Axolotl (Mexican salamander)

Ambystoma mexicanum

It can reproduce in larva form

Originally from mountain lakes in Mexico, the albino Mexican walking fish is an amphibian which lives in water at temperatures of 20°C maximum. It is white with red external gills. This animal has often been studied by scientists because it can live its whole life and reproduce in larva form (neoteny). It can also regenerate damaged or destroyed organs.
