As one of the strangest, cutest creatures on this list, it may come as a shock that they’re much more dangerous than you think. Their duck-like bills and webbed feet make them seem adorable and friendly. How could an animal with a beaver tail and webbed feet hurt you? They’re the only mammals to lay eggs, but also incredibly venomous. The male has a venomous spur on its hind foot that isn’t strong enough to kill a human, but powerful enough to cause a lot of pain. These are the best sort of animals to watch from afar and appreciate their cuteness from a good distance away (via Best Life Online).
