Which animal can regenerate the most extensive range of body parts?

Regeneration is the ability of an organism to regrow lost body parts. While many animals can regenerate certain body parts like tails, limbs or fins, some animals are able to regenerate a much wider range of body parts.

The animal that can regenerate the most extensive range of body parts is the axolotl, a type of salamander native to Mexico. Axolotls can regenerate their limbs, spinal cord, heart, parts of their brain, and even their jaws. They can also regenerate damaged internal organs such as their kidneys and lungs.

Scientists are studying the axolotl's remarkable ability to regenerate body parts in the hope of being able to apply the same principles to humans, allowing for the regrowth of limbs and organs.
