Neolebias is a genus of small distichodontid freshwater fishes found in Africa. [1]
There currently 12 recognized species: [1]
Bichirs and the reedfish comprise Polypteridae, a family of archaic ray-finned fishes and the only family in the order Polypteriformes.
Polypterus is a genus of freshwater fish in the bichir family (Polypteridae) of order Polypteriformes. The type species is the Nile bichir. Fish in this genus live in various areas in Africa. Polypterus is the only known vertebrate to have lungs, but no trachea.
Oreochromis is a large genus of oreochromine cichlids, fishes endemic to Africa and the Middle East. A few species from this genus have been introduced far outside their native range and are important in aquaculture. Many others have very small ranges; some are seriously threatened, and O. ismailiaensis and O. lidole possibly are extinct. Although Oreochromis primarily are freshwater fish of rivers, lakes and similar habitats, several species can also thrive in brackish waters and some even survive in hypersaline conditions with a salinity that far surpasses that of seawater. In addition to overfishing and habitat loss, some of the more localized species are threatened by the introduction of other, more widespread Oreochromis species into their ranges. This is because they—in addition to competing for the local resources—often are able to hybridize.
Labeo is a genus of carps in the family Cyprinidae. They are found in freshwater habitats in the tropics and subtropics of Africa and Asia.
Mastacembelus is a genus of many species of spiny eel fish from the family Mastacembelidae. They are native to Africa and Asia. Most are found in rivers and associated systems, but there are also species in other freshwater habitats and a particularly rich radiation is found in the Lake Tanganyika basin with 15 species. A few species can even occur in brackish water.
Synodontis is the largest genus of mochokid catfishes. It is the biggest genus within the 10 genera and 190 different species in the family Mochokidae. Synodontis has over 131 different species within the genus. Synodontis are also known as squeakers, due to their ability to make stridulatory sounds through their pectoral fin spines when handled or disturbed. Synodontis make a sound that sounds like squeaking by rubbing their spines together. They do this when they have been frightened or when they become angry. Synodontis may also squeak when they are taken out of the water. These catfish are small- to medium-sized fish with many species exhibiting attractive spotted markings. Some species are also known for naturally swimming belly-up, earning the name upside-down catfish. Some of these species are Synodontis contractus and Synodontis nigriventris. While some of these species are known to swim upside down, another species, Synodontis multipunctatus, is a brood parasitic cuckoo catfish,there are two other species Synodontis petricola and Synodontis grandiops are also called brood parasitic cuckoo catfish.
Chiloglanis is a genus of upside-down catfishes native to Africa. These species have modified lips and barbels that form a suckermouth. They also have a naked (scaleless) body. Sexual dimorphism has been reported in Chiloglanis. The adult males of many of these species have elongate anal and caudal fins. Also, males may have an enlarged humeral process.
Marcusenius is a genus of the elephantfish group native to Africa. Its members are highly diverse in size, with the smallest species reaching less than 15 cm (6 in) and the largest more than 1 m (3.3 ft).
Serranochromis is a genus of relatively large, robust cichlids from freshwater habitats in mainland Southern Africa, ranging as far north as DR Congo and Tanzania, with the highest species richness in the upper Zambezi, Okavango and Congo basins. They are typically known as largemouths or, especially among fishers, breams. Serranochromis are mostly piscivores and they are important in local fisheries.
Microsynodontis is a genus of upside-down catfishes native to freshwater rivers in western Africa. The genus was originally described by British-Belgian zoologist George Albert Boulenger in 1903 based upon the type species Microsynodontis batesii. The name microsynodontis comes from the Greek word mikro, meaning small, and the Greek term synodon, meaning "with the teeth all growing together".
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.
Sargochromis is a genus of haplochromine cichlids native to freshwater habitats in Southern Africa, where found in the upper and middle Zambezi basin, Okavango delta, Cunene basin, Cuvelai basin and southeastern Congo Basin. They are typically known as happies or smallmouths. The latter name refers to their small mouth compared to their close relatives, the largemouths of the genus Serranochromis. Unlike the species in that genus which mostly feed on other fish, Sargochromis mostly feed on invertebrates, but in some species plant material is important. On occasion they will also eat small fish, and the stomachs of S. carlottae and S. codringtonii commonly contain fish scales, but whether these are already-lost scales that are picked off the bottom or they are actively bumped off large fish is unknown. Some of the species that feed heavily on aquatic snails have been used for biological pest control. Sargochromis are mouthbrooders. Depending on the exact species, they reach a maximum total length of 20 to 48 cm (8–19 in).
Clypeobarbus is a genus of small cyprinid fishes native to Africa. Most species are restricted to the Congo River Basin, but C. pleuropholis is also found in the Chad Basin, while C. bellcrossi is from the Zambezi and C. hypsolepis is from rivers in Western Africa.
Cladistia is a clade of bony fishes whose only living members are the bichirs. Their major synapomorphies are a heterocercal tail in which the dorsal fin has independent rays, and a posteriorly elongated parasphenoid.
Campylomormyrus is a genus of elephantfish in the family Mormyridae.
Petrocephalus is a genus of ray-finned fish in the family Mormyridae. All the fish species of this genus are endemic to Africa.
Alestopetersius is a genus of characins, fish found mostly in Congo River Basin in Middle Africa with one species from the lower Niger River in Nigeria. There are currently 10 described species in this genus.
William John Ansorge was a physician who worked in Angola and Uganda and is known for exploring the fauna of the African region. A large number of species have been named after him based on the specimens that he collected and sent back to England.
Enteromius is a genus of small to medium-sized cyprinid fish native to tropical Africa. Most species were placed in the genus Barbus.
Neolebias lozii, the banded neolebias, is a species of freshwater ray-finned fish within the family Distichodontidae. It is found in Africa within Zambia, inhabiting the tributary of the Kataba River, the Sianda stream, and a small tributary system in upper Zambia that joins the eastern side of the Barotse Floodplain. The species inhabits small streams near seasonally flooded plains that are bordered by open woodlands, living under dense floating mats of vegitation and emergent vegitation. It feeds on small aquatic invertebrates and grows to a length of 1.8 centimeters.
