Coloration: Silvery except for a black lateral band which expands near the caudal base and narrows on the caudal fin (Sublette et al. Oklahoma. O peixe-cego, também conhecido como tetra-cego (Astyanax fasciatus mexicanus) é um peixe de água doce para aquário em crescendo de popularidade. The eyeless, troglomorphic form is found only in Mexico but this species is in fact widely-distributed from the southern United States of Texas and New Mexico, through Mexico itself and into Guatemala. California Fish and Game 36:435-436. 413-456 in C. H. Hocutt and E. O. Wiley, editors. For queries involving fish, please contact Matthew Neilson. Cave fish and surface fish are able to produce fertile offspring. Miller, R. J., and H. W. Robison. The Mexican tetra (Astyanax fasciatus) consists of an eyed epigean form (surface fish, Astyanax fasciatus fasciatus) and blind hypogean forms (cavefish, including Astyanax fasciatus mexicanus) . [19] Active research focuses on the mechanisms driving the evolution of regressive traits, such as the loss of eyes, in A. mexicanus. [3][6], The Mexican tetra has been treated as a subspecies of A. fasciatus, but this is not widely accepted. The zoogeography of Arizona Fish and Game Department. A field guide to freshwater fishes of States with nonindigenous occurrences, the earliest and latest observations in each state, and the tally and names of HUCs with observations†. North Carolina State Museum of Natural History, Raleigh, NC. et al. [2020]. The blind cave tetra is a hardy species. Zoogeography of Le tétra aveugle Astyanax mexicanus est un poisson, parfois cavernicole pour le tétra mexicain. But evolution is a non-directional process, and while increased complexity is a common effect, there is no reason why evolution cannot tend towards simplicity if that makes an organism better suited to its environment. Le tétra aveugle, tétra cavernicole ou tétra mexicain (Astyanax mexicanus) est une espèce de poissons d'eau douce de la famille des Characidés originaire de l'Amérique centrale. 1980 et seq. [6], A. mexicanus is a peaceful species that spends most of its time in midlevel water above the rocky and sandy bottoms of pools and backwaters of creeks and rivers of its native environment. Minckley, W. L. 1973. 1981. [26] In this context, the positive genetic benefits have to be considered, i.e., what advantages are obtained by cave-dwelling tetras by losing their eyes? Sublette, taken in recent years and is now considered extirpated (Cashner and ", "Sensory Adaptations of Fishes to Subterranean Environments", "To See or Not to See: Evolution of Eye Degeneration in Mexican Blind Cavefish", "Genes, modules and the evolution of cave fish", "Regressive Evolution in Astyanax Cavefish", "Cryptic variation in morphological evolution: HSP90 as a capacitor for loss of eyes in cavefish", https://en.wikipedia.org/w/index.php?title=Mexican_tetra&oldid=992861076, Articles with unsourced statements from April 2018, Articles with unsourced statements from January 2014, Creative Commons Attribution-ShareAlike License, Mexican tetra, normal form (above) and blind cave form (below).

Members of several unrelated families have become blind cavefish. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. In contrast to regressive traits, the purpose or benefit of constructive traits is generally accepted. They prefer subdued lighting with a rocky substrate, like gravel, mimicking their natural environment. Guide to the fishes of New Mexico. Accessed [12/9/2020]. Follett, and L. J. Dempster.

