Silly salamander
The axolotl is native to the freshwater channels and deep lakes of central Mexico.
Axolotis never actually undergo complete metamorphosis, so they remain in their larval state for their whole lives. They also have the ability to completely regenerate any limb.
This little water critter is part of an incredibly small surviving wild population. In 2006, the axolotl was placed on the list of critically endangered animals, according to the IUCN Red List of Threatened Species. It was presumed to be an extinct species until recent sightings in 2014 proved otherwise.
