Стрекоза: Её личинка дышит задним проходом и им же стреляет

A dragonfly larva breathes through its anus, hunts through it, and moves through it—this isn't a metaphor or an exaggeration; these are three documented biological functions of a single orifice. And an adult dragonfly, with a brain the size of a grain of rice, hunts with 97% accuracy—better than a lion, better than a falcon, better than any other predator on the planet.
