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 Ditte
''Nothobranchius ditte'' is a species of brightly colored seasonal killifish in the family Nothobranchiidae, belonging to the '' Nothobranchius brieni'' species complex. It is endemic to freshwater habitats in the south-eastern parts of the Democratic Republic of the Congo. Adult males reach a length of about 40–42 mm, but the females are slightly smaller. The species is a semi-annual killifish. They inhabit ephemeral pools filled by rainwater during the monsoon season, being adapted to the alteration of dry and wet seasons. As with all members of the genus ''Nothobranchius'', they show extreme life-history adaptations: their embryos survive by entering a three or four month long diapause, within eggs that have a very hard chorion and are resistant to desiccation and hypoxia. When the habitats dry up, the adult fish die and the eggs survive encased in the clay during the dry season. Type locality and type material The type locality is stated as "Ephemeral swamps of th ...

Alexandra Raspopova
Alexandra () is a female given name of Greek origin. It is the first attested form of its variants, including Alexander (, ). Etymologically, the name is a compound of the Greek verb (; meaning 'to defend') and (; GEN , ; meaning 'man'). Thus it may be roughly translated as "defender of man" or "protector of man". The name Alexandra was one of the epithets given to the Greek goddess Hera and as such is usually taken to mean "one who comes to save warriors". The earliest attested form of the name is the Mycenaean Greek ( or //), written in the Linear B syllabic script.Tablet MY V 659 (61). Alexandra and its masculine equivalent, Alexander, are both common names in Greece as well as countries where Germanic, Romance, and Slavic languages are spoken.
