Polynemus Dubius
''Polynemus'' is a genus of threadfins (family Polynemidae). They are native to South and Southeast Asia and, depending on the species, occur in freshwater, brackish, and/or marine environments. The family Polynemidae is characterized by the pectoral fin that is divided into two sections; the upper one with rays that are attached whereas the lower rays are long and unattached ("threads"). In ''Polynemus'', the unattached rays number 14–15, in contrast to 3–7 in other genera. Species There are eight recognized species in this genus: * '' Polynemus aquilonaris'' Motomura, 2003 ( Northern paradise fish) * ''Polynemus bidentatus'' Motomura & Tsukawaki, 2006 * '' Polynemus dubius'' Bleeker, 1854 ( Eastern paradise fish) * ''Polynemus hornadayi'' Myers, 1936 ( Hornaday's paradise fish) * ''Polynemus kapuasensis'' Motomura & van Oijen, 2003 ( Kapuas elegant paradise fish) * ''Polynemus melanochir'' Valenciennes, 1831 (Blackhand paradise fish) ** ''Polynemus melanochir melanochi ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of '' Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
