Observations

The axolotl is a classic case of neoteny in that animals become sexually mature without undergoing the final metamorphosis to the land-borne adult. Although very rare in the wild, it is possible to induce metamorphosis in the lab using thyroxine injections but animals die shortly afterwards [0449]. Like other similar species, the axolotl is capable of limb regeneration, the study of which could be of benefit to regenerative medicine; they are also extremely resistant to cancer [0843]. Anecdotal evidence, which seems possible, suggests these animals may live up to 25 years.
