The axolotl (Ambystoma mexicanum) is a neotenic amphibian belonging to the family Ambystomatidae, native to the ancient lakes of the Valley of Mexico. Distinguished by its retention of larval traits throughout adulthood, the axolotl exhibits extraordinary regenerative abilities, capable of regenerating limbs, spinal cord, heart, and portions of the brain. Its unique developmental biology and endangered status make it a model organism in evolutionary, genetic, and regenerative studies.
