Laguna Catemaco
Laguna Catemaco () is a freshwater lake located at the center of the Sierra de Los Tuxtlas in south central Veracruz near the city of Catemaco, in east central Mexico. Name The word lagoon in English, and ''laguna'' in Spanish, generally describes a body of shallow brackish water, usually next to the sea. Thus despite the name, Laguna de Catemaco is not a lagoon, but an actual fresh water lake. Common usage in Mexico is ''Laguna de Catemaco'', though scientific articles tend to use the correct and less ambiguous name of ''Lake Catemaco'' in English, and ''Lago Catemaco'' in Spanish. Hydrology Laguna Catemaco was formed millennia ago, when lava flow from San Martin Tuxtla volcano blocked its current northern end, and stands now at 340 m (1,115 ft) above sea level. It is shallow, averaging 7.6 m (25 ft), with a maximum depth of 22 meters located in the channel between Isla Agaltepec and the city of Catemaco. The circulation pattern is clockwise.

Xiphophorus Hellerii
''Xiphophorus'' is a genus of euryhaline and freshwater fishes in the family Poeciliidae of order (biology), order Cyprinodontiformes, native to Mexico and northern Central America. ''Xiphophorus'' species can be divided into three groups based on their evolutionary relationships: platyfish (or platies), northern swordtails, and southern swordtails. Platyfish formerly were classified in another genus, ''Platypoecilus'', which is now obsolete. The type species is ''X. hellerii,'' the green swordtail. Like most other new world Poeciliids, platies and swordtails are Livebearers, live-bearers that use internal fertilization and give birth to live young instead of laying eggs like the bulk of the world's fishes. The name ''Xiphophorus'' derives from the Greek language, Greek words ξίφος (dagger) and φόρος (bearer), referring to the Fish fin#Reproduction, gonopodium on the males. All are relatively small fishes, which reach a maximum length of depending on the exact specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudoxiphophorus Bimaculatus
''Pseudoxiphophorus'' is a genus of fish from the family Poeciliidae. The species in the genus were formerly considered to be in the genus '' Heterandria'' but workers found that most of the species were not closely related to the type species of that genus, ''Heterandria formosa'', and seven species were transferred to the genus ''Pseudoxiphophorus''. They are found in Central America. Species The following seven species are classified as belonging to the genus: *'' Pseudoxiphophorus anzuetoi'' (Rosen Rosen is a surname of German and Ashkenazi Jewish origin, the name deriving from the German word for roses. Notable people with this surname include: Places *Rosen, Burgas Province, Bulgaria * Rosen, Dobrich Province, Bulgaria * Rosen, Minnesota, ... & Bailey 1979) *'' Pseudoxiphophorus bimaculatus'' (Heckel 1848)-(Twospot livebearer) *'' Pseudoxiphophorus cataractae'' (Rosen 1979) *'' Pseudoxiphophorus diremptus'' (Rosen 1979) *'' Pseudoxiphophorus jonesii'' ( Günther 1874) - ...

Xiphophorus Milleri
''Xiphophorus milleri'', the Catemaco platyfish, is a poeciliid fish endemic to Mexico's Lake Catemaco and its tributaries. As it has traits of both swordtails and platies, its discovery confirmed that these two groups should be consolidated into a single genus, ''Xiphophorus''. Taxonomy The species was named after American ichthyologist Robert Rush Miller, who collected it along with other ''Xiphophorus'' species. Its discovery enabled scientists to definitely conclude that platies and swordtails should be classified in the same genus, for it combines traits that were thought to separate platies from swordtails into different genera. Namely, ''X. milleri'' resembles the swordtails in body shape, pigmentation, and ecology, but shares the platies' secondary sexual characteristics, pigmentary polymorphism, and the absence of a sword. Description ''Xiphophorus milleri'' is a small to medium ''Xiphophorus'' species. Its body is slender. Nearly a half of specimens have melanophore ...

