Placocheilus is a genus of fish in the family Cyprinidae native to eastern Asia. [1]
There is currently 5 recognized species in this genus: [2]
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 3,000 species; only 1,270 of these remain extant, divided into about 200 valid genera. Cyprinids range from about 12 mm (0.5 in) in size to the 3 m (9.8 ft) giant barb. By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word kyprînos.
Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.
The Bagridae are a family of catfish that are native to Africa (Bagrus) and Asia from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes.
Rhinogobius is a genus of primarily freshwater gobies native to tropical and temperate parts of eastern Asia. Most are small, streamlined in shape, and often sexually dimorphic. Few are of commercial importance, but R. duospilus is fairly widely traded as an aquarium fish.
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.
Anabarilius is a genus of ray-finned fish in the family Cyprinidae, most of them only occurring in the area of China. Many of the species have very restricted geographic range and have been negatively impacted by introduced species, fishing, and habitat degradation; the IUCN Red List includes five Anabarilius species that are either endangered or critically endangered and one species that is considered extinct.
Garra is a genus of fish in the family Cyprinidae. These fish are one example of the "log suckers", sucker-mouthed barbs and other cyprinids commonly kept in aquaria to keep down algae. The doctor fish of Anatolia and the Middle East belongs in this genus. The majority of the more than 160 species of garras are native to Asia, but about one-fifth of the species are from Africa.
Hemimyzon is a genus of ray-finned fish in the family Balitoridae.
Oreonectes is a genus of fish in the family Nemacheilidae found in the rivers and caves of Asia. Many of these species are troglobitic.
Sinogastromyzon is a genus of hillstream loaches native to eastern Asia.
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.
Yunnanilus is a genus of small stone loaches that are endemic to southeastern China, especially Guangxi and Yunnan. They are found in rivers, streams and lakes; some species are restricted to caves.
Placocheilus caudofasciatus is a species of cyprinid native to Laos, Vietnam and China in eastern Asia. This species can reach a length of 10.9 centimetres (4.3 in) SL.
Homatula is a genus of stone loaches endemic to China.
Paracobitis is a genus of Asian stone loaches.
Gymnocypris is a genus of fish in the family Cyprinidae endemic to China.
Sikukia is a genus of cyprinid fish found in eastern Asia. There are currently four recognized species in this genus.
Myllokunmingiidae is a group of very early, jawless prehistoric fish (Agnathans) which lived during the Cambrian period. The Myllokunmingiids are the earliest known group of craniates. The group contains three genera, Haikouichthys, Myllokunmingia, and Zhongjianichthys. Their fossils have been found only in the Maotianshan Shales lagerstätte.
Saurosphargidae is an extinct family of marine reptiles known from the Early Triassic and early Middle Triassic of Europe and China.
Sinipercidae, the Chinese perches or Oriental perches, is a family of freshwater ray-finned fishes, part of the superfamiy Percoidea, suborder Percoidei of the order Perciformes.They have been placed within the temperate perch family, Percichthyidae in the past but may be more closely allied to the Centrarchidae.