E., and C. D. Riggs. Found from Mexico to Southern Brazil, for decades this species has been popular in zoos and private aviaries where they have been bred for more than 60 years. R. R. 1952. The teleost Astyanax mexicanus consists of an eyed epigean form (surface fish) and at least 29 different populations of eyeless hypogean forms (cavefish). The lack of eyes disables the "body clock", which is controlled by periods of light and dark, conserving energy. J. E., M. D. Hatch, and M. Sublette. Es una especie introducida artificialmente en Filipinas. Not developing eyes allows the individual more energy for growth and reproduction. Froese, Rainer and Pauly, Daniel, eds. Astyanax fasciatus mexicanus (De Filippi, 1853) Taxonomic Serial No. However the species does use other methods to locate food and detect danger, which also consume energy that would be conserved if it had eyes or transparent eyelids. Lee, Pages The fishes of Ohio. Proceedings of the Oklahoma Academy of Science 33(1952):141. Min. [3][4] The type species of its genus, it is native to the Nearctic realm, originating in the lower Rio Grande and the Neueces and Pecos Rivers in Texas, as well as the central and eastern parts of Mexico. All or most introductions have probably resulted from bait bucket releases (e.g., Miller and Robison 1973). É um membro da família Characidae (que pode atingir os 12 cm de comprimento, embora valores à volta dos 9 cm sejam mais comuns) e tal como todos os outros membros da família, é um depositor de ovos. Albuquerque, NM. (1980 et seq.) Lee et al. The generic name comes from Astyanax , a character in Greek mythology , who was the son of Hector of Troy ; in homage to this, several specific epithets also refer to the Iliad . In the winter, some populations migrate to warmer waters. Easy. Since then, these have been selectively bred for their troglomorphic traits. Astyanax fasciatus mexicanus Description: The body of the Blind cavefish is typical of the tetra (one of several species of small freshwater fish in the family Characidae ) – elongated and compressed laterally. Trautman, M. B. [16] Studies suggest at least two distinct genetic lineages occur among the blind populations, and the current distribution of populations arose by at least five independent invasions. Gainesville, Florida. Identification: Although previously considered a subspecies of Astyanax fasciatus (Lee et al. Houghton Mifflin Company, Boston, MA. fishes of southern California. Systematics, historical ecology, and North [5] The most divergent cave population is the one in Los Sabinos. Page, The Mexican cave fish is also referred to as the blind cave fish, blind cave characin, and blind cave tetra is a freshwater fish. Prefere águas duras e aquários especializados. Notes on fishes recently introduced into southern California. 1986. [citation needed] Experiments have shown that keeping these fish in bright aquarium set-ups has no effect on the development of the skin flap that forms over their eyes as they grow. The Peterson Field Guide Series, volume Evans, W. A., and P. A. Douglas. The Mexican tetra, Astyanax mexicanus, is a characin fish distributed throughout the rivers and caves of Northeastern Mexico .The river- or surface-dwelling form of Astyanax (surface fish) is typical of most other teleosts, including zebrafish. to the Pecos drainage downstream of Dexter (Sublette et al. 1957. [5] These were sent to an aquarium company in Texas, who soon started to distribute them to aquarists. Conner, J. V., and R. D. Suttkus.

Lambou, V. W. 1962. 68:1-7. Astyanax fasciatus Picture by Galtier Delbosc, M. Classification / Names Common names | Synonyms | Catalog of Fishes ( gen. , sp. ) l'Astyanax mexicanus est un tétra originaire des régions subtropicales et tempérées de l'Amérique du Nord, centrale et orientale.On le rencontre principalement au Mexique, au Texas et au Nouveau Mexique. Matthews 1988). [19][22] One of the most striking changes to evolve was the loss of eyes. freshwater fishes of the western Gulf Slope of North America. Modern genetics has made clear that the lack of use does not, in itself, necessitate a feature's disappearance. However sunlight does have minimal impact on the "body clock" in caves. it is predacious and highly aggressive, there is concern that this Ang Astyanax mexicanus sakop sa kahenera nga Astyanax, ug kabanay nga Characidae. Current alternative hypotheses suggest that adaptation to cave environments may have occurred either once or multiple times during the evolutionary history of this species. Nonindigenous Aquatic Species Database. [18] When the surface-dwelling ancestors of current cave populations entered the subterranean environment, the change in ecological conditions rendered their phenotype—which included many biological functions dependent on the presence of light—subject to natural selection and genetic drift. Cashner, [18] In addition to regressive traits, cave forms evolved "constructive traits". Further observation on Astyanax fasciatus This is the Mexican blind … [3], Growing to a maximum total length of 12 cm (4.7 in), the Mexican tetra is of typical characin shape, with unremarkable, drab coloration. species could impact native fishes by preying on their young (Miller El astyanax mexicanus habita en Norteamérica y Centroamérica. introduced. 1991. It is being provided to meet the need for timely best science. [7], The eyed and eyeless forms of A. mexicanus, being members of the same species, are closely related and can interbreed[18] making this species an excellent model organism for examining convergent and parallel evolution, regressive evolution in cave animals, and the genetic basis of regressive traits. 1958. 1978. mexicanus). Tank Size . Hubbs, C., T. Lucier, G. The absence of data does not equate to lack of effects. Astyanax mexicanus é unha especie de peixes da familia Characidae da orde dos Characiformes.. Esta especie foi ás veces tratada como unha subespecie de A. fasciatus, pero isto non está amplamente aceptado. This is referred to as a "regressive trait" because the surface fish that originally colonized caves possessed eyes. [5][20], Another cave-adapted population of Astyanax, varying from blind and depigmented to individuals showing intermediate features, is known from the Granadas Cave, part of the Balsas River drainage in Guerrero, southern Mexico, but it is a part of A. aeneus (itself sometimes included in A. North American freshwater fishes. The species belongs to the family Characidae of the order Characiformes. Possible explanations include: Another likely explanation for the loss of its eyes is that of selective neutrality and genetic drift; in the dark environment of the cave, the eyes are neither advantageous nor disadvantageous and thus any genetic factors that might impair the eyes (or their development) can take hold with no consequence on the individual or species. Astyanax fasciatus mexicanus. This is the only characid species native to the United States. † Populations may not be currently present. Mayden, [13] Blindness in A. mexicanus induces a disruption of early neuromast patterning, which further causes asymmetries in cranial bone structure. The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range.

