11. Pyura Chilensis
Location: South America (Chile and Peru)
The closest thing to getting blood from a stone! Lurking off the coast of Chile and Peru lives a sea creature that blends in so naturally with the rocks on which it lives. However, if you were to accidentally stand on this living rock it will burst to expose a mass of blood-red hermaphrodite creatures considered a delicacy in the nearby Central American countries. It is born a male before developing female organs which means it can breed with itself. Strange but true.
