Although a lot of us really like animals, it often doesn't take too long in the process of learning about them for us to discover something that shatters our illusions about the cuter ones.
A lot of our favorite animals' dark sides tend to come out when they're mating, as you'll learn if you're unfortunate enough to hear how ducks, otters, and dolphins do it. Ducks are my favorite animals, so I assure you I'm in the same boat, too.
But some animals can find a way to disturb us just by hanging around on their own, as some Twitter users discovered when they saw bizarre photos of pelicans trying to relax.
