Loach
Loaches are ray-finned fishes of the suborder Cobitoidei. They are freshwater, benthic (bottom-dwelling) fish found in rivers and creeks throughout Eurasia and North Africa, northern Africa. Loaches are among the most diverse groups of fish; the 1249 known species of Cobitoidei comprise about 107 genus, genera divided among 9 family (biology), families. Etymology The name Cobitoidei comes from the type genus, ''Cobitis'', described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, 10th edition of ''Systema Naturae''. However, its origin predates modern zoological nomenclature and derives from a term used by Aristotle to refer to "small fishes that bury... like the Gudgeon (fish), gudgeon." Description Loaches display a wide variety of morphologies, making the group difficult to characterize as a whole using external traits. They range in adult length from the 23 mm (1 in) miniature eel-loach, ''Pangio longimanus'', to the 50 cm (20 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypriniformes
Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid ( carps and their kin) fish, such as barbs, loaches, botias, and minnows (among others). Cypriniformes is an "order-within-an-order", placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11–12 families (with some authorities having listed as many as 23), over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently.Eschmeyer, W.N., Fong, J.D. (2015Species by family/subfamilyin the Catalog of Fishes, California Academy of Sciences (retrieved 2 July 2015) Cyprinids are most diverse in South and Southeast Asia and are entirely absent from Australia and South America.Nelson (2006) At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.

Cobitidae
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 (see below). The family includes about 260 described species. New species are being described regularly.Perdices, A., Bohlen, J., Šlechtová, V. & Doadrio, I. (2016): Molecular Evidence for Multiple Origins of the European Spined Loaches (Teleostei, Cobitidae). ''PLoS ONE, 11 (1): e0144628.'' Description and ecology The body forms of the Cobitidae tend to be vermiform – worm-shaped, long and thin. Most true loaches do not have true scales, and like many other Cypriniformes or catfishes, they have barbels at their mouths (usually three to six pairs). Some other traits typically found in this family are a small bottom-facing mouth suited to their scavenging benthic lifestyle, an erectile spine below the eye, and a single row of pharyngeal (throat) teeth.

Botiidae
Botiidae, the pointface loaches, is a family of cypriniform ray-finned fishes from South, Southeast, and East Asia. Until recently they were placed in the true loach family Cobitidae, until Maurice Kottelat revised the loaches and re-elevated this taxon to family rank in 2012.Kottelat, M. (2012)Conspectus cobitidum: an inventory of the loaches of the world (Teleostei: Cypriniformes: Cobitoidei). ''The Raffles Bulletin of Zoology'', Supplement No. 26: 1-199. The family includes about 56 species. The Botiids are more robust than most of their relatives in Cobitidae and tend to have a more or less arched back, yielding an altogether more fusiform shape. Botiids typically have a pointed snout of intermediate length, while many cobitids are remarkably stub-nosed. Botiids are generally fairly small, with maximum lengths between depending on the species involved, although '' Leptobotia elongata'' reaches ('' Chromobotia macracanthus'' has been claimed to reach a similar size, but t ...

Spined Loach
The spined loach (''Cobitis taenia'') is a common freshwater fish in Europe. It is sometimes known as spotted weather loach, not to be confused with the "typical" weather loaches of the genus '' Misgurnus''. This is the type species of the spiny loach genus ('' Cobitis'') and the true loach family ( Cobitidae). Description The spined loach typically reaches an adult length of , although females may grow up to . Adults weigh between . Their backs feature a yellow-brown colouring interspersed with many small grey or brown scales on the spinal ridge. The scales on the belly are pale yellow or orange. The body overall is long and thin. There are 6 barbels around the mouth. Under the eyes there is a two-pointed spike, with which the fish can inflict a painful sting. Distribution and relationships It is found from the Volga River basin to France. Generally it occurs across much of temperate Europe north of the Alpide belt, with the exceptions of Ireland, Scotland, Wales and nor ...

Acantopsis
''Acantopsis'' is a genus of freshwater fishes, commonly known as horseface loaches or banana-root fishes, in the family Cobitidae. Fishes of the genus ''Acantopsis'' inhabit sandy riverbeds throughout Southeast Asia and are most diverse in the Mekong River in Thailand, Laos, and Cambodia wherein five species are known to occur. The common horseface loach, '' A. rungthipae'', is popular in the aquarium trade. Species The species in the genus are:Fricke, R., Eschmeyer, W. N. & R. van der Laan (eds) 2018.

Pangio Longimanus
''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''. The type species is ''Cobitis cinnamomea'' McClelland 1839, now known as '' Pangio pangia''. These fish are best represented in Southeast Asia where all but five of the species live, including the Greater Sunda Islands with sixteen species. The five species found outside Southeast Asia are from India and Myanmar. They inhabit a wide range of mostly calm waters such as streams, swamps (often peat swamps) and backwaters, but there are also species in fast-flowing waters, and one, ''P. bhujia'', lives underground. Species There are currently 35 recognized species in this genus: * '' Pangio agma'' ( M. E. Burridge, 1992) * '' Pangio alcoides'' Kottelat & K. K. P. L ...

Hillstream Loach
Balitoridae, the hillstream loaches or river loaches, is a family, of small fish from South, Southeast and East Asia. The family includes about 202 species. They are sometimes sold as "lizardfish" or (in Germany) "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. Most species are rheophilic, living in swift, clear and well-oxygenated streams. Several species of the family live in fast-flowing streams or torrents and have modified ventral fins used for clinging to rocks. The subfamily Nemacheilinae has recently been separated as a distinct family, Nemacheilidae The Nemacheilidae, or stone loaches, are a family of cypriniform fishes that inhabit stream envir ...

Fish Scale
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term ''scale'' derives from the Old French , meaning a shell pod or husk. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology (biology), morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. Most bony fishes are covered with the cycloid scales of salmon and carp, or the ctenoid scales of perch, or the ganoid scales of sturgeons and gars. Cartilaginous fishes (sharks and rays) are covered with placoi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
