Tchangmargarya is a genus of large operculate freshwater snails, aquatic gastropod molluscs in the family Viviparidae. [2]
Tchangmargarya originally was a subgenus of Margarya , [1] and is elevated to a full genus based on molecular phylogeny and comparative morphology study. [2]
This genus appear to be endemic to Yangzong Lake and lakes in Stone Forest in Yunnan Province in the China.
There are 3 extant species of Tchangmargarya: [2]
Cyprinus is the genus of typical carps in family Cyprinidae. Most species in the genus are of East Asia origin with only the common carp in Western Asia and Europe; this invasive species has also been introduced to many other regions around the world. Cyprinus are closely related to some more barb-like genera, such as Cyclocheilichthys and Barbonymus (tinfoils). The crucian carps (Carassius) of western Eurasia, which include the goldfish, are apparently not as closely related.
Dianchi Lake, also known as Lake Dian and Kunming Lake, is a large lake located on the Yunnan-Guizhou Plateau close to Kunming, Yunnan, China. Its nickname is the "Sparkling Pearl Embedded in a Highland" and it was the model for the Kunming Lake in the Summer Palace in Beijing. Its name is the source of Yunnan's Chinese abbreviation 滇.
Viviparidae, sometimes known as the river snails or mystery snails, are a family of large aquatic gastropod mollusks, being some of the most widely distributed operculate freshwater snails.
Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae that is endemic to Guangxi, Guizhou and Yunnan in China. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.
Cipangopaludina is a genus of freshwater snails with a gill and an operculum, aquatic gastropod mollusks in the family Viviparidae.
Fuxian Lake is a body of water in Yunnan Province, China. It stretches through Chengjiang, Jiangchuan and Huaning Counties, spanning an area of 212 square kilometers. It is the third-largest lake in Yunnan, after Dian Lake and Erhai Lake, and the deepest, at 155 meters. It is the third-deepest fresh water lake in China, after Tianchi and Kanas Lake.
