Lethal weapons are a must in the natural world: animals kill to survive. Nat Geo WILD tracks down the elite warriors that have upgraded their artilleries - forget teeth or claws, this is sophisticated killing technology. Slow-motion cameras capture the force as its tongue accelerates to more than 13 miles per hour in only 20 milliseconds, while the tip forms a suction seal around its prey. Meet the aye-aye, the world's largest nocturnal primate, known for its extra-long finger used to killl.
