The desert scorpion protects itself from predators by injecting them with a very painful, paralyzing venom through a needle like tip on its curved tail. But the southern grasshopper mouse (Onychomys torridus) has evolved a way to take that venom and turn it into an painkiller. The video below shows these two desert dwellers in a fight to the death. After you watch you may never think about mice the same way again.
