The world's largest shark has thousands of teeth surrounding each of its eyes that act like armor.
Marine biologist from Japan discovered the dermal denticles lining the outer surface of the membrane and each has some 3,000 teeth around it.
Because whale sharks do not have eyelids, the rows of 'oak leaf-like' structures protect their eyes, which contradicts theories that this species does not rely heavily on its vision.
Along with the dermal denticles, researchers also demonstrated that the whale shark has the ability to retract about 50 percent of its eyeball into the socket.