(1990) and Page and Burr (1991) gave distinguishing characteristics. 6.8 - 7.3 Temp. 2005). 1950. [5][17][21], The surface and cave forms of the Mexican tetra have proven powerful subjects for scientists studying evolution. 7.6-8.9cm (3-3.5 ") sg. [5][7][8][9][10][11], A. mexicanus is famous for its blind cave form, which is known by such names as blind cave tetra, blind tetra (leading to easy confusion with the Brazilian Stygichthys typhlops), blind cave characin and blind cavefish. ; Page and Burr 1991). The Mexican tetra (Astyanax mexicanus), also known as the blind cave fish, blind cave characin, and blind cave tetra, is a freshwater fish of the family Characidae of the order Characiformes.

Recent studies have produced evidence that the mechanism may be direct selection,[23] or indirect selection through antagonistic pleiotropy,[24] rather than genetic drift and neutral mutation, the traditionally favored hypothesis for regressive evolution. 1992. the species is classified as "state endangered" by New Mexico (Sublette constituted part of the species' natural or historical distribution. [5] Other blind populations were initially also recognized as separate species, including antrobius described in 1946 from the Pachón Cave and hubbsi described in 1947 from the Los Sabinos Cave (both subsequently merged into jordani/mexicanus).

Description de Astyanax mexicanus (Tétra aveugle, Tétra cavernicole):. Surface fish possess large eyes that include a retina which is thick, well-differentiated, and clearly laminated. SF have complex social interactions. The fishes of Oklahoma. [5] Their lack of sight does not hinder their ability to get food. Fishes of Arizona. California Academy Science Occasional Papers 133. [5], This fish, especially the blind variant, is reasonably popular among aquarists. 1980 et seq. It is unknown why this species did not develop transparent skin or eyelids instead, as some species of reptiles did. By the time that an animal had reached, after numberless generations, the deepest recesses, disuse will on this view have more or less perfectly obliterated its eyes, and natural selection will often have effected other changes, such as an increase in the length of antennae or palpi, as compensation for blindness. Academy of Science 92(3):101-167. These two morphs differ by numerous traits, including behaviors. lower Rio Grande, lower Pecos, and Nueces rivers in Texas (Lee et al. One argument claims this is an instance of "devolution"—showing an evolutionary trend of decreasing complexity. Depending on the exact population, cave forms can have degenerated sight or have total loss of sight and even their eyes. 1973. Reported from Arizona, California, and Louisiana. P. Garrett, R. J.

Media in category "Astyanax mexicanus" The following 23 files are in this category, out of 23 total. 2005). There remains less chance of accidental damage and infection, since the previously useless and exposed organ is sealed with a flap of protective skin. Its natural diet consists of crustaceans, insects, and annelids, although in captivity it is omnivorous. We highly recommend reviewing metadata files prior to interpreting these data. [3] Additionally, the blind cave form is sometimes recognized as a separate species, A. jordani, but this directly contradicts phylogenetic evidence.

Atlas of North American freshwater Citation information: U.S. Geological Survey. [22], The blind form of the Mexican tetra is different from the surface-dwelling form in a number of ways, including having unpigmented skin, having a better olfactory sense by having taste buds all over its head, and by being able to store four times more energy as fat, allowing it to deal with irregular food supplies more effectively. 1992).

Bulletin of the Southern California 51 pp. [3] Its blind cave form, however, is notable for having no eyes or pigment; it has a pinkish-white color to its body (resembling an albino). [14] Scientists suggest that gene cystathionine beta synthase-a mutation restricts blood flow to cavefish eyes during a critical stage of growth so the eyes are covered by skin. Nevada, to Yuma, Arizona, with a key for identification. Riggs, C. D. 1954. Sims Printing Company, Inc., Phoenix, AZ.

Because there is no selection pressure for sight in this environment, any number of genetic abnormalities that give rise to the damage or loss of eyes could proliferate among the population with no effect on the fitness of the population. North America north of Mexico. and R. N. Fisher. Established in Texas (outside native range). Originalmente procede de las cuencas del río de Nuevo México y Texas. The species Astyanax mexicanus comprises both surface fishes (SF) that inhabit rivers and cave-adapted fishes (CF). Koster, W. J. Formerly found in the Rio The Mexican tetra, or Mexican cave fish, scientific name Astyanax mexicanus, is a fish having many names. They become semi-aggressive as they age, and are by nature schooling fish.

[19] This, combined with the ease of maintaining the species in captivity, has made it the most studied cavefish and likely also the most studied cave organism overall. (1991) provided distribution maps; these authors considered Mexican [16], The blind and colorless cave form of A. mexicanus is sometimes recognized as a separate species, A. jordani, but this leaves the remaining A. mexicanus as a paraphyletic species and A. jordani as polyphyletic. Cette espèce préfère les lagons à fond sableux ou rocheux, mais elle fréquente une grande diversité d'habitats, y compris les torrents rapides.
