Detailed explanation-1: -A LIZARD SEVERS its tail as a self-defence mechanism in order to distract its predator – this is known as autotomy (literally from the Greek ‘self’ and ‘sever’) or self-amputation. Lizards are born with a line of weakness in their tail, technically called a fracture plane.

Detailed explanation-2: -When a lizard detaches its tail, the tail whips around and wiggles on the ground. Nerves from the lizard’s body are still firing and communicating with each other. In fact, sometimes the tail will keep moving for upwards of a half hour. This distracts a predator and gives the lizard plenty of time to escape.

Detailed explanation-3: -Tail-shedding, known to scientists as caudal autotomy, is a common anti-predator defense among lizards. When attacked, many lizards jettison the wriggling appendage and flee. The predator often feasts on the tail while the lucky lizard scurries to safety. Later, the lizard simply grows a new tail.

Detailed explanation-4: -Under threat or attack, garden lizard loses a part of its tail which trembles and avert the attention of predators, so that the lizard escape later the tail regrown for lizard.
