To Keep Predators Away, Snake Pretends Its Rear Is a Head

Scientists have discovered a clever way the yellow-lipped sea krait snakes deter predators: By making it look as though the venomous snake has two heads, according to a study published in the journal Marine Ecology. A biologist first noticed the snakes' tricky method while diving in Indonesia. Researcher Arne Rasmussen observed the animals foraging for food while simultaneously moving what appeared to be a bobbing head around--but that bobbing body part was really its tail.
