Meet the creature that can pretty much regenerate everything in it's body.

In the wild it remains in the larva state and will never undergoes Metamorphosis into an adult salamander. According to International Union for the Conservation of Nature and Natural Resources [IUCN] these species are critically endangered.The key thing for it's regenerative ability is it's immune system. Immune cells called Macrophages are critical during the early stage of regenerating it's lost limbs. Taking out of these cells,permanently stopped it's regeneration ability.In fact,
Macrophages
Scientists done an experiment by injecting a drug which takes off the Macrophages completely, they observed no regrowth in it's body.But in some Axolotls in which the Macrophages are partially depleted, the regrowth is seen but at a slower pace Axolotl isn't the the only one which has the ability to regenerate. Tadpoles are also known to regrow limbs Flatworms,Sea star are some examples. According to Edward Scott ,principal investigator for the GO grant and director of the McKnight Brain institute's program in stem cell Biology and Regenerative medicine."The Mexican salamander is the champion of vertebrate regeneration with the power to regenerate it's whole limbs and even parts of it's central nervous system
