genera of Viviparidae in Africa: ''Bellamya'' and ''Neothauma''. The oldest known vivparid is ''Viviparus langtonensis'' from the Middle Jurassic of England. The oldest records from the Southern Hemisphere is from the Late Jurassic Talbragar fossil beds of Australia. Taxonomy The family Viviparidae contains 3 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005): * Viviparinae Gray, 1847 (1833) - synonyms: Paludinidae Fitzinger, 1833 (inv.); Kosoviinae Atanackovic, 1859 (n.a.) * Bellamyinae Rohrbach, 193 ...

Aquatic Animal
An aquatic animal is any animal, whether invertebrate or vertebrate, that lives in water for most or all of its lifetime. Many insects such as mosquitoes, mayflies, dragonflies and caddisflies have aquatic larvae, with winged adults. Aquatic animals may breathe air or extract oxygen from water through specialised organs called gills, or directly through the skin. Natural environments and the animals that live in them can be categorized as aquatic (water) or terrestrial (land). This designation is polyphyletic. Description The term aquatic can be applied to animals that live in either fresh water or salt water. However, the adjective marine is most commonly used for animals that live in saltwater, i.e. in oceans, seas, etc. Aquatic animals (especially freshwater animals) are often of special concern to conservationists because of the fragility of their environments. Aquatic animals are subject to pressure from overfishing, destructive fishing, marine pollution, hunting, and cli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Fuxian Lake
Fuxian Lake () stretches out through Chengjiang, Jiangchuan and Huaning Counties in Yunnan Province, spanning an area of 212 square kilometers. The lake is ranked third-largest in Yunnan, after Dian Lake and Erhai Lake. Also the deepest lake in Yunnan, it is 155 meters deep at its greatest depth. It is also the third-deepest fresh water lake in China, after Tianchi and Kanas Lake. Climate Fuxian Lake has humid subtropical climate (Köppen climate classification ''Cwa'') with humid summers and mild dry winters.