''Poeciliopsis'' is a genus of poeciliid fishes that primarily are native to Mexico and Central America. The only exceptions are ''P. turrubarensis'' where the range extends into Colombia, and ''P. occidentalis'' where the range extends into Arizona and New Mexico. Species There are currently 24 recognized species in this genus: * ''Poeciliopsis baenschi'' ( M. K. Meyer, Radda, Riehl & Feichtinger, 1986) (Golden livebearer) * ''Poeciliopsis balsas'' ( C. L. Hubbs, 1926) (Balsas livebearer) * '' Poeciliopsis catemaco'' ( R. R.

Poecilia Catemaconis
''Poecilia catemaconis'', the bicolor molly, is a livebearer fish from Mexico. ''Poecilia catemaconis'' belongs to the ''Poecilia sphenops'' species complex within the ''Mollienesia'' subgenus. It is most closely related to ''P. sphenops'', being derived from an Atlantic-slope population of that species. The specific epithet refers to Laguna Catemaco, which the species inhabits. The body is slender and elongated but the caudal fin, caudal and dorsal fins (especially in females) are short. Females grow to about 86 mm in standard length, while males attain 64 mm. When in breeding mood, the male's caudal and dorsal fins are half-bluish black, half-bright orange; similarly, the body is also partly golden. Horizontal rows of orange spots appear on the side of the body. The female's colors are duller. ''Poecilia catemaconis'' is known only from Laguna Catemaco, a freshwater lake in the eastern Mexican state of Veracruz, its tributaries and Rio Grande de Catemaco, its outlet. Young and ...

Heterandria Tuxtlaensis
''Heterandria'' is a genus of livebearing fishes within the family Poeciliidae. Most species occur in Guatemala and its surroundings, particularly Mexico, but the midget livebearer ('' H. formosa'') comes from the southeastern United States. Though many Poecilidae are familiar aquarium fishes, e.g. guppies, mollies, platys and swordtails, species within ''Heterandria'' are not commonly kept as pets. Somewhat more frequently found in aquaria is ''H. formosa'', perhaps because it is one of the smallest known fish species in the world; its diminutive males are probably the smallest fish easy to keep as a pet. Species in this genus resemble egg-laying Cyprinodontoidei such as Fundulidae (topminnows) at first glance, and are thus sometimes called "killifish" though this is technically erroneous.FishBase (2009)''Heterandria'' species Retrieved April 8, 2009.

Bramocharax Caballeroi
''Astyanax'' is a genus of freshwater fish in the family Acestrorhamphidae of the order Characiformes. Some of these fish, like many of their relatives, are kept as aquarium pets and known collectively as tetras. With around 150 described species and new ones being described yearly, this genus is among the largest of the entire order; ''Hyphessobrycon'' also has more than 145 species and which one is larger at any one time depends on whether more species have been recently described in one or the other. The blind and colorless cave tetra of Mexico is a famous member of the genus, but its taxonomic position is disputed: Some recognize it as part of the Mexican tetra (''A. mexicanus'') and this is supported by phylogenetic evidence, but others recognize the cave form as a separate species, '' A. jordani''. The type species is ''A. argentatus'', now regarded as a form of the Mexican tetra (''A. mexicanus''). The generic name comes from Astyanax, a character in Greek mythology, who w ...

Vieja Fenestrata
''Vieja'' is a genus of cichlid fish from Central America and Mexico. The majority of the species are freshwater fish found in stagnant or slow-moving waters of southern Mexico to El Salvador, but ''V. maculicauda'', which also occurs in brackish waters, ranges south to Panama. They are high-bodied cichlids that reach lengths of up to depending on the exact species. ''Vieja'' feed mostly on vegetable matter, but may also take small invertebrates. Taxonomy and species Historically, ''Vieja'' was included in '' Cichlasoma''. Once recognized as its own genus, it sometimes included most of the superficially similar, relatively large and high-bodied cichlids of Central America and southern Mexico, but several of these are now considered to belong to separate genera: '' Chuco'', '' Cincelichthys'', '' Isthmoheros'', '' Kihnichthys'', '' Maskaheros'' and '' Oscura'' (''Oscuro'' might still be better merged with ''Vieja'', but this remains unconfirmed).
