No Teddy Bear
Polar bears are more likely than other bears to attack people. Surviving on a very meaty diet, they can weigh close to 2000 lbs. On the up side, unless you live in the Arctic, you’re unlikely to meet one.
Not So Gentle Giant
Gorillas are best treated with caution. Although generally gentle and leaf-munching, gorillas will attack and cause serious injury if they feel threatened. An adult male can reach up to a weight of 400 lbs!
