Most of the time, a lizard loses its tail as a way of helping it to escape from a predator. If an animal grabs a lizard by its tail to capture it, the lizard can just separate from his or her tail and run away! When this happens, certain kinds of lizards can grow back their tails over a period of time. This special ability is known as âautotomy.â Usually the new tail isnât quite the same as the old one, but it can still help the lizard with movement and balance, like the old tail.
