We’re not talking about pit bulls dressed as pirates or dachshunds turned into hot dogs. In the wild, sometimes imitating something you’re not is the only way to survive.

While these ten creatues may deserve prizes for their diguises, they just scratch the surface of natural deception. Animals deceive to fool predators, threaten rivals and attract mates. Some scientists even propose that evolution has favored those who are so good at deception we can fool ourselves.
