Lizard Tail

Lizards Home > Library > Anatomy
 

Some lizard species can drop their tail. This action is called autotomy, and is one defensive technique that can help keep a lizard alive in the wild.

When lizards are caught by a predator, or feel threatened and drop their tail, it tends to distract their predators. This moment allows the lizards to escape to a safe hiding place. The tail has its own nervous system, and may also continue to move independently, further distracting the predator.

In most cases, the tail of the lizard may grow back to some degree. They do not develop new bones to replace the lost ones, but new cartilage is developed. You may also notice a slight difference in coloration or pattern of scales.
