Explore the incredible regenerative capacity of salamanders, and see how they’re able to regrow limbs, hearts, and even brain tissue.
--
For some animals, losing a limb is a decidedly permanent affair. But for salamanders, particularly axolotls, amputation is just a temporary affliction. Not only can they grow back entire limbs in as little as six weeks, they can also regenerate heart and even brain tissue. So, how does this astonishing adaptation work? Jessica Whited explores the incredible regenerative capacity of salamanders.
