Odaxothrissa, the fangtooth pellonulines, is a genus of fresh-water fish in the family Dorosomatidae. There are currently three recognized species in this genus, all of which are found in tropical Africa.
The Poeciliidae are a family of freshwater fishes of the order Cyprinodontiformes, the tooth-carps, and include well-known live-bearing aquarium fish, such as the guppy, molly, platy, and swordtail. The original distribution of the family was the Southeastern United States to north of Río de la Plata, Argentina, and Africa, including Madagascar. Due to release of aquarium specimens and the widespread use of species of the genera Poecilia and Gambusia for mosquito control, though, poeciliids can today be found in all tropical and subtropical areas of the world. In addition, Poecilia and Gambusia specimens have been identified in hot springs pools as far north as Banff, Alberta.
George Albert Boulenger 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.
Fangtooths are beryciform fish of the family Anoplogastridae that live in the deep sea. The name is from the Greek anoplo, meaning "unarmed", and γαστήρ, meaning "stomach". With a circumglobal distribution in tropical and cold-temperate waters, the family contains only two very similar species in one genus, with no known close relatives.
Notothenioidei is one of 19 suborders of the order Perciformes. The group is found mainly in Antarctic and Subantarctic waters, with some species ranging north to southern Australia and southern South America. Notothenioids constitute approximately 90% of the fish biomass in the continental shelf waters surrounding Antarctica.
Buccochromis is a genus of relatively large haplochromine cichlids endemic to Lake Malawi and the upper Shire River in East Africa.
Astroblepus is a genus of fish in the family Astroblepidae found in South America and Panama. This genus is the only member of its family. These catfishes are primarily found in torrential streams in the Andean area. Astroblepus pholeter and A. riberae are troglobites adapted to living in subterranean water systems. These species are typically small, less than 10 cm (4 in). The largest species reaches 30 cm (1 ft). These fish have suckermouths like those of loricariids. They have two pairs of barbels, maxillary and nasal. The dorsal fin spine lacks a locking mechanism. These fish also have odontodes, tiny teeth on their skin. All species exhibit a conical, pointy type on their fin rays like that found in other loricarioids; other species also exhibit a blunt type that is only found on their skin.
Rhamphochromis is a genus of East African haplochromine cichlids endemic to the Lake Malawi basin, also including Lake Malombe, Lake Chilingali, Chia Lagoon and upper Shire River. They mainly occur in offshore open waters, but a few species also near the coast. They are piscivores that typically feed on lake sardines and small utaka cichlids.
Haplochromis is a ray-finned fish genus in the family Cichlidae. It has been used as the default "wastebin taxon" for Pseudocrenilabrinae cichlids of the East African Rift, and as such became the "largest" fish "genus". Many of these cichlids are popular aquarium fishes; like similar Haplochromini they are known as "haplos", "happies" or "haps" among aquarium enthusiasts.
Pseudomystus is a genus of catfishes of the family Bagridae.
Chelaethiops minutus is a species of ray-finned fish in the family Cyprinidae. It is endemic to Lake Tanganyika and its outflow, the Lukuga River and is found in Burundi, Democratic Republic of the Congo, Tanzania, and Zambia.
The Lake Tanganyika sardine is a species of freshwater fish in the family Dorosomatidae which was endemic to Lake Tanganyika but which has now been introduced to other lakes in Africa as a food source. It is monotypic within the genus Limnothrissa. It and the Lake Tanganyika sprat are known collectively as kapenta.
Pimelodella is a genus of three-barbeled catfishes.
Tylochromis is a genus of African fishes in the family Cichlidae. They are the only members of the tribe Tylochromini. Many of the species are endemic to the Congo River Basin, but species also are found in Lake Tanganyika, Cameroon, Nigeria, and West Africa from Ghana to Gambia.
Microthrissa is a genus of sprats in the herring family, Dorosomatidae, which is endemic to Africa. There are five recognized species in the genus.
Potamothrissa is a genus of fish in the family, Dorosomatidae, which is native to Africa. It currently contains three species.
Melanostomias is a genus of barbeled dragonfishes.
Spicara is a genus of picarels native to the eastern Atlantic Ocean and the western Indian Ocean.
Pagetopsis is a genus of marine ray-finned fish belonging to the family Channichthyidae, the crocodile icefishes. The species in this genus are found in the Southern Ocean.
Trematomus is a genus of marine ray-finned fishes, belonging to the family Nototheniidae, the notothens or cod icefishes. These fishes occur in the Southern Ocean.
Microthrissa royauxi, the royal sprat, is a species of pelagic, freshwater fish from the herring family Clupeidae which is found in the Congo River basin in west Africa. It was described in 1902 by the Belgian-British zoologist George Albert Boulenger. It is of limited importance as a food fish in subsistence fisheries and its conservation status is Least Concern.
