Lizards can break off their tails when threatened by a predator; it then twitches causing a distraction and allowing the lizard to escape. The lizard can grow back its tail with a cartilage rod instead of bone. Much of a lizards excess fat is stored in the tail, so a lizard who loses its tail may not be able to reproduce that year.
