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 ...

Undescribed Species
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a '' nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp"., but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Salvador Contreras-Balderas
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freshwater Fish Of Mexico
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] |
Fish Described In 1993
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

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 ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Cambarellus
''Cambarellus'' is a genus of small freshwater crayfish in the family Cambaridae. The 19 species are found in Mexico (subgenus ''Cambarellus'') and the Gulf States of the United States (subgenus ''Pandicambarus''). Among the Mexican species, ''C. areolatus'', ''C. patzcuarensis'', and ''C. prolixus'' are considered seriously threatened by the IUCN, and ''C. alvarezi'' is already extinct. ''C. chihuahuae'' was also believed to be extinct until rediscovered in 2012. ''C. alvarezi'' and four undescribed, extinct ''Cambarellus'' species were restricted to desert spring systems in southwestern Nuevo León; each one shared its habitat with a ''Cyprinodon'' pupfish (these are also fully extinct or extinct in the wild). An orange form of ''C. patzcuarensis'' is regularly seen in the freshwater aquarium trade. Species The genus contains the following species: ;Subgenus ''Cambarellus (Cambarellus)'' *†''Cambarellus alvarezi'' (Villalobos, 1952)Villalobos, A. (1952). Estudios de los ...

Cyprinodon Veronicae
The Charco Palma pupfish (''Cyprinodon veronicae'') is a species of small fish in the family Cyprinodontidae. It is endemic to the Ojo de Agua la Presa in southwestern Nuevo Leon state in Mexico. Although listed as critically endangered by the IUCN in 1996, the species is now extinct in the wild (only survives in captivity). The same freshwater spring system was the home of three other pupfish: ''Cyprinodon ceciliae'' (extinct), ''Cyprinodon inmemoriam'' (extinct) and ''Cyprinodon longidorsalis'' (extinct in the wild, survives in captivity). Although these were from the same spring system, each was restricted to its own individual spring and associated waters. The exact spring and associated waters inhabited by the Charco Palma pupfish were also the home of three now-extinct invertebrates: An undescribed species of ''Cambarellus'' crayfish, the valvatid freshwater snail ''Valvata beltrani'' and an undescribed species of valvatid freshwater snail.
