Pseudobarbus
''Pseudobarbus'' is a ray-finned fish genus in the family Cyprinidae. The type species is Burchell's redfin (''P. burchelli''). The scientific name is derived from the Ancient Greek ''pseudes'' ("false") and the Latin word ''barbus'' ("beard", in reference to the barbels of barbs). This genus contains some (and might contain all) of the South African redfins. It was originally proposed as a subgenus, but has since been found worthy of recognition as a full genus. This genus is restricted to southern Africa; all of its species were formerly placed in ''Barbus'', the genus of typical barbels and their relatives. One taxon was originally described as ''P. leonhardi'' – this, however, was a European fish for which the genus was erroneously proposed anew. It has since turned out to be nothing other than the barbel '' B. peloponnesius''. Species and systematics ''Pseudobarbus'' was placed in the paraphyletic "subfamily" Barbinae by those that recognize that group, but if not in ...

Pseudobarbus Afer
The Eastern Cape redfin (''Pseudobarbus afer'') is an African freshwater fish species in the family (biology), family Cyprinidae, this appears to be a species complex rather than a single species. It is endemism, endemic to the Sundays River, Sundays, Swartkops River, Swartkops and Baakens River, Baakens river systems of the Eastern Cape, South Africa, the fish in other rivers in the region have been suggested to belong to different species with four different lineages recognised, a forest lineage which appears to be more closely related to ''Pseudobarbus phlegethon'' of the Olifants River (Western Cape), Olifants River than the other lineages traditionally classified within ''P. afer'', the other lineages are the "St Francis" lineage which occurs in the rivers flowing into St Francis Bay and has been given the name ''Pseudobarbus swartzi'', the Krom lineage ''Pseudobarbus senticeps'' from the Krom River system and the "Mandela" lineage ''Pseudobarbus afer'' ''sensu stricto''.

Pseudobarbus Asper
The smallscale redfin (''Pseudobarbus asper'') is a freshwater fish in the family Cyprinidae which is endemic to South Africa. It is threatened by habitat destruction and the impact of invasive species. Description Its meristic data are that there are three-four dorsal fin spines and 7 rays while the nail fin has three spines and five rays and the lateral line has 37-40 small scales. It has a single pair of barbels and the males develop dark red fins and tubercles on the head when breeding. It grows to around total length. Distribution ''Pseudobarbus asper'' occurs in the arid Karoo region of South Africa in the Gamtoos and Gourits River systems of the Eastern Cape in South Africa. Biology The smallscale redfin is found in turbid, eutrophic waters which have soft silty beds or over boulders to boulder in the Karoo region of South Africa. Its small size is understood to be an adaptation to the highly variable environment this fish inhabits, making it able to exploit food resou ...

Burchell's Redfin
Burchell's redfin (''Pseudobarbus burchelli''), also known as the Tradouw redfin, Tradou redfin or Breede redfin, is an African freshwater fish species in the family Cyprinidae. ''P. burchelli'' is the type species of its genus ''Pseudobarbus'', and like all of these is tetraploid. The Berg River redfin (''P. burgi'') is a very close relative. It is endemic to the Western Cape Province of South Africa, where it occurs in the Moeras and Tradouw Rivers. Whether the similar fishes from the Breede River and Heuningnes River are also ''P. burchelli'' is undetermined.Swartz & Impson (2007) Two populations are known with certainty, one in the Moeras River at Barrydale and one at the Tradouw River at Tradouws Pass. During summer, low water levels cut off gene flow between these two. The species inhabits deeper sections of the rivers' somewhat peaty water. Other fish are rare, and in Burchell's redfin's range these seem to consist of the introduced bluegill (''Lepomis macrochirus'') a ...

Barbus
''Barbus'' is a genus of ray-finned fish in the family Cyprinidae. The type species of ''Barbus'' is the common barbel, first described as ''Cyprinus barbus'' and now named ''Barbus barbus''. ''Barbus'' is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part (including the type species of ''Barbus''). Description and uses Their common names – barbs and barbels – refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however. The large ''Barbus'' barbs are also often eaten in their native range. The smaller barbs are in some cases traded as aquarium fish. Some are quite significant, but as a whole, the genus is not yet as well represented in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 1,780 species divided into 166 valid genera. Cyprinids range from about 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, or ''agastric'', 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 to identify spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbus Peloponnesius
''Barbus peloponnesius'' is a ray-finned fish species in the family Cyprinidae. The western Balkan barbel (''B. rebeli'') is sometimes included in the present species. It is found only in Greece,Bulgaria and Albania. Its natural habitats are rivers and freshwater lakes. It is not considered a threatened species by the IUCN The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status ..., however a subspecies, ''Barbus peloponnesius petenyi'', is protected and considered threatened. The latter can be found in the Danube basin, particularly in areas of the Duna-Ipoly National Park in Hungary.

Southern Africa
Southern Africa is the southernmost region of Africa. No definition is agreed upon, but some groupings include the United Nations geoscheme for Africa, United Nations geoscheme, the intergovernmental Southern African Development Community, and the #Definitions and Usage, physical geography definition based on the physical characteristics of the land. The most restrictive definition considers the region of Southern Africa to consist of Botswana, Eswatini, Lesotho, Namibia, and South Africa, while other definitions also include several other countries from the area. Defined by physical geography, Southern Africa is home to several river systems; the Zambezi, Zambezi River is the most prominent. The Zambezi flows from the northwest corner of Zambia and western Angola to the Indian Ocean on the coast of Mozambique. Along the way, it flows over Victoria Falls on the border between Zambia and Zimbabwe. Victoria Falls is one of the largest waterfalls in the world and a major tourist a ...

Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he greatly increased ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach t ... of freshwater fish.
