Gecko gecko
When a leopard gecko feels threatened it loses its tail. The tail still moves because it has nerve endings in it, and will distract the enemy while the leopard gecko gets away. Eventually the leopard gecko will grow a new tail but it will not be as pretty as its old tail. It will grow back in a "light bulb" shape instead of sleek and straight.
WHY would you want to ! The gecko will ONLY eat when it's hungry ! If you tried feeding it everything it would get in a week, at one sitting - it would gorge itself.
There are two ways of defence that I know of, one is that they have the ability to drop their tail so that the tail distracts the predator, so hopefully the leopard gecko can scurry away. The second is biting.

They have the same name, but their color might be different. The spots and striped might be at their tail, the whole body, or the head. Their skin colors can be yellow, pinkish-orange, and that's all i know. :D
