Liobagrus
''Liobagrus'' is a genus of catfishes of the family Amblycipitidae. ''Liobagrus'' fishes are distributed in the Yangtze River basin, Taiwan, Japan, and the Korea Peninsula. The adipose fin of these fishes is a confluent with the caudal fin. The nostrils are far apart, unlike those found in ''Amblyceps''. Most ''Liobagrus'' species grow to about 100 millimetres (3.94 in) SL. Taxonomy No shared derived characteristic has been found to diagnose the genus ''Liobagrus''. However, it is maintained that this genus is currently monophyletic. ''Liobagrus'' has been placed in the family Bagridae. Later, it was found to more closely resemble ''Amblyceps'', and was transferred to Amblycipitidae. '' Xiurenbagrus'' was erected because ''Liobagrus'' would not be monophyletic with ''Liobagrus xiurenensis'', now ''Xiurenbagrus xiurenensis''. The genera ''Amblyceps'' and ''Liobagrus'' are sister group pair that is, in turn, sister to ''Xiurenbagrus''. Species There are currently 15 re ...

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. ...

Liobagrus Chenghaiensis
''Liobagrus chenghaiensis'' is a species of catfish in the family Amblycipitidae (the torrent catfishes) endemic to China, where it is only known from lake Chenghai in the province of Yunnan. ''L. chenghaiensis'' is distinguished from all other species of ''Liobagrus'' with a serrated posterior margin of the pectoral-fin spine by possessing a free apex on the posterior margin of the adipose fin. It is similar to '' L. marginatus'' in the presence of a subtruncate caudal fin Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as se ..., by which both are distinguished from all other Chinese congeners with a serrated posterior margin of the pectoral-fin spine.

Liobagrus Aequilabris
''Liobagrus aequilabris'' is a species of catfish in the family Amblycipitidae (the torrent catfishes). This species is endemic to China, where it is only known from the Xiang River, a tributary of the Yangtze River, in Guangxi province, but may also be present in the Li River, a tributary of the Pearl River, due to the presence of the Lingqu Canal connecting the Xiang and Li Rivers. ''L. aequilabris'' reaches a length of SL. It differs from other members of its genus in lacking large, retrorse serrations on the posterior edge of the pectoral-fin spine, having upper and lower jaws of equal length, relatively long dorsal (7.5-10.2 % of SL) and pectoral-fin (9.1-12.1 % of SL) spines, a relatively long caudal fin (20.1-26.9 % of SL), and relatively few post-Weberian Maximilian Karl Emil Weber (; ; 21 April 186414 June 1920) was a German sociologist, historian, jurist and political economist, who is regarded as among the most important theorists of the development of mode ...

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''.

Bagridae
The Bagridae are a family of catfish that are native to Africa ('' Bagrus'') and Asia (all other genera) from Japan to Borneo. It includes about 245 species. These fish are commonly known as naked catfishes or bagrid catfishes. Many large bagrids are important as a source of food. Some species are also kept as aquarium fishes. Physical characteristics The dorsal fin is preceded by a spine. The adipose fin is present and can have a relatively long base in some species. The pectoral fin spine can be serrated. The body is completely naked (they have no scales). The maximum length is about . Fishes of the family Bagridae have four pairs of well-developed barbels covered by a layer of taste bud-enriched epithelium. Taxonomy The taxonomy of this family has changed rapidly. Nelson (2006) comments how "the family is very different from that recognized in Nelson (1994)". Claroteidae and Austroglanididae contain species that were previously bagrids. Auchenoglanididae is considered by some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sun Zhi-Wei (ichthyologist)
The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared radiation, and is the most important source of energy for life on Earth. The Sun's radius is about , or 109 times that of Earth. Its mass is about 330,000 times that of Earth, comprising about 99.86% of the total mass of the Solar System. Roughly three-quarters of the Sun's mass consists of hydrogen (~73%); the rest is mostly helium (~25%), with much smaller quantities of heavier elements, including oxygen, carbon, neon, and iron. The Sun is a G-type main-sequence star (G2V). As such, it is informally, and not completely accurately, referred to as a yellow dwarf (its light is actually white). It formed approximately 4.6 billionAll numbers in this article are short scale. One billion is 109, or 1,000,000,000. years ago from the gravita ...
