At 60 mph, the cheetah is fast, but watch these other speedy creatures fly! The basilisk lizard runs so fast that it can walk on water and the ostrich is just about the fastest animal on two legs. Meet the most extreme of the speedsters.

Some animals are extreme in the amount of young they can produce, while others create some of the biggest babies on earth! Join Animal Planet for a countdown to the most extreme births from the Tasmanian Devil to the Kiwi.

Nobody likes a cheater, but in the natural world it's the cheaters that get ahead of the game. Animals use camouflage and false signals to lure prey close so they can move in for the kill.

Could you hang with the world's best survivors? From cockroaches withstanding 200 times more radiation than humans, to emperor penguins standing still in icy winds for 65 days, animals awe us with their amazing survival abilities.

Instead of a traditional narrative plot, the episode structured its "plot" as a countdown that examined why humans possess deep-seated, evolutionary phobias of certain creatures.

Prepare for action, because we're going head to head with the best warriors in the natural world. From bull elephant seals and powerful polar bears, to bugs with a black-belt, these contenders are not to be messed with.
