Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinid
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Kuban River
The Kuban; Circassian: Псыжъ, ''Psyẑ'' or Псыжь, ''Psyź'' ; abq, Къвбина, ''Q̇vbina'' ; Karachay–Balkar: Къобан, ''Qoban''; Nogai: Кобан, ''Qoban'') is a river in Russia that flows through the Western Caucasus and drains into the Sea of Azov. The Kuban runs mostly through Krasnodar Krai for , but also in the Karachay–Cherkess Republic, Stavropol Krai and the Republic of Adygea. The Kuban flows north and west from its source near Mount Elbrus in the Caucasus Mountains, eventually reaching Temryuk Bay in the Sea of Azov. It is navigable up to Krasnodar. Major cities on the river are Karachayevsk, Cherkessk, Nevinnomyssk, Armavir, Novokubansk, Kropotkin, Ust-Labinsk, Krasnodar and Temryuk. Despite its name, Slavyansk-na-Kubani lies not on the Kuban River, but on its distributary the Protoka. Geography and hydrology The river originates on the slopes of Mount Elbrus and forms at the merger of its two tributaries, Ullukam and Uchkulam; ...
