Bears are pretty much the puppy dogs of the wild. They are so cute that most people want to pet them... and that would be their first mistake. Polar bears are the largest carnivores on land; they eat ringed seals for breakfast but would settle for a young walrus or beluga whale.

Living in the Arctic Circle, they've certainly been known to kill humans who venture too close. It's starvation that makes them dangerous and a smack from one of their paws could rip your head clean off.
