What are the common characteristics and functions of a dropped tail in various animal species?

A dropped tail is a common defense mechanism in many animal species. When threatened, some animals can detach their tails to distract predators and escape. The detached tail may continue to move, drawing the predator's attention away from the animal itself. This behavior is known as autotomy. The tail typically contains muscles that allow it to twitch and move even after being detached. Some animals, such as lizards and certain insects, can regenerate their tails after they have been dropped. Overall, a dropped tail serves as a survival strategy for many animals in the wild.
