No Teddy Bear
Known for their attacking ability, the Polar Bears survive on meat and weigh almost 2000 lbs. Forget all that approach-ability, keep your distance. I mean, you can’t meet one really, unless you’re in the Arctic. Phew.
Not So Gentle Giant
Treat gorillas, found in Central Africa, with care as they tend to attack if they feel threatened by any of your activity. Although they are gentle enough, the injury caused is very serious due to their powerful hands and sharp teeth. 400 pounds is no laughing matter.
