Xenotoca
''Xenotoca'' is a genus of fish in the family Goodeidae from Mexico, where found in a wide range of habitats, from rivers and creeks to pools and lakes, in the Lerma– Grande de Santiago, Panuco, Cuitzeo and other basins of the Mesa Central. While no goodeid is a very common aquarium fish, the redtail splitfin (''X. eiseni''), is one of the most common aquarium goodeids. Its relatively bright colors offset its reputation for being aggressive towards tankmates, occasionally even killing them. Similarly to that species, two species described in 2016 have males with red-orange tails, but this feature is not shared by the remaining members of the genus. The ''Xenotoca'' species are small, reaching up to in standard length. Species There are currently five recognized species in this genus, but two possibly undescribed species, tentatively referred to as ''Xenotoca cf. melanosoma'' and ''Xenotoca cf. variata'', are known. Genetic work has shown that the genus, as currently defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Redtail Splitfin
The redtail splitfin or redtail goodeid (''Xenotoca eiseni'') is a species of goodeid fish from the family Goodeidae and subfamily Goodeinae. Like other members of Goodeinae, the redtail splitfin is native to Mexico and a livebearer. However, the goodeid mating system differs in several ways from the more common livebearing fish from the family Poeciliidae that includes guppies and swordtails. While no goodeid species is a very popular aquarium fish, the redtail splitfin is one of the most popular. Only the male has the red-orange tail for which it is named. Its specific name honours the collector of the type, Gustav Eisen (1847–1940) who was Curator of Marine Invertebrates at the California Academy of Sciences in San Francisco, California. Range and habitat The redtail splitfin comes from west-central Mexico in the Grande de Santiago River basin and waters near Compostela, Nayarit. It might also occur in the uppermost Ameca and Armería River basins, but the taxonom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goodeidae
Goodeidae is a family of teleost fish endemic to Mexico and some areas of the United States. Many species are known as splitfins. This family contains about 50 species within 18 genera. The family is named after ichthyologist George Brown Goode (1851-1896). Distribution The family is divided into two subfamilies, the Goodeinae and the Empetrichthyinae. The Goodeinae are endemic to shallow freshwater habitats in Mexico, particularly along the Mesa Central area (especially the Lerma River basin, smaller rivers directly south of it and inland to around the Valley of Mexico region), with some species found in brackish fringes at the Pacific coast, and north to central Durango, central Sinaloa and north San Luis Potosí. There are about 45 species of Goodeinae in 16 genera (some list 2 additional genera). The Empetrichthyinae are found in the southwestern Great Basin in Nevada, the United States, and contains 4 species in 2 genera. Physical information The name "splitfin" comes fr ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Freshwater Fish Genera
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Endemic Fish Of Mexico
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] |
