New page

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.

−	If the tail is completely discarded, it '''cannot be reattached''' due to the disruption to the blood supply of the tail. The animal is able to '''grow a new tail''' - growth normally begins after approximately one month, and is complete after approximately one to two years. The regenerated tail is '''never as long or well formed''' as the original and may have a slightly different scale colour and pattern.
