A killifish is any of various oviparous cyprinodontiform fish. Altogether, there are some 1270 different species of killifish, the biggest family being Rivulidae, containing more than 320 species. Although killifish is sometimes used as an English equivalent to Cyprinodontidae, some species belonging to that family have their own common names, such as the pupfish and the mummichog. The name killifish is derived from the Dutch word "kilde", meaning small creek, puddle. Because of living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Like seeds, the eggs can be sent by mail without water. The adults of some species, such as Kryptolebias marmoratus, can additionally survive out of the water for several weeks. Most killies are small fish, from one to two inches, with the largest species growing to just under six inches. Some strains have a lifespan as short as several months and can thus serve as a model for biogerontological studies. Nothobranchiidae furzeri is the shortest-living vertebrate that can be bred in captivity, having a lifespan of between three to nine months. Nothobranchiidae furzeri needs much food because it grows quickly, so when food supplied is inadequate, bigger fish will eat the smaller fish.
