Triplophysa dongganensis is a species of stone loach in the family Nemacheilidae. It is endemic to Guangxi, China. [1]
This species reaches a standard length of 10.6 cm (4.2 in). [2]
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.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. They can be distinguished from other genera of Nemacheilidae by marked sexual dimorphism, including the development of nuptial tubercles on breeding males. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species all but Hedinichthys have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
Triplophysa xiangxiensis is a species of stone loach endemic to Yuan River in Hunan, China. It is a cave-dwelling species. It grows to 9.9 cm (3.9 in) SL.
Triplophysa alexandrae is a species of stone loach in the genus Triplophysa endemic to Sichuan, China.
Triplophysa bleekeri is a species of stone loach in the genus Triplophysa. It is endemic to China. It grows to 8.2 cm (3.2 in) TL. Having a wide distribution across the Qinghai-Tibet Plateau, it lives in fast-flowing rivers from 200 to 3,000m in altitude. Being an unusual species inhabiting high-altitude regions, it is an excellent model to investigate the genetic mechanisms of adaptation to the local environment. With this in mind a chromosomal-scale genome assembly was sequenced and assembled with a genome size of ~628 Mb. This data finding that the Triplophysa genus likely diverged when the Qinghai-Tibet Plateau elevated by >4,000 m roughly 40 million years ago.
Triplophysa dalaica is a species of stone loach. It is only known from Hulun Lake in Inner Mongolia, China; it is believed to occur more widely as fish in this genus typically occur in running water.
Triplophysa dorsalis, the grey stone loach, is a species of stone loach in the genus Triplophysa that lives in freshwater. It is found in Uzbekistan, Kazakhstan, Kyrgyzstan and Xinjiang.
Triplophysa flavicorpus is a species of stone loach in the genus Triplophysa endemic to the Hongshui River in Guangxi, China. It grows to 10.4 cm (4.1 in) SL.
Triplophysa gracilis is a species of stone loach in the genus Triplophysa. It is found in Pakistan, India, and China. It grows to 11 cm (4.3 in) SL and lives in standing waters and deeper parts of rivers.
Triplophysa intermedia is a species of stone loach in the genus Triplophysa. The species has only been found in Hulun Lake in Inner Mongolia, China; but is believed to appear in other locations as well since fish in this genus are typically found in running water.
Triplophysa longipectoralis is a cave-living species of stone loach with vestigial eyes. The fish lives in clear water at temperatures below 20 °C. The holotype was caught in Xunle town, Huanjiang Maonan Autonomous County in the Liu River basin, Guangxi, China and was described by Zheng et al. in 2009.
Triplophysa brachyptera is a species of stone loach in the genus Triplophysa. It is endemic to the Gansu Province, China. It grows to 13.7 cm (5.4 in) SL.
Triplophysa obtusirostra is a species of ray-finned fish in the genus Triplophysa. It is endemic to Qinghai province, China, near the origin of the Yellow River.
Triplophysa siluroides is a large species of stone loach, which is endemic to the upper parts of the Yellow River basin in the Chinese provinces of Qinghai, Gansu and Sichuan.
Triplophysa stenura is a species of ray-finned fish in the genus Triplophysa. It lives in swift-flowing streams and is known from the Upper Yangtze, Upper Mekong, Upper Salween and Upper Brahmaputra river drainages in China and Vietnam. Whether this apparently widespread species really is one species needs to be studied. It grows to 13.8 cm (5.4 in) SL.
The Tibetan stone loach is a species of ray-finned fish in the family Nemacheilidae. The specific name is sometimes spelled stoliczkae but the original spelling used by Steindachner is stoličkai. It is found in southern and central Asia.
Triplophysa yunnanensis is a species of ray-finned fish in the genus Triplophysa. It is a cave-dwelling species endemic to Yunnan, China. It grows to 6.3 cm (2.5 in) SL.
Triplophysa zhaoi is a species of ray-finned fish in the genus Triplophysa. It grows to 8 cm (3.1 in) SL. It is endemic to China and inhabits swampy creeks.
Triplophysa zhenfengensis is a species of stone loach in the genus Triplophysa. It is endemic to China and first discovered in Guangxi.
Triplophysa anshuiensis is a species of stone loach in the family Nemacheilidae. It is endemic to Lingyun County in Guangxi, China, where it lives in a karst cave.
