Possessing incredible strength and speed, the puma is one of the most formidable predators on the planet. But it's the puma's skill at jumping that gives it the No. 6 spot on our countdown. Also known as a mountain lion, cougar or panther, this animal has muscular hind legs and large paws designed for powerful leaping. From a standing position, the puma has been known to jump 15 feet vertically. With a running start, the animal can easily clear 40 feet horizontally. Pumas use this incredible skill to hunt, quietly sneaking up on prey until they are within pouncing distance and then delivering a swift and fatal bite to the neck.
