Nothobranchius Derhami
''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 ...

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 ...

Diapause
In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions.Tauber, M.J., Tauber, C.A., Masaki, S. (1986) ''Seasonal Adaptations of Insects''. Oxford University Press It is a physiological state with very specific initiating and inhibiting conditions. The mechanism is a means of surviving predictable, unfavorable environmental conditions, such as temperature extremes, drought, or reduced food availability. Diapause is observed in all the life stages of arthropods, especially insects. Activity levels of diapausing stages can vary considerably among species. Diapause may occur in a completely immobile stage, such as the pupae and eggs, or it may occur in very active stages that undergo extensive migrations, such as the adult monarch butterfly, ''Danaus plexippus''. In cases where the insect remains active, feeding is reduced and reproductive development is slowed or halted. Embryonic diapause, a somewhat ...

A dirk is a long-bladed thrusting dagger.Chisholm, Hugh (ed.); "Dagger", ''Encyclopædia Britannica'', 11th ed., Vol. VII, New York, NY: Cambridge University Press (1910), p. 729. Historically, it gained its name from the Highland dirk (Scottish Gaelic ) where it was a personal weapon of officers engaged in naval hand-to-hand combat during the Age of SailO'Brian, Patrick; ''Men-of-War: Life in Nelson's Navy'', New York: W. W. Norton & Co., (1974), p. 35. as well as the personal sidearm of Highlanders. It was also the traditional sidearm of the Highland Clansman and later used by the officers, pipers, and drummers of Scottish Highland regiments around 1725 to 1800 and by Japanese naval officers. Etymology The term is associated with Scotland in the Early Modern Era, being attested from about 1600. The term was spelled ''dork'' or ''dirk'' during the 17th century,Head, T.

Brian R
Brian (sometimes spelled Bryan in English) is a male given name of Irish and Breton origin, as well as a surname of Occitan origin. It is common in the English-speaking world. It is possible that the name is derived from an Old Celtic word meaning "high" or "noble". For example, the element ''bre'' means "hill"; which could be transferred to mean "eminence" or "exalted one". The name is quite popular in Ireland, on account of Brian Boru, a 10th-century High King of Ireland. The name was also quite popular in East Anglia during the Middle Ages. This is because the name was introduced to England by Bretons following the Norman Conquest. Bretons also settled in Ireland along with the Normans in the 12th century, and 'their' name was mingled with the 'Irish' version. Also, in the north-west of England, the 'Irish' name was introduced by Scandinavian settlers from Ireland. Within the Gaelic-speaking areas of Scotland, the name was at first only used by professional families of Iris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
