About the Axolotl

The Peter Pan of amphibians - they retain their larval features throughout their lives (neoteny). They can regenerate almost any body part: limbs, heart, spinal cord, brain tissue, and even parts of their jaw. They can accept organ transplants from other axolotls without rejection. They are critically endangered in the wild - fewer than 100 remain in their single natural lake. They are one of the most studied animals in developmental biology. They can regenerate the same limb up to 5 times perfectly. They are bred in laboratories worldwide. Their genome is 10x the size of the human genome.
