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 ...

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 (S0103) (12598764423)
The sheepshead minnow or sheepshead pupfish (''Cyprinodon variegatus'') 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 to a length of up to though a more normal length is . 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 ...

Cyprinodon Radiosus
The Owens pupfish (''Cyprinodon radiosus'') is a rare species of fish in the family Cyprinodontidae, the pupfish. It is 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. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 Devil's Hole Desert Pupfish, native to 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 L. Hubbs, a prominent ichthyologist and one of the first peopl ...

Lake Chichancanab
Lake Chichancanab is a lake in Mexico located in the northwest of the state of Quintana Roo, in the municipality of José María Morelos. It is also known as Laguna Chichancanab, Laguna Chicnancanab and Laguna de Chichancanab. It has an approximate length of 30 kilometers from near the settlement of La Presumida to that of Kantemó, in the same municipality. It is the largest lake on the Yucatan Peninsula. The lake has a clay lake bed which seals the water off from the bedrock the water level is therefore determined by the balance between rainfall and evaporation. The lakes waters are saline, with high concentrations of dissolved minerals. When the area undergoes drought for a sufficiently long period then gypsum precipitates and concentrates in the mud on the lake bed. In the last five thousand years, this deposit of gypsum has occurred at just one period which coincided with the start of the decline of the classical Mayan civilisation. On 2 February 2004, Lake Chichancanab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinodon Longidorsalis
''Cyprinodon longidorsalis'', the cachorrito de charco palmal or La Palma pupfish, is a species of fish in the family Cyprinodontidae. It was 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-finned f ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribbean Islands
Almost all of the Caribbean islands are in the Caribbean Sea, with only a few in inland lakes. The largest island is Cuba. Other sizable islands include Hispaniola, Jamaica, Puerto Rico and Trinidad and Tobago. Some of the smaller islands are referred to as a ''rock'' or ''reef.'' ''Islands are listed in alphabetical order by country of ownership and/or those with full independence and autonomy. Islands with coordinates can be seen on the map linked to the right.'' Antigua and Barbuda There are 54 islands in Antigua and Barbuda. There are three main islands, the two populated islands (Antigua and Barbuda) and Redonda. There are 51 off-shore islands. The islands of the country of Antigua and Barbuda include: *Antigua, , * Northeast Marine Management Area ** Prickly Pear Island ** Great Bird Island ** Galley Island Major ** Galley Island Minor ** Jenny Island ** Exchange Island ** Rabbit Island ** Lobster Island ** Long Island ** Maiden Island ** Rat Island ** Little ...

US States
In the United States, a state is a constituent political entity, of which there are 50. Bound together in a political union, each state holds governmental jurisdiction over a separate and defined geographic territory where it shares its sovereignty with the federal government. Due to this shared sovereignty, Americans are citizens both of the federal republic and of the state in which they reside. State citizenship and residency are flexible, and no government approval is required to move between states, except for persons restricted by certain types of court orders (such as paroled convicts and children of divorced spouses who share child custody). State governments in the U.S. are allocated power by the people (of each respective state) through their individual state constitutions. All are grounded in republican principles (this being required by the federal constitution), and each provides for a government, consisting of three branches, each with separate and indepen ...
