Ouroboros: The Tail-Eating Serpent
The ouroboros is an ancient symbol of a mythical serpent or dragon that bites its own tail. It has come to represent, rebirth, infinity and the continuous wheel of cycles. But it also turns out to be a clever way for some animals to defend themselves and can be seen in everything from storms on Saturn to nanotechnology.
