9. Bear (975 psi)
Bears are only No. 9 on this list, but they win the prize for most adorable. Not that there’s much cute about an angry, 800-pound grizzly, but between teddy bears, Winnie the Pooh and other pop-culture bear icons, humanity seems to have a long-standing wish to see these beasts as mere pot-bellied, sunny-dispositioned cuties that want nothing more out of life than honey and hugs. If you see one in the wild, though, don’t dare try rubbing its tummy. A bear’s 975-psi bite is enough to crush a bowling ball. And bear attacks aren’t particularly rare, either. If you plan on hiking or camping anywhere there are bears (i.e., basically any place for hiking or camping), you’d better know ahead of time what to do in case you encounter one. A bear is liable to attack you if it perceives you as any kind of a threat to its territory, food or family. Or it may just be hungry, and you look delicious. Don’t end up like these folks.
