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] |
Cyprinidae
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 ...

The Nakdonggang River or Nakdonggang () is the longest river in South Korea, and passes through major cities such as Daegu and Busan. It takes its name from its role as the eastern border of the Gaya confederacy during Korea's Three Kingdoms Era. Geography The Nakdonggang flows from the Taebaek Mountains to the South Sea or Korean Strait, which separates Korea from Japan. The river originates from the junction of the Cheolamcheon and Hwangjicheon streams in Dongjeom-dong, Taebaek city, Gangwon province. From there to its mouth it winds for about . The width of the river ranges from only a few metres in its upper reaches, to several hundred metres towards its estuary. Major tributaries include the Yeong, Geumho, and Nam rivers.

''Tanakia'' is a genus of cyprinid fish, consisting of five species that occurs in Eastern Asia. The type species is the ''Tanakia limbata''. Genus is named for Shigeho Tanaka (1878-1974), “accomplished” ichthyologist of the Imperial University of Tokyo, who described ''Tanakia shimazui'' in 1908 and ''Pseudorhodeus tanago'' in 1909. Species There are currently 9 species of this genus: * ''Tanakia himantegus'' ( Günther, 1868) * ''Tanakia koreensis'' ( I. S. Kim & C. H. Kim, 1990) * ''Tanakia lanceolata'' (Temminck & Schlegel, 1846) * ''Tanakia latimarginata'' (Kim, Jeon & Suk, 2014) * ''Tanakia limbata'' (Temminck & Schlegel, 1846) (Oily bitterling) * ''Tanakia shimazui'' ( S.
