Nothobranchius
''Nothobranchius'' is a genus of small, freshwater killifish, classified in the family Nothobranchiidaevan der Laan, R., Eschmeyer, W.N. & Fricke, R. (2014)Family-group names of Recent fishes.''Zootaxa, 3882 (2): 1–230.'' in the order Cyprinodontiformes. There are about a hundred species in the genus, many with very small distributions. They are primarily native to East Africa from Sudan to northern South Africa, whereas a dozen species are found in the upper Congo River Basin; the greatest species richness is in Tanzania. ''Nothobranchius'' typically inhabit ephemeral pools that are filled only during the monsoon season, and show extreme life-history adaptations to survive the dry season. When their habitats dry up, the adult fish die and the eggs survive encased in the clay during the dry season. The embryos survive the dry season by entering diapause, facilitated by their specialized eggs that have a very hard chorion and are resistant to desiccation and hypoxia.Alexander Do ...

Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish, including families Aplocheilidae, Pantanodontidae, Cyprinodontidae, Fundulidae, Nothobranchiidae, Profundulidae, Aphaniidae and Valenciidae. All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as ''Kryptolebias marmoratus'', can additionally survive out of the water for several weeks. Most killifish are small, measuring from , with the largest species growing to just under . The word ''killifish'' is of uncertain origin, but is likely to have come from the Dutch ''kil'' for a kill (small stream). Although killifish is sometimes used as an English eq ...

Nothobranchius Furzeri
''Nothobranchius furzeri'', the turquoise killifish, is a species of killifish from the family Nothobranchiidae native to Africa where it is only known from Zimbabwe and Mozambique. This annual killifish inhabits ephemeral pools in semi-arid areas with scarce and erratic precipitations and have adapted to the routine drying of their environment by evolving desiccation-resistant eggs that can remain dormant in the dry mud for one and maybe more years by entering into diapause. Among vertebrates, the species has the fastest known sexual maturity – only 14 days after hatching. Due to very short duration of the rain season, the natural lifespan of these animals is limited to a few months and their captive lifespan is likewise short. More specifically, they are able to live 1–5 months in the wild (with most only living up to 2 months) and 3 to 16 months in captivity depending on the strain and environment. Turquoise killifish are the shortest-lived vertebrate kept in captivity maki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nothobranchius Rachovii
''Nothobranchius rachovii'', the bluefin notho, is a species of freshwater annual killifish from Mozambique. It can grow up to 6 cm (2.4").Mongabay â€Rainbow Nothobranch Accessed 23 January 2010. It is popular among killifish enthusiasts, who raise them from eggs in aquaria. Description Aside from the typical orange and blue variant, there is ''Nothobranchius rachovii KNP Black'', which has much darker colors, and was collected from the wild in Kruger National Park, South Africa in 1984, and ''Nothobranchius rachovii var. Red'', which has a red head with turquoise highlights. The females of all varieties are more neutrally colored. This shows sexual dimorphism among these fish. Distribution ''Nothobranchius rachovii'' ''sensu stricto'' is found in the floodplain of the lower Zambezi and also in the floodplain of the Pungwe River. Diet ''N. rachovii'' are benthopelagic, feeding on zooplankton and other small organisms living at the bottom of the water (benthos). Habit ...

Nothobranchius Albertinensis
''Nothobranchius albertinensis'' is a species of brightly colored seasonal killifish in the family Nothobranchiidae. This species is endemic to seasonal freshwater habitats in north-western Uganda. It is currently known from ephemeral pools and marshes associated with the Albert Nile drainage, as well as small river systems draining into the north-eastern part of Lake Albert. The small and colourful ''Nothobranchius'' fishes inhabit ephemeral habitats in freshwater wetlands of Africa and have extreme life-history adaptations. Members of the genus are recognized as seasonal fishes, with all known species having an annual or semi-annual life cycle, a key adaptation to reproduce in the seasonally arid savannah biome and allowing their eggs to survive the periodic drying up of the seasonal natural habitats. ''Nothobranchius'' fishes are subject to high levels of threat, with 72% of the species falling into one of the Threatened Red List categories, as a consequence of habitat des ...

Nothobranchiidae
Nothobranchiidae are a Family (biology), family of Osteichthyes, bony fishes containing roughly 300 species, also known as African rivulines. They are small killifish, usually measuring about . They are limited to Africa, living in fresh water but being also somewhat salt-tolerant. They are also found in muddy or brackish water. Some species are kept as aquarium pets. They have frilly fins and many are brightly colored. They were formerly included in the family Aplocheilidae (which was later limited to Madagascar, Malagasy, Seychelles, Seychellean and Asian species); a return to that broader family has recently been suggested. Members of genus ''Nothobranchius'' are found in mud pools on the plains of Africa, a habitat shared by no other fish except the lungfishes. Their life cycle is only a year long, and they die when the pools dry up, however the species survives because their eggs remain inactive (in diapause) in the dry bottom Substrate (biology), substrate throughout the dr ...
