Cottocomephorus
''Cottocomephorus'' is a genus of freshwater ray-finned fishes belonging to the Family (biology), family Cottidae, the typical sculpins. This genus is endemism, endemic to Lake Baikal and its surrounding tributaries in Russia. They have relatively large pectoral fins and reach up to in total length. They are an important food for the Baikal seal, during the winter second only to the golomyankas. Taxonomy ''Cottocomephorus'' was first proposed as a monospecific genus in 1900 by the French ichthyologist Jacques Pellegrin when he Species description, described ''Cottocomephorus megalops'' as a new species. The genus was classified in the family Cottocomephoridae; however, the 5th edition of ''Fishes of the World'' classifies the genus within the subfamily Cottinae of the family Cottidae, studies having found that the genera formerly included in the Cottocomephoridae were a clade arising from the genus ''Cottus (fish), Cottus''.

Cottocomephorus Grewingkii
The Baikal yellowfin (''Cottocomephorus grewingkii''), also known as the yellow-finned sculpin or yellow-wing sculpin, is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is endemic to Lake Baikal and its tributaries in Siberia, Russia. It is most common in the southern part of the lake and lives from near the shore to a depth of . Appearance It can reach up to in total length, but most are . They have relatively large pectoral fins, which are yellow in males. During the breeding season, the male's head becomes black when encountering other males. Behavior The Baikal yellowfin feeds on copepods (notably ''Epischura baikalensis''), amphipods, insect larvae and fish larvae. There are three separate breeding periods: March, May and August. There are some differences in the breeding behavior and site depending on when the fish breeds. Breeding occurs at a depth of in a crevice under a rock, which measures from to . The dis ...

Baikal Seal
The Baikal seal, Lake Baikal seal or (''Pusa sibirica''), is a species of earless seal endemic to Lake Baikal in Siberia, Russia. Like the Caspian seal, it is related to the Arctic ringed seal. The Baikal seal is one of the smallest true seals and the only exclusively freshwater pinniped species.Randall R. Reeves, Brent S. Stewart, Phillip J. clapham, James A. Powell, ''"National Audubon Society Guide to the Marine Mammals of the World"'', Alfred A. Knopf publishing, New York, 2002 A subpopulation of inland harbour seals living in the Hudson Bay region of Quebec, Canada (Lacs des Loups Marins harbour seals), as well as the Saimaa ringed seal and the Ladoga seal (both ringed seal subspecies), are also found in fresh water, but these seals are part of species that also have marine populations. The most recent population estimates are 80,000 to 100,000 animals, roughly equaling the expected carrying capacity of the lake. At present, the species is not considered threatened. Descrip ...

Jacques Pellegrin
Jacques Pellegrin (12 June 1873, Paris – 12 August 1944) was a French zoologist. In Paris, he worked under zoologist Léon Vaillant (chair of reptiles and fishes) at the ''Muséum national d'histoire naturelle''. From 1897, Pellegrin served as ''préparateur'' at the museum. He obtained doctorates in medicine (1899) and science (1904), and in 1908 was named as an assistant director. After many missions abroad, he became sub-director of the museum in 1937, and replaced Louis Roule (1861–1942) as the chairperson of herpetology and ichthyology. He published over 600 scientific books and articles and discovered around 350 new species. He named a number of fishes from the family Cichlidae, such as the genera '' Astatoreochromis'', '' Astatotilapia'', '' Boulengerochromis'', ''Lepidiolamprologus'', ''Nanochromis'' and '' Ophthalmotilapia''. Taxa named in his honor He has the following species named in his honor: * The Clingfish '' Apletodon pellegrini'' * ''Enteromius pelle ...

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] |
Taxa Named By Jacques Pellegrin
In biology, a taxon ( back-formation from '' taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vasilii Evgrafovich Yakovlev
Vasily Evgrafovich Yakovlev (russian: Василий Евграфович Яковлев; also transliterated Vasiliy Ewgrafowitsch Jakovlev or Vasiliy Yevgrafovich Yakovlev; 9 February 1839 – 15 August 1908) was a Russian zoologist who studied fishes, molluscs and insects. He is not to be confused with Alexander Ivanovich Yakovlev, another entomologist. His name was spelled Wassily Ewgrafowitsch Jakowlew in French, in which he sometimes wrote. Yakovlev lived in Saint Petersburg, but travelled extensively collecting insects in the Crimea, Volga region and Turkestan until he finally travelled and settled in Griffin, GA. Although primarily interested in Coleoptera Yakovlev also worked on Hemiptera and Lepidoptera. From around 1867 Yakovlev conducted zoological observations in the vicinity of Astrakhan. Yakovlev described Caspian roach The Caspian roach (''Rutilus caspicus'') is a species of roach fish living in the Caspian Sea. The Caspian roach can be distinguished fr ...

Benedykt Dybowski
Benedykt Tadeusz Dybowski (12 May 183331 January 1930) was a Polish naturalist and physician. Life Benedykt Dybowski was born in Adamaryni, within the Minsk Governorate of the Russian Empire to Polish nobility. He was the brother of naturalist Władysław Dybowski and the cousin of the French explorer Jean Dybowski. He studied at Minsk High School, and later medicine at Tartu (earlier Dorpat) University in present-day Estonia. He later studied at Wroclaw University and went on expeditions to seek and study oceanic fishes and crustaceans. He became a professor of zoology at the Warsaw main school. In 1864 he was arrested and condemned to death for taking part in the Polish January Uprising. His sentence was later reduced to 12 years in Siberia. He started studying the natural history of Siberia and in 1866 a governor Muraviov dismissed Dybowski from hard labour (''katorga''), renewed his civil rights and proposed him to work as a doctor in hospital. He later settled in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
