When you think of a bat, the first images that spring to mind are probably dark caves, night skies, and blood-sucking monsters. But although they're an object of many fears and superstitions, bats have another secret side. Despite their wings, they are mammals like us and nurse their young with caring and affection. And though they look fierce, the society of bats is more peaceful than our own. So the next time you see a bat flitting overhead, think that it may be looking down with the same fascination and dread that you feel.
