axolotl
Gilled adult amphibian
An axolotl is a salamander native to Mexico that remains in its aquatic larval form throughout life, retaining external gills and a finned tail.
Unlike most amphibians, it never undergoes metamorphosis to become land-dwelling.
Axolotls are studied for their remarkable ability to regenerate limbs and organs, and are kept as aquarium pets.
