Asia is the largest and most populated continent on the planet. Here people compete for space with some of the most impressive animals in the world. Creatures that have ingenious adaptations to hunt and defend. Large and powerful predators stalk the snowy landscape in Siberia, and patrol the tropical waters of the Pacific. Ancient, armored creatures rule Asia's grasslands and wetlands. Deadly snakes strike from below, while cunning monkeys attack from above. And perhaps most impressive is the massive polar bear, the largest land based carnivore. They are remarkable animals, armed with massive jaws, venomous bites and impressive strength. Take a journey into their domain for a close-up look at their lethal abilities: how they hunt, kill, and defend. And see what happens if we get in their way.
