Amblycipitidae
The Amblycipitidae are a family of catfishes, commonly known as torrent catfishes. It includes three genus, genera, ''Amblyceps'', ''Liobagrus'', and ''Xiurenbagrus'', and about 36 species. Taxonomy The family Amblycipitidae is a monophyly, monophyletic group containing four monophyletic genera, ''Amblyceps'', ''Liobagrus'', ''Nahangbagrus'' and ''Xiurenbagrus''. It is the most basal (phylogenetics), basal Sisoroidea, sisoroid family and is cladistics, sister to a clade formed by the remaining families. The genera ''Amblyceps'' and ''Liobagrus'' are a sister group pair that is, in turn, sister to ''Xiurenbagrus''. Distribution and habitat These kinds of fishes can be found in swift freshwater streams in southern and eastern Asia, including Pakistan across northern India to Malaysia, China, Korea, and Japan. ''Amblyceps'' are mainly distributed in India and the Malay Peninsula. ''Liobagrus'' fishes are distributed in the Yangtze River basin, Taiwan, Japan, and the Korea Peninsula. ...

Amblyceps Carinatum
''Amblyceps carinatum'' is a species of catfish belonging to the family Amblycipitidae. It is only known from the upper part of the Irrawaddy River basin in Myanmar. This is a small catfish (up to 36 mm standard length) found in fast flowing streams. The main characteristic which distinguishes it from its congeners is the shape of the adipose fin: in ''A. carinatum'' it takes the form of a long low ridge starting just behind the dorsal fin whilst in all other ''Amblyceps ''Amblyceps'' is a genus of fish in the family Amblycipitidae.Ferraris, C.J.Jr. (2007)Checklist of catfishes, recent and fossil (Osteichthyes: Siluriformes), and catalogue of siluriform primary types.''Zootaxa, 1418: 1–628.''

Xiurenbagrus
''Xiurenbagrus'' is a genus of torrent catfishes (order Siluriformes) of the family Amblycipitidae. It includes three species. Taxonomy ''X. xiurenensis'' was first described in 1981 as ''Liobagrus xiurenensis''. However, it was realized that ''Liobagrus'' would not be monophyletic with the inclusion of this species, so ''Xiurenbagrus'' was erected. The genera ''Amblyceps'' and ''Liobagrus'' are sister group pair that is, in turn, sister to ''Xiurenbagrus''.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...
