Ambystoma mexicanum
Fascinating amphibian that reaches maturity in larval form. Charming face and external gills are popular. Amazing regeneration ability.
The axolotl is a species of paedomorphic mole salamander. They mature into the terrestrial adult form without undergoing metamorphosis; the adults remain fully aquatic with obvious external gills. This trait, although somewhat unusual among the majority of amphibians, is not unique. Axolotls may be difficult to distinguish from the larval stage of other neotenic adult mole salamanders, such as mudpuppies or the occasionally paedomorphic tiger salamander.
