Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus '' Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doumea
''Doumea'' is a genus of loach catfishes native to Africa. Species of ''Doumea'' have a rather large and tapered body, a pointed head, and a thin caudal peduncle. Thin bilateral osseous peaks are sometimes present on the back and the belly, and are the precursors series of osseous plates observed in the other kinds of Doumeinae. By the shape of the body, these fish are adapted to rapids. Species There are currently 9 recognized species in this genus: * ''Doumea angolensis'' Boulenger, 1906 * ''Doumea chappuisi'' Pellegrin, 1933 * ''Doumea gracila'' P. H. Skelton, 2007 * ''Doumea reidi'' Ferraris, P. H. Skelton & Vari, 2010 * ''Doumea sanaga'' P. H. Skelton, 2007 * '' Doumea skeltoni'' Ferraris & Vari, 2014 Ferraris, Jr., C.J. & Vari, R.P.

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 In the UK, railheading refers to the practice of travelling further than necessary to reach a rail service, typically by car.

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 E ...

FishBase is a global species database of fish species (specifically finfish). It is the largest and most extensively accessed online database on adult finfish on the web.Marine Fellow: Rainer Froese ''Pew Environment Group''. Over time it has "evolved into a dynamic and versatile ecological tool" that is widely cited in scholarly publications. FishBase provides comprehensive species data, including information on taxonomy, geographical distribution, biometrics and morphology, behaviour and habitats, e ...

Amphiliidae
The loach catfishes are a family, Amphiliidae, of catfishes (order Siluriformes). They are widespread in tropical Africa, but are most common in streams at high elevations; most species are able to cling to rocks in fast-flowing streams. The 13 genera contain 68 species. The family Amphiliidae has three subfamilies, Amphiliinae, Leptoglanidinae (previously misspelled Leptoglaninae), and Doumeinae. The monophyly of Amphiliidae has been questioned; one author restricts the family to the members of the subfamily Amphiliinae and transferred the other genera to a family Doumeidae. The Amphiliidae have been previously thought to be a basal taxon in the superfamily Loricarioidea, but some authors place their relationships elsewhere. Description Amphiliids are generally small catfishes with tapering, elongated bodies. The pectoral and ventral fin Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous Homology may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Fish Of Africa
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is ...
