Tadpoles, the initial form taken by young amphibians such as frogs and salamanders, have an extraordinary quality which sets them apart from mammals. They are able to regenerate their tails should they be eaten by a predator. If a tadpole loses its tail, it will grow a new one within a week! Imagine if a human can do that with an amputated limb. For several years, scientists have been studying the tadpole’s regenerative tail, trying to understand the process, eventually leading to treatments and therapies that might help humans to heal their wounds.
