Hemibagrus
''Hemibagrus'' is a genus of catfishes (order Siluriformes) of the family Bagridae. The genus ''Hemibagrus'' is known from Southeast Asia, India, and southern China. Members of this genus are found ubiquitously in river drainages east of the Ganges-Brahmaputra basin and south of the Yangtze basin, and reach their greatest diversity in Sundaland. This genus consists of large-sized catfishes. '' H. wyckioides'' is the largest Bagrid catfish in central Indochina and may reach 80 kilograms. It includes species with depressed (flattened) heads, rugose (ridged or wrinkled) head shields not covered by skin, and moderately long adipose fins. In Southeast Asia, ''Hemibagrus'' species are an important source of animal protein. The extinct species, '' H. major'', is a fossil species from a Miocene lake fauna from what is now Ban Nong Pia, Phetchabun Province of Thailand. Species There are currently 41 recognized species in this genus: * '' Hemibagrus amemiyai'' ( Sh. Kimura, 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canna Maria Louise Popta
Canna Maria Louise Popta (31 May 1860 – 13 June 1929)L.B. Holthuis, Biography i1820-1958, Rijksmuseum van Natuurlijke Historie page 82 (in Dutch). was a Dutch biologist. Born in Breda, Popta was one of the first women to enrol as a student at Leiden University where she studied for a degree in geology, zoology and botany, allowing her to teach in high schools. She studied for her doctorate at the University of Berne under the supervision of Eduard Fischer, her thesis was on the Hemiasci, a fungal group which was then thought to be the link between the Phycomycetes and Ascomycota. After completing her doctorate she obtained a position at the Rijksmuseum van Natuurlijke Historie in Leiden as a Lab Assistant to the curator of reptiles, amphibians and fishes. During her career at the museum she concentrated mainly on ichthyology, eventually retiring in 1928, and dying the following year in Leiden. She wrote over 40 scientific papers and a number of articles for encyclopedias. For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Tate Regan
Charles Tate Regan FRS (1 February 1878 – 12 January 1943) was a British ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Species Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: *A Thorny Catfish ''Anadoras regani'' (Steindachner, 1908) *The Dwarf Cichlid '' Apistogramma regani'' *'' Apogon regani'' *A Catfish ''Astroblepus regani'' * ...
