Changes

Several families of lizard can voluntarily discard the tail when seized by a predator. The discarded wriggling tail is thought to distract the attention of the predator, enabling the lizard to escape. The animal is able to grow a new tail, although the regenerated tail is never as long or well formed as the original.

Lizards that are capable of autotomy have a vertical fracture plane through the body and part of the neural arch of the tail vertebrae. This is a plate of cartilage or connective tissue that develops after ossification. Autotomy and regeneration occur in many iguanid species but not in many agamids, [[Monitor|monitors]] and [[Chameleon|chameleons]].
