Cyprinodon
''Cyprinodon'' is a genus of pupfishes found in waters that range from Fresh water, 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. Evolution Based on phylogenetic evidence, ''Cyprinodon'' diverged from its closest relative, the recently extinct ''Catarina pupfish, Megupsilon'', during the Late Miocene, an ...

Devils Hole Pupfish
The Devils Hole pupfish (''Cyprinodon diabolis'') is a critically endangered species of the family Cyprinodontidae (pupfishes) found only in Devils Hole, a water-filled cavern in the US state of Nevada. It was first described as a species in 1930 and is most closely related to '' C. nevadensis'' and the Death Valley pupfish (''C. salinus''). The age of the species is unknown, with differing analyses offering ranges between one thousand and sixty thousand years. It is a small fish, with maximum lengths of up to . Individuals vary in coloration based on age and sex: males are bright metallic blue while females and juveniles are more yellow. A defining trait of this species is its lack of pelvic fins. The pupfish consumes nearly every available food resource at Devils Hole, including beetles, snails, algae, and freshwater crustaceans, with diet varying throughout the year. It is preyed on by the predaceous diving beetle species '' Neoclypeodytes cinctellus'', which was first obse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinodon Variegatus
The sheepshead minnow (''Cyprinodon variegatus''), also known as sheepshead pupfish, is a species of ray-finned fish in the family Cyprinodontidae, the pupfishes. It is found in salt marsh and estuary environments and is native to the eastern coasts of North and Central America. Description The sheepshead minnow is a deep-bodied fish growing up to a length of up to through . It is nearly half as deep as it is long, excluding its tail. It is laterally compressed with flat sides, an arched back and a small head with a flattened top. The small mouth is at the end of the snout and the teeth are large and wedge-shaped with three cusps. The pectoral fins are large and extend past the origins of the small pelvic fins. The origin of the anal fin hardly overlaps the trailing edge of the dorsal fin. The caudal peduncle is thick and the caudal fin is truncated and square-ended. The arrangement of the fins, the deep body and the tri-cuspid teeth help to distinguish this fish from the mummi ...

Pupfish
Pupfish are a group of small killifish belonging to ten 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. 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, native to Devils Hole on the Nevada side of Death Valley National Park. Since 1995 the Devils 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 L. Hubbs, a prominent ichthyologist and one of the first people to take an interest in them, coined the name after he observed their "playful" circling and tusslin ...

Cyprinodon Radiosus
The Owens pupfish (''Cyprinodon radiosus'') is a rare species of fish in the family Cyprinodontidae, the pupfish. It is Endemism, endemic to California in the United States, where it is limited to the Owens Valley. It is a federally listed endangered species of the United States. This pupfish is up to long, the largest males sometimes longer. The male is blue-gray, turning bright blue during spawning. The female is greenish brown with a silvery or whitish belly.Pister, E. P. (2001)Threatened fishes of the world: ''Cyprinodon radiosus'' Miller, 1948 (Cyprinodontidae).''Environmental Biology of Fishes'' 61: 370. Retrieved September 29, 2011. The pupfish tolerates a wide range of water conditions. Its native habitat includes desert marshes with water temperatures up to 33 °C in the summer and layers of ice during the winter. The water in some areas has four times the salt content of the ocean, as well as low Oxygen saturation, oxygen. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catarina Pupfish
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 extinc ...

Cyprinodon Longidorsalis
''Cyprinodon longidorsalis'', the cachorrito de charco palmal or La Palma pupfish, is a species of fish in the family Cyprinodontidae. It was Endemism, endemic to the Ojo de Agua la Presa in southwestern Nuevo Leon state in Mexico, but became extinct in the wild in 1994 due to habitat loss (now survives only in captivity). The same freshwater spring system was the home of three other pupfish: ''Cyprinodon ceciliae'' (extinct), ''Cyprinodon inmemoriam'' (extinct) and ''Cyprinodon veronicae'' (extinct in the wild, survives in captivity). Although these were from the same spring system, each was restricted to its own individual spring pool. The Charco La Palma pool and its spring had a combined area of about and was no more than at the deepest point, making the range of the La Palma pupfish perhaps the smallest known for any vertebrate species. This tiny spring pond also was the home of a now-extinct, undescribed species of ''Cambarellus'' crayfish. The La Palma pupfish is a ray-fi ...

Titus Canyon Formation
The Titus Canyon Formation is an Late Eocene-aged geologic formation in Inyo County, California. It was deposited in an inland freshwater environment, and preserves fossil fish and mammal specimens. H. Donald Curry collected the type specimens of the three teleosts '' Fundulus curryi'', '' Fundulus euepis'', and '' Cyprinodon breviradius'' in the Titus Canyon Formation. Both of these genera are present in the Titus Canyon Formation sediments of Death Valley National Park. Footnotes References *Hunt, ReBecca K., Vincent L. Santucci and Jason Kenworthy. 2006.

Death Valley National Park
Death Valley National Park is a national park of the United States that straddles the California–Nevada border, east of the Sierra Nevada. The park boundaries include Death Valley, the northern section of Panamint Valley, the southern section of Eureka Valley and most of Saline Valley. The park occupies an interface zone between the arid Great Basin and Mojave deserts, protecting the northwest corner of the Mojave Desert and its diverse environment of salt-flats, sand dunes, badlands, valleys, canyons and mountains. Death Valley is the largest national park in the contiguous United States, as well as the hottest, driest and lowest of all the national parks in the United States. It contains Badwater Basin, the second-lowest point in the Western Hemisphere and lowest in North America at below sea level. More than 93% of the park is a designated wilderness area. The park is home to many species of plants and animals which have adapted to the harsh desert environmen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
