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.
