Tasmanian Devils are the world’s largest carnivorous marsupials. These little creatures only weigh up to 26 pounds. Even though they appear cute and harmless, they’re vicious. They’re much more dangerous than you think, so it’s best you stay far away from these guys and don’t provoke them. Their name says it all, though, and they didn’t randomly earn the name “devil.” When they feel threatened, they become aggressive and display their sharp teeth for their predator. They’ll likely run in the opposite direction when they see a human, but if they feel threatened or want to defend their mate, they’ll attack with a strong bite (via Best Life Online).
