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 plateau tiger salamander or Mexican tiger salamander (Ambystoma velasci) is a species of mole salamander in the family Ambystomatidae. It is typically considered endemic to Mexico, [2] although its range might extend to the United States. [1] Its natural habitat is grassland, including sparse forest and semiarid grassland.
The California tiger salamander is a relatively large, secretive amphibian endemic to California. Adults can grow to a total length of about 7–8 inches. It has a stocky body and a broad, rounded snout. Adults are black with yellow or cream spots; larvae are greenish-grey in color.
These salamanders are mostly terrestrial and eat invertebrates, although some species are known to eat smaller salamanders. They can be found throughout the US and some areas of Canada in damp forests or plains. This family contains some of the largest terrestrial salamanders in the world, the tiger salamander and the coastal giant salamander ...
The axolotl has three pairs of external gills. This type of gill is most commonly observed on the aquatic larva of most species of salamanders , lungfish , and bichirs (which have only one large pair), and are retained by neotenic adult salamanders and some species of adult lungfish.
[9] [4] Morphologically, they are most similar to Anderson's salamander, with both species sharing a broad head and equal gill raker numbers. [14] Achoques are also compared to the axolotl and Taylor's salamander since all three species share a similar geographical location, taxonomic ranking, and have broadly similar morphological features.
