George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

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 ...

Nyong River
The Nyong (formerly german: Yong) is a river in Cameroon. The river flows approximately to empty into the Gulf of Guinea. Course The Nyong originates east of the town of Abong-Mbang, where the northern rain forest feeds it. The river's length is almost parallel to the lower reaches of the Sanaga River. Its mouth is in Petit Batanga, south-southwest of Edéa. In two places, Mbalmayo and Déhané, the river has huge rapids. The first of the river, between Abong-Mbang and Mbalmayo, are navigable for small boats from April to November. Hydrology The flow of the river as measured at Déhané in m³/s: Transport The town of Mbalmayo, which has a railhead, lies on the north bank of this river. The towns of Akonolinga Akonolinga is a town and commune situated in Cameroon's Centre Province, with a population of roughly 21,300.

Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa. It is bordered by Nigeria to the west and north; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south. Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Its nearly 27 million people speak 250 native languages. Early inhabitants of the territory included the Sao civilisation around Lake Chad, and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area ''Rio dos Camarões'' (''Shrimp River''), which became ''Cameroon'' in English. Fulani soldiers founded the Adamawa Emirate ...

Cuanza River
The Kwanza River, also known as the Coanza, the Quanza, and the Cuanza, is one of the longest rivers in Angola. It empties into the Atlantic Ocean just south of the national capital Luanda. Geography The river is navigable for about from its mouth, located south of Luanda. Its tributaries included the Cutato and Lucala. History The river's navigable lower course was the original route of Portugal invasion into northern Angola. The Capanda Dam in Malanje Province was finished in 2004, providing hydroelectric power to the region and assisting its irrigation. The Cambambe Dam and the Lauca Dam were also constructed on the river. The Caculo Cabaça Hydroelectric Power StationCaculo Cabaça Dam is under construction with estimated completion in 2024. The ''Barra do Kwanza'', the mouth of the river is gradually being developed for tourism, including a golf course. The Church of Nossa Senhora da Victoria stands near the banks of the Kwanza River in Massanganu, Province of ...

Cypriniformes
Cypriniformes is an order of ray-finned fish, including the carps, minnows, loaches, and relatives. Cypriniformes is an Order within the Superorder Ostariophysi consisting of "Carp-like" Ostariophysins. This order contains 11-12 families, although some authorities have designated as many as 23, over 400 genera, and more than 4,250 species, with new species being described every few months or so, and new genera being recognized frequently.Eschmeyer, W.N., Fong, J.D. (2015Species by family/subfamilyin the Catalog of Fishes, California Academy of Sciences (retrieved 2 July 2015) They are most diverse in southeastern Asia, and are entirely absent from Australia and South America.Nelson (2006) At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo. Their closest living relatives are the Characiformes ( characins and allies), the Gymnotiformes (electric eel and American knifefishes), and the Siluriformes (catfishes).

Fish Of Africa
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Taxa Named By George Albert Boulenger
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ...
