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 Mangois
''Amblyceps'' is a genus of fish in the family (biology), 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.'' The genera ''Amblyceps'' and ''Liobagrus'' are cladistics, sister group pair that is, in turn, sister to ''Xiurenbagrus''. These species are easily distinguished by the presence of pinnate processes along with the median caudal fin, caudal-fin rays (although these processes may be poorly developed in some species), a prominent cup-like skin flap above the base of the pectoral fin, pectoral spine, and the adipose fin largely separate from the caudal fin. In most species the caudal fin is deeply forked; ''A. apangi'' and ''A. murraystuarti'' differ in having their caudal fin truncate. ''Amblyceps'' species may reach about 100 millimetres (3.94 in) fish measurement, SL.Chen, X. & Lundberg, J.G. (1995): ''Xiurenbagrus'', a New Genus o ...

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 ...

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''.

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sisoroidea
Sisoroidea is a superfamily of catfishes ( order Siluriformes). It contains the four families Amblycipitidae, Akysidae, Sisoridae, and Erethistidae; many sources also include Aspredinidae. With Aspredinidae, this superfamily includes about 42 genera and 230 species. Taxonomy Sisoroidea is sister to the Loricarioidea. The monophyly of this superfamily is supported by a number of morphological characters. Amblycipitidae is the most basal family and is sister to the remaining families. Based on morphological data, Erethistidae is the sister group to Aspredinidae, with Sisoridae being the sister group of the clade formed by these two families. However, it has been proposed to move the erethistid genera back into Sisoridae. Also, some authors have removed Aspredinidae from Sisoroidea, having found it to be more closely related to Doradoidea (Doradidae, Auchenipteridae, and possibly Mochokidae) with morphological and molecular evidence. Distribution Sisoroidea includes almost ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fishes Of The World
''Fishes of the World'' by the American ichthyologist Joseph S. Nelson (1937–2011) is a standard reference for fish systematics. Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science. The book begins with a general overview of ichthyology, although it is not self-contained. After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion. Each family (biology), family gets at least one paragraph, and usually a body outline drawing; large families have subfamilies and tribes described as well. Notable genera and species are mentioned, while the book generally does not deal with the species-level diversity. The complexities of the higher taxa are described succinctly, with many references for difficult points. The book does not involve color illustrations. The fourth edition was the first to incorporate the wide use of DNA analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malay Peninsula
The Malay Peninsula (Malay: ''Semenanjung Tanah Melayu'') is a peninsula in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung). The island country of Singapore also has historical and cultural ties with the region. The indigenous people of the peninsula are the Malays, an Austronesian people. The Titiwangsa Mountains are part of the Tenasserim Hills system and form the backbone of the peninsula and the southernmost section of the central cordillera, which runs from Tibet through the Kra Isthmus, the peninsula's narrowest point, into the Malay Peninsula. The Strait of Malacca separates the Malay Peninsula from the Indonesian island of Sumatra, and the south coast is separated from the island of Singapore by the Straits of Johor.
