Travancoria is a small genus of hillstream loaches endemic to India.
There are currently two recognized species in this genus: [1]
Cypriniformes is an order of ray-finned fish, including the carps, minnows, loaches, and relatives. Cypriniformes is an Order within the Superorder Ostariophysi consisting of "Carp-like" Ostariophysins. This order contains 11-12 families, although some authorities have designated as many as 23, over 400 genera, and more than 4,250 species, with new species being described every few months or so, and new genera being recognized frequently. They are most diverse in southeastern Asia, and are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.
Cobitidae, also known as the True loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families. The family includes about 260 described species. New species are being described regularly.
The hillstream loaches or river loaches are a family, the Balitoridae, of small fish from South, Southeast and East Asia. The family includes about 202 species. They are sometimes sold as "lizardfish" or "flossensaugers". Many of the species are popular for aquaria, species in the genus Sewellia are most commonly sold in the aquaria trade. They have a number of similarities with the Cobitidae, their sibling family of "loaches", such as multiple barbels around the mouth. They should not be confused with the loricariids, which look similar but are a family of catfish.
Pangio is a genus of small Asian freshwater fish in the true loach family Cobitidae. In earlier taxonomic schemes it was known as Acanthophthalmus. The "kuhli loach" is well-known in the aquarium trade and commonly identified as P. kuhlii, but most individuals actually appear to be P. semicincta.
Botia is a genus of freshwater fish in the loach family (Botiidae). It was a large genus with about 20 species. In 2004 Maurice Kottelat proposed in his paper to divide the genus into four related genera based on fish appearance and locality:
Yasuhikotakia is a genus of botiid loaches, many which are popular aquarium fish. It is named in honor of Japanese collector/researcher Dr. Yasuhiko Taki. This genus has been separated from the genus Botia in the paper by Maurice Kottelat in 2004.
Hemimyzon is a genus of ray-finned fish in the family Balitoridae.
Nemacheilus is a genus of stone loaches native to Asia.
Schistura is a genus of fish in the stone loach family Nemacheilidae native to the streams and rivers of the southern and eastern Asia. Some of these species are troglobitic.
Maurice Kottelat is a Swiss ichthyologist specializing in Eurasian freshwater fishes.
Loaches are fish of the superfamily Cobitoidea. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidea comprise about 107 genera divided among 9 families.
Ellopostoma is a small genus of loaches native to Southeast Asia. This is the only genus in the family Ellopostomatidae, having been confirmed as being in a family of its own by M. Kottelat in his review of the loaches in 2012.
Vaillantella, the long-fin loaches, is a small genus of loaches found in Southeast Asia. This genus is the only member of the family Vaillantellidae having been confirmed as such by M. Kottelat in his review of the loaches in 2012.
Vanmanenia is a genus of loaches from China and mainland Southeast Asia.
Serpenticobitis, popularly known as serpent loaches, is a small genus of loaches found in the Mekong River Basin in Southeast Asia. It is the only genus in the family Serpenticobitidae.
The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream environments, mostly in Eurasia, with one genus, Afronemacheilus found in Africa. The family includes about 790 species.
Ambastaia is a genus of botiid loaches native to Mainland Southeast Asia and China. The species in this genus were formerly included in Yasuhikotakia.
Balitoropsis also known as the lizard loaches is a genus of hillstream loaches native to eastern Asia.
The Gastromyzontidae are a family of loaches native to China and Southeast Asia, where typically found in streams and rivers with a fast current. The family includes about 137 species in eighteen genera. This family was resurrected by M. Kottelat in his review and revision of the loaches in 2012. They are commonly called hillstream loaches.
Travancoria elongata, which is also known as Periyar loach, is an endangered species of freshwater fish only found in Chalakudy River and Periyar River, from the family of Balitoridae (River loaches). These fishes grows up to 11 centimetres (4.3 in) long. Large-scale capture of these species from rivers in order to export them to the international market as ornamental fish has become a threat to this species. Included in the Red Data Book, they are on the verge of extinction.
