Trichomycterus Itacarambiensis
''Trichomycterus'' is a genus of fish in the family Trichomycteridae, the largest genus of its family with over 170 species currently described. This genus is native to freshwater habitats in Central and South America. These fish are generally small, usually about in standard length, although the largest, '' T. rivulatus'', can reach more than twice this size. Species differ from one another primarily in body proportions, fin ray counts and colouration.Fernández, L. & Osinaga, K. (2006)A New ''Trichomycterus'' (Siluriformes: Trichomycteridae) from Aguarague National Park of the Bolivian Preandean Region, with Comments on Relationships within of the Genus.''Environmental Biology of Fishes, 75 (4): 385–393.'' Despite their relatively small size, some, such as '' T. punctulatus'', support fisheries and are important in the local cuisine. Taxonomy This genus is defined by the lack of specializations found in other trichomycterids and is certainly polyphyletic.Alencar, A.R. & Cost ...

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoology, 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
