Alexei Alexeyevich Korotnev
Alexey ( ; ), is a Russian and Bulgarian male given name derived from the Greek ''Aléxios'' (), meaning "Defender", and thus of the same origin as the Latin Alexius. Similar Ukrainian and Belarusian names are romanized as Oleksii (Олексій) and Aliaksiej (Аляксей), respectively. The Russian Orthodox Church uses the Old Church Slavonic version, Alexiy or Aleksiy (Алексiй, or Алексий in modern spelling), for its Saints and hierarchs (most notably, this is the form used for Patriarchs Alexius I and Alexius II). The name became fairly popular in Russia after the baptism of Michael of Russia's son, Alexis of Russia. The common hypocoristic is Alyosha () or simply Lyosha (). These may be further transformed into Alyoshka, Alyoshenka, Lyoshka, Lyoha, Lyoshenka (, respectively), sometimes rendered as Alesha/Aleshenka in English. The form Alyosha may be used as a full first name in Bulgaria (Альоша) and Armenia. In theory, Alexia is the female f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Cottidae
The Cottidae are a family of fish in the superfamily Cottoidea, the sculpins. It is the largest sculpin family, with about 275 species in 70 genera.Kane, E. A. and T. E. Higham. (2012)Life in the flow lane: differences in pectoral fin morphology suggest transitions in station-holding demand across species of marine sculpin. ''Zoology'' (Jena) 115(4), 223–32. They are referred to simply as cottids to avoid confusion with sculpins of other families. Cottids are distributed worldwide, especially in boreal and colder temperate climates. The center of diversity is the northern Pacific Ocean. Species occupy many types of aquatic habitats, including marine and fresh waters, and deep and shallow zones. A large number occur in near-shore marine habitat types, such as kelp forests and shallow reefs. They can be found in estuaries and in bodies of fresh water. Most cottids are small fish, under in length. The earliest fossil remains of cottids are otoliths potentially assignable to ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Lake Baikal
Lake Baikal is a rift lake and the deepest lake in the world. It is situated in southern Siberia, Russia between the Federal subjects of Russia, federal subjects of Irkutsk Oblast, Irkutsk Oblasts of Russia, Oblast to the northwest and the Republic of Buryatia to the southeast. At —slightly larger than Belgium—Lake Baikal is the world's List of lakes by area, seventh-largest lake by surface area, as well as the second largest lake in Eurasia after the Caspian Sea. However, because it is also the List of lakes by depth, deepest lake, with a maximum depth of , Lake Baikal is the world's List of lakes by volume, largest freshwater lake by volume, containing of water or 22–23% of the world's fresh surface water, more than all of the North American Great Lakes combined. It is also the world's ancient lake, oldest lake at 25–30 million years, and among the clearest. It is estimated that the lake contains around 19% of the unfrozen fresh water on the planet.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Comephorus
''Comephorus'', known as the golomyankas or Baikal oilfish, are a genus comprising two species of peculiar, sculpin fishes endemic to Lake Baikal in Russia. ''Comephorus'' is the only genus in the subfamily Comephorinae. Golomyankas are pelagic fishes and the main food source for the Baikal seal. Taxonomy ''Comephorus'' was first proposed as a monospecific genus in 1800 by the French naturalist and politician Bernard Germain de Lacépède with ''Callionymus baikalensis'' as its only species. The 5th edition of ''Fishes of the World'' places this genus in the monotypic subfamily Comephorinae within the family Cottidae, the typical sculpins. Other authorities have used phylogenetic studies which have found that Baikal sculpins that were classified in the subfamilies Comephorinae and Abyssocottinae by ''Fishes of the World'' radiated from an ancestor which was likely to be within the genus '' Cottus'' and that the classification of the Baikal sculpins in a different taxon from ''Co ...

Fish Described In 1904
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...
