The Axolotl (Ambystoma mexicanum) is a fascinating freshwater amphibian native to the ancient lakes of Xochimilco near Mexico City. Often called the “Mexican Walking Fish”
(despite not being a fish), axolotls spend their entire lives underwater and retain their
feathery external gills into adulthood. Their unique appearance, gentle nature, and
incredible ability to regenerate body parts have made them one of the world's most
remarkable amphibians.
