18. Just like a normal lizard, geckos cut their tails off when they are attacked by the predator. It is a process called autotomy. They do this to confuse the predator. The tails jump, move here and there, and catches the attention of predator which buys gecko valuable time to escape from the predator. They can grow their tails back.
