Nothobranchius Polli

''Nothobranchius'' is a genus of small, freshwater killifish, classified in either the family Nothobranchiidaevan der Laan, R., Eschmeyer, W.N. & Fricke, R. (2014)

Comparative morphology and classification of South American cynopoeciline killifishes (Cyprinodontiformes: Aplocheilidae), with notes on family-group names used for aplocheiloids.
''Vertebrate Zoology, 66 (2): 125-140.'' in the order Cyprinodontiformes. There are many species: as of 2018 there are more than 70 species, many with very small distributions. They are primarily native to East Africa from Sudan to northern South Africa, but half a dozen species are found in the upper Congo River Basin and two species ('' N. rubroreticulatus'' and '' N. thierryi'') are from west-central Africa; 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 Dorn, Zuzana Musilová, Matthias Platzer, Kathrin Reichwald and Alessandro Celler (2014
The strange case of East African annual fishes: aridification correlates with diversification for a savannah aquatic group?
''BMC Evolutionary Biology'' 14:210. DOI: 10.1186/s12862-014-0210-3 These species reach maturity very quickly once diapause is broken and have a very short life span; one species, '' Nothobranchius furzeri'', reaches maturity in 17 days and seldom lives beyond 6 months.

Etymology

From Greek νοθοσ / ''nothos'': false, spurious, and βράγχια / ''bránchia'': gill.
