Ambystoma mexicanum, family Ambystomatidae
- ‘A number of salamanders, such as the North American ‘mudpuppy’ and the Mexican axolotl, develop legs but retain their larval gills and stay in the water throughout their lifetimes.’
- ‘Another family, the Ambystomatidae occurs in the New World from Canada to central Mexico and includes the tiger salamander and the axolotl.’
- ‘Urodele amphibians such as newts and axolotls show a remarkable capacity for regenerating body structures such as tails, limbs, jaws, and the lens of the eye.’
- ‘The exemplar of salamander paedomorphosis is the Mexican axolotl.’
