Cyprinodon Labiosus
The thicklip pupfish (''Cyprinodon labiosus''), known in Spanish as ''Cachorrito cangrejero'', is a species of fish in the family Cyprinodontidae. The thicklip pupfish is endemic to Laguna Chichancanab in Quintana Roo, Mexico. In almost all places, different ''Cyprinodon'' species do not overlap in their range, but there are two notable exceptions and one of these is Lake Chichancanab, which is inhabited by ''C. labiosus'', '' C. beltrani'', ''C. esconditus'', '' C. maya'', '' C. simus'', ''C. suavium'' and '' C. verecundus'' (the other place where several ''Cyprinodon'' species live together are lakes in San Salvador Island, the Bahamas). Among the endemic ''Cyprinodon'' species in Lake Chichancanab, only ''C. beltrani'' and ''C. labiosus'' still occur in some numbers in their habitat, while the remaining are virtually—if not fully— extinct in the wild (at least some of these still survive in captivity). They usually live in a tropical climate with temperatures ranging from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyprinodon Maya
The Maya pupfish (''Cyprinodon maya''), known in Spanish as ''cachorrito gigante'', is a highly threatened species of fish in the family Cyprinodontidae. It is endemic to Lake Chichancanab in Quintana Roo, Mexico. In almost all places, different ''Cyprinodon'' species do not overlap in their range, but there are two notable exceptions and one of these is Lake Chichancanab, which is inhabited by ''C. maya'', '' C. beltrani'', '' C. esconditus'', '' C. labiosus'', '' C. simus'', '' C. suavium'' and '' C. verecundus'' (the other place where several ''Cyprinodon'' species live together are lakes in San Salvador Island, the Bahamas). Living together, the ''Cyprinodon'' species in Lake Chichancanab have diverged into different niches. Pupfish typically feed on algae and detritus. In Lake Chichancanab, however, ''C. maya'' has become not only the largest species in the genus ''Cyprinodon'', up to long, but also the only that catches and eats whole fish ('' C. desquamator'' of San Salva ...

Taxa Named By Robert Rush Miller
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 intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Fish
As of September 2016, the International Union for Conservation of Nature (IUCN) lists 643 endangered fish species. 4.2% of all evaluated fish species are listed as endangered. The IUCN also lists ten fish subspecies as endangered. Of the subpopulations of fishes evaluated by the IUCN, 24 species subpopulations have been assessed as endangered. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by ''critically endangered'' species, which meet the quantitative criteria for endangered species. Critically endangered fishes are listed separately. There are 1098 fish species which are endangered or critically endangered. Additionally 3191 fish species (21% of those evaluated) are listed as ''data deficient'', meaning there is insufficient information for a full assessment of conservation status. As these species typically have smal ... [...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] |
Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct In The Wild
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss. Examples Examples of species and subspecies that are extinct in the wild include: *Alagoas curassow (last unconfirmed sighting reported in the late 1980s, listed extinct in the wild since 1994) *Beloribitsa * Cachorrito de charco palmal (last seen in 1994, listed extinct in the wild since 1996) * Christmas Island blue-tailed skink (listed extinct in the wild since 2014) *Dabry's sturgeon (listed extinct in the wild since 2022) * Escarpment cycad (listed extinct in the wild since 2006) *Franklinia (last seen in 1803, listed extinct in the wild since 1998) *Golden skiffia (listed extinct in the wild since 1996) *Guam kingfisher (listed extinct in the wild since 1986) *Hawaiian crow or ʻalalā (last seen in 2002, li ...

San Salvador Island
San Salvador Island (known as Watling's Island from the 1680s until 1925) is an island and district of The Bahamas. It is widely believed that during Christopher Columbus's first expedition to the New World, this island was the first land he sighted and visited on 12 October 1492. He named it ''San Salvador'' after Christ the Saviour. Columbus's records indicate that the native Lucayan inhabitants of the territory, who called their island Guanahaní, were "sweet and gentle". History When he made landfall on the small island of San Salvador in October 1492, Columbus thought he had reached the East Indies, which was precisely his quest: to find an all-water route to the Orient so that European traders of precious spices could maximise their profits by cutting out Muslim middlemen. Additionally and more specifically, he was working on behalf of the Spanish to surpass the Portuguese, who had established trade routes around the Horn of Africa, a trans-Atlantic route being presume ...

Cyprinodon Verecundus
The largefin pupfish (''Cyprinodon verecundus''), also known as cachorrito de dorsal larga, is a small species of pupfish in the family Cyprinodontidae. It is endemic to Lake Chichancanab in Quintana Roo, Mexico. In almost all places, different ''Cyprinodon'' species do not overlap in their range, but there are two notable exceptions and one of these is Lake Chichancanab, which is inhabited by ''C. verecundus'', '' C. beltrani'', '' C. esconditus'', '' C. labiosus'', '' C. maya'', '' C. simus'' and '' C. suavium'' (the other place where several ''Cyprinodon'' species live together are lakes in San Salvador Island, the Bahamas). Living together, the ''Cyprinodon'' species in Lake Chichancanab have diverged into different niches. Pupfish typically feed on algae and detritus. In Lake Chichancanab, however, ''C. verecundus'' has become an amphipod- and bivalve-eater. The IUCN last reviewed ''C. verecundus'' in 2019 where they considered it vulnerable. Among the endemic ''Cyprinodon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinodon Simus
The boxer pupfish (''Cyprinodon simus'') is a small species of pupfish in the family Cyprinodontidae. It is endemic to Lake Chichancanab in Quintana Roo, Mexico. In almost all places, different ''Cyprinodon'' species do not overlap in their range, but there are two notable exceptions and one of these is Lake Chichancanab, which is inhabited by ''C. simus'', '' C. beltrani'', '' C. esconditus'', '' C. labiosus'', '' C. maya'', '' C. suavium'' and '' C. verecundus'' (the other place where several ''Cyprinodon'' species live together are lakes in San Salvador Island, the Bahamas). Living together, the ''Cyprinodon'' species in Lake Chichancanab have diverged into different niches. Pupfish typically feed on algae and detritus. In Lake Chichancanab, however, ''C. simus'' has become a zooplankton-feeder. It once occurred in large schools, but has declined drastically due primarily to introduced species (Nile tilapia and the tetra ''Astyanax fasciatus''). Among the endemic ''Cyprinodon ...
