Axolotl

The axolotl is an aquatic salamander native to Mexico, recognized by external gills, a broad head and a finned tail. It usually retains juvenile features into adulthood rather than undergoing the full change to a land-dwelling form. It feeds on small aquatic animals. Feathery gills assist breathing while the tail propels swimming. Its ability to regrow damaged body parts has made it important in scientific research. Captive color varieties differ from the darker, mottled appearance associated with wild animals.
