The majority of adult axolotls will never fully mature into a typical adult salamander. However, the axolotl can undergo metamorphosis if it has to – for example if its habitat dries up.
Scientists are keen to study axolotls as they have the ability to regenerate limbs. If they have an accident and lose a leg, they are able to grow a new one in its place!
Axolotls have rudimentary teeth used for gripping but lack teeth designed for biting or tearing. This means that food has to be swallowed whole.
