Did you Know? Snakes have no eyelids.
Have you ever wondered or thought why snakes may make you feel uneasy? They don't even have eyelids! As a result, they cannot blink their eyes, and they sleep with their eyes wide open. To protect their eyes, they have a thin membrane linked to each of them instead of eyelids. The membrane is known as a brille, which translates as spectacles in German.
