The axolotl (/ ˈ æ k s ə l ɒ t əl / ⓘ; from Classical Nahuatl: āxōlōtl [aːˈʃoːloːtɬ] ⓘ) (Ambystoma mexicanum) [3] is a paedomorphic salamander closely related to the tiger salamander. [3] [4] [5] It is unusual among amphibians in that it reaches adulthood without undergoing metamorphosis. Instead of taking to the land, adults ...
The mole salamanders (genus Ambystoma) are a group of advanced salamanders endemic to North America. The group has become famous due to the study of the axolotl (A. mexicanum) in research on paedomorphosis, and the tiger salamander (A. tigrinum, A. mavortium) which is often sold as a pet, and is the official amphibian of four US states.
The genus Rhyacotriton was formerly included in this family, but is now usually placed into its own family Rhyacotritonidae.In 2006, a large study of amphibian systematics (Frost et al., Bulletin of the American Museum of Natural History, 297 (2006) placed Dicamptodon back within Ambystomatidae, based on cladistic analysis.
As hybrids age, they develop a phenotype that is a combination of achoques and axolotls. Hybrids retain the webbed feet but lack the dorsal fimbriae of achoques. Offspring involving Ambystoma tigrinum or A. tigrinum-A. mexicanum hybrids and Ambystoma dumerilii results in few viable offspring that are prone to congenital abnormalities.

Axolotl (Ambystoma mexicanum) salamander: Nahuatl: From āxōlōtl, after the god Xolotl ("two stalks"), who transformed into the animal. The specific name derives from Mexico, ultimately from Mēxihco (with many possible etymologies) [38] [39] Ayahuasca (Banisteriopsis caapi) liana: Quechua
The blunt-headed salamander (Ambystoma amblycephalum) is a mole salamander endemic to Mexico. It is only known from the vicinity of its type locality, near Morelia, in Michoacán state in Southwestern Mexico. [2] It inhabits a landscape consisting of a mosaic of natural grasslands and pine-oak forests at elevations of about 2,000 m (6,600 ft) asl.
The lake is located within the Mesa Central portion of Mexico, an area home to many neotenic Ambystoma species. It is temperate, with low salinity, and has a single stream originating from it. Ambystoma andersoni is listed as critically endangered on the IUCN Red List. map of where Anderson's salamander occurs
