Cyprinodont
Pupfish are a group of small killifish belonging to ten genus, genera of the family Cyprinodontidae of ray-finned fish. Pupfish are especially noted for being found in extreme and isolated situations. They are primarily found in North America, South America, and the Caribbean region, but ''Aphanius'' species are from southwestern Asia, northern Africa, and southern Europe. As of August 2006, 120 nominal species and 9 subspecies were known. Several pupfish species are extinct and most extant species are listed. In the U.S., the most well-known pupfish species may be the Devils Hole pupfish, Devil's Hole Desert Pupfish, native to Devils Hole, Devil's Hole on the Nevada side of Death Valley National Park. Since 1995 the Devil's Hole Pupfish has been in a nearly steady decline, where it was close to extinction at 35–68 fish in 2013. The common name is said to derive from the mating habits of the males, whose activities vaguely resemble puppies at play. Carl Leavitt Hubbs, Carl L. ...

Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish (including families Aplocheilidae, Cyprinodontidae, Fundulidae, Profundulidae 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 killies are small fish, 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 equivalent to the taxonomical term ''Cyprinodontidae'', s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megupsilon Aporus - Last Male
The Catarina pupfish (''Megupsilon aporus'') was a diminutive species of fish in the family Cyprinodontidae, first described in 1972. It was endemic to a spring in Nuevo León, Mexico. In an attempt of saving the rapidly declining species, some were brought into captivity in the late 1980s and early 1990s, but it proved very difficult to maintain. In 1994 it became extinct in the wild. Gradually the captive populations also perished. The last male died in 2014 (pictured in inset) and the species became extinct. In addition to its small size, it was characterized by absence of pelvic girdle and pelvic fins, novel male reproductive behavior of jaw-nudging, a darkened dorsal patch, and by having different numbers of chromosomes in male and female fish due to a recent chromosomal fusion event. In 2013, its behavior was described based on very limited field observations of the previous wild population and more detailed observations in aquaria. Extinction The Catarina pupfish is extin ...

Garmanella Pulchra
The Yucatan flagfish (''Garmanella pulchra''), also known as the snakeskin killifish, is a species of pupfish from the family Cyprinodontidae. It is found in the coastal waters (both fresh and brackish) of the Yucatan Peninsula, in Mexico and Belize. This species grows to a length of TL and is found in the aquarium trade. This species was described by Carl Leavitt Hubbs in 1936 with the type locality given as east of Progreso, Yucatán, Mexico. It is the only known member of its genus. The name of the genus commemorates the American ichthyologist Samuel Garman (1843-1927) who was working on a revision of his 1895 monograph on the Cyprinodontidae at the time of his death. It is sometimes treated as a junior synonym of ''Jordanella''. The Yucatan flagfish is found in coastal brackish water systems and inland freshwaters with hard water over substrates of marl, sand, decomposing vegetation, rocks and mud. It is mainly herbivorous, its diet largely being made up of microalgae, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyprinodontiformes
Cyprinodontiformes is an order (biology), order of Actinopterygii, ray-finned fish, comprising mostly small, freshwater fish. Many popular aquarium fish, such as killifish and Poeciliidae, live-bearers, are included. They are closely related to the Atheriniformes and are occasionally included with them. A colloquial term for the order as a whole is toothcarps, though they are not actually close relatives of the true carps – the latter belong to the superorder Ostariophysi, while the toothcarps are Acanthopterygii. The families of Cyprinodontiformes can be informally divided into three groups based on reproductive strategy: Viviparity, viviparous and Ovoviviparity, ovoviviparous (all species give live birth), and Oviparity, oviparous (all species are egg-laying). The live-bearing groups differ in whether the young are carried to term within (ovoviviparous) or without (viviparous) an enclosing eggshell.

Bernard Germain De Lacépède
Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède or La Cépède (; 26 December 17566 October 1825) was a French naturalist and an active freemason. He is known for his contribution to the Comte de Buffon's great work, the ''Histoire Naturelle''. Biography Lacépède was born at Agen in Guienne. His education was carefully conducted by his father, and the early perusal of Buffon's Natural History ('' Histoire naturelle, générale et particulière'') awakened his interest in that branch of study, which absorbed his chief attention. His leisure he devoted to music, in which, besides becoming a good performer on the piano and organ, he acquired considerable mastery of composition, two of his operas (which were never published) meeting with the high approval of Gluck; in 1781–1785 he also brought out in two volumes his ''Poétique de la musique''. Meantime he wrote two treatises, ''Essai sur l'électricité'' (1781) and ''Physique générale et particuliè ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinodon
''Cyprinodon'' is a genus of pupfishes found in waters that range from fresh to hypersaline. The genus is primarily found in Mexico, the Caribbean Islands and southern United States (Arizona, California, Florida, Nevada, New Mexico, Oklahoma and Texas), but ''C. variegatus'' occurs as far north as Massachusetts and along the entire Gulf of Mexico coastline, and ''C. dearborni '' and ''C. variegatus'' are found in northern South America.Martin, C. H., and P. C. Wainwright (2013). ''Multiple Fitness Peaks on the Adaptive Landscape Drive Adaptive Radiation in the Wild.'' Science 339(6116): 208-211. Many species have tiny ranges and are highly threatened, in some cases already extinct. ''Cyprinodon'' are small; the largest reaches in length and most other species only reach about half that size. Distribution and habitat A few ''Cyprinodon'' species have quite large ranges, notably '' C. variegatus'', but the vast majority have small ranges, typically restricted to one or two Mexi ...

Giovanni Domenico Nardo
Giovanni Domenico Nardo (4 March 1802 – 7 April 1877) was an Italian naturalist from Venice, although he spent most of his life in Chioggia, home port of the biggest fishing flotilla of the Adriatic. He learned taxidermy and specimen preparation from his uncle, an abbot. He went in a high school in Udine and studied medicine in Padua, where he reorganized the zoological collections. In 1832 he reorganized the invertebrate collection at the Imperial Natural History Museum in Vienna and in 1840 he became Fellow of the Istituto Veneto di Scienze, Lettere ed Arti, an academy whose aim is "to increase, promulgate, and safeguard the sciences, literature and the arts". Nardo wrote hundreds of scientific publications ranging from medicine and social sciences, philology, technology, physics, but mostly on Venetian and Adriatic zoology. In marine biology, Nardo wrote on algae, marine invertebrates, fishes and sea turtles. A vast collection of his manuscripts and his personal library is pre ...

Ovoviviparity
Ovoviviparity, ovovivipary, ovivipary, or aplacental viviparity is a term used as a "bridging" form of reproduction between egg-laying oviparous and live-bearing viviparous reproduction. Ovoviviparous animals possess embryos that develop inside eggs that remain in the mother's body until they are ready to hatch. The young of some ovoviviparous amphibians, such as ''Limnonectes larvaepartus'', are born as larvae, and undergo further metamorphosis outside the body of the mother. Members of genera ''Nectophrynoides'' and ''Eleutherodactylus'' bear froglets, not only the hatching, but all the most conspicuous metamorphosis, being completed inside the body of the mother before birth. Among insects that depend on opportunistic exploitation of transient food sources, such as many Sarcophagidae and other carrion flies, and species such as many Calliphoridae, that rely on fresh dung, and parasitoids such as tachinid flies that depend on entering the host as soon as possible, the e ...
