Labeobarbus
''Labeobarbus'' is a mid-sized ray-finned fish genus in the family Cyprinidae. Its species are widely distributed throughout eastern Africa and especially southern Africa, but also in Lake Tana in Ethiopia. A common name, in particular for the southern species, is yellowfish. The scientific name refers to the fact that these large barbs recall the fairly closely related "carps" in the genus '' Labeo'' in size and shape. As far as can be told, all ''Labeobarbus'' species are hexaploid.de Graaf ''et al.'' (2007), IUCN (2009) One species, '' L. microbarbis'' from Rwanda, is known to have gone extinct in recent times. Systematics Like many other "barbs", it was long included in ''Barbus''. It appears to be a fairly close relative of the typical barbels and relatives – the genus ''Barbus'' proper – but closer still to the large Near Eastern species nowadays separated in '' Carasobarbus''. ''Barbus'' has been split to account for the improved phylogenetic knowledge which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Tana
Lake Tana (; previously transcribed Tsana) is the largest lake in Ethiopia and a source of the Blue Nile. Located in Amhara Region in the north-western Ethiopian Highlands, the lake is approximately long and wide, with a maximum depth of , and an elevation of . Lake Tana is fed by the Gilgel Abay, Reb River, Reb and Gumara River, Gumara rivers. Its surface area ranges from , depending on season and rainfall. The lake level has been regulated since the construction of the control weir where the lake discharges into the Blue Nile. This controls the flow to the Blue Nile Falls (Tis Abbai) and hydro-power station. In 2015, the Lake Tana region was nominated as a UNESCO Biosphere Reserve recognizing its national and international natural and cultural importance. Overview Lake Tana was formed by volcanic activity, blocking the course of inflowing rivers in the early Pleistocene epoch, about 5 million years ago. The lake was originally much larger than it is today. Seven large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Labeobarbus Reinii
The giant Atlas barbel (''Atlantor reinii'') was a ray-finned fish species in the family Cyprinidae. It was the only species in the genus ''Atlantor'' but it is now thought to be extinct. It was previously considered to be fairly close to the core group around the typical barbels (''Barbus'', ''Luciobarbus'' and ''Messinobarbus''). It was also thought to be closer still to ''Carasobarbus'' and the yellowfish (''Labeobarbus''), and to be either a lineage of the former, or part of a distinct genus, or included in the latter (maybe together with the former). Initially classified in the genus ''Barbus'', it was transferred to the genus ''Labeobarbus'' in 2010. However, in 2023 this taxon was reclassified in the monospecific genus ''Atlantor'' within the subfamily Torinae. The specific name honours the geographer, author and traveler Johannes Justus Rein (1835-1918), who, with Karl von Fritsch, collected the type from the Tensift River in Morocco. It was endemic to Morocco, where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Labeobarbus Microbarbis
''Labeobarbus microbarbis'' is an extinct species of cyprinid fish. It was endemic to Lake Luhondo in Rwanda. The fish has not been recorded since alien fish species of ''Tilapia'' and ''Haplochromis'' were introduced to the lake. Despite regular surveys ''L. micronarbis'' has not been seen for over fifty years and has thus been classed as extinct. However, it may be that the original holotype A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of s ... represents a hybrid rather than a valid species and so the taxonomic status of the species is doubtful.

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] |
Barbel (fish)
Barbels are a group of carp-like freshwater fish, almost all of the genus ''Barbus''. They are usually found in gravel and rocky-bottomed moderate-flowing rivers with high dissolved oxygen content, known as the ''European river zonation#Barbel zone, Barbel zone''. A typical adult barbel can range from in length and weigh between and , depending on species. The name barbel derived from the Latin ''barba'', meaning beard, a reference to the two pairs of barbel (anatomy), barbels, a longer pair pointing forwards and slightly down positioned, on the side of the mouth. Fish described as barbels by English-speaking people may not be known as barbels in their native language, although the root of the word may be similar. For instance, the Mediterranean barbel (''Barbus meridionalis'') is known as ''barbeau méridional'' or ''barbeau truité'' in France, but also as ''drogan'', ''durgan'', ''tourgan'', ''turquan'' and ''truitat''. Europe ''Barbus barbus'', is found throughout northern a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carasobarbus
''Carasobarbus'', the himris, is a small genus of ray-finned fishes in the family Cyprinidae. Its species are found in rivers, streams, lakes and ponds in Western Asia and Northwest Africa. ''C. canis'' can reach in total length, but most other species are up to around half or one-quarter of that size. Like many other "barbs", it was long included in ''Barbus''. It appears to be a fairly close relative of the typical barbels and relatives – the genus ''Barbus'' proper –, but closer still to the large hexaploid species nowadays separated in '' Labeobarbus''. Because of the improved phylogenetic knowledge which indicates ''Barbus'' was highly paraphyletic in its wide circumscription –, ''Carasobarbus'' and some other closely related "barbs" (e.g. '' "Barbus" reinii'') may be included in ''Labeobarbus'' to avoid a profusion of very small genera.de Graaf ''et al.'' (2007) This genus is now classified in the subfamily Torinae. Species ''Carasobarbus'' contains t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barb (fish)
A barb is one of various ray-finned fish species in a non-phylogenetic group, with members in the family (biology), family Cyprinidae, and especially the genera ''Barbus'' and ''Puntius'', but many others also. They were formerly united with the barbel (fish), barbels in the subfamily Barbinae but that group is paraphyletic with the Cyprininae. If the Labeoninae are recognized as distinct, many small African "barbs" would probably, however, warrant recognition as a new subfamily. The Root (linguistics), root of the word "barb" is common in cyprinid names of European languages, from the Latin ''barba'' ("beard") (Concise Oxford Dictionary, COD): * ''barb'' from Catalan * ''barbi'' from Finnish * ''barbo'' from Spanish * ''barbeau'' from French * ''barbo'' from Italian and many others. This is in reference to the barbel (anatomy), barbels which are prominently seen around the mouth of many "barbs". Genera Genera that contain species with common names including "barb": * ''Borde ...

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] |
Near East
The Near East () is a transcontinental region around the Eastern Mediterranean encompassing the historical Fertile Crescent, the Levant, Anatolia, Egypt, Mesopotamia, and coastal areas of the Arabian Peninsula. The term was invented in the 20th century by modern Western geographers and was originally applied to the Ottoman Empire, but today has varying definitions within different academic circles. The term ''Near East'' was used in conjunction with the ''Middle East'' and the ''Far East'' (China and beyond), together known as the "three Easts"; it was a separate term from the ''Middle East'' during earlier times and official British usage. As of 2024, both terms are used interchangeably by politicians and news reporters to refer to the same region. ''Near East'' and ''Middle East'' are both Eurocentrism, Eurocentric terms. According to the National Geographic Society, the terms ''Near East'' and ''Middle East'' denote the same territories and are "generally accepted as comprisin ...

Extinct
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Rwanda
Rwanda, officially the Republic of Rwanda, is a landlocked country in the Great Rift Valley of East Africa, where the African Great Lakes region and Southeast Africa converge. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi, and the Democratic Republic of the Congo. With a comparatively high elevation, Rwanda has been given the sobriquet "land of a thousand hills" (), with its geography dominated by mountains in the west and savanna to the southeast, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year. It is the most densely populated mainland African country; among countries larger than 10,000 km2, it is the third-most densely populated country in the world. Its Capital city, capital and largest city is Kigali. Hunter-gatherers settled the territory in the Stone Age, Stone and Iron Ages, followed later by Bantu peoples. The population coalesce ...
