There is a real fish called a Barrel Eye that is probably the strangest creature in the ocean. They have a set of false eyes on the front of their transparent head and another set of actual eyes inside their head. They look through the clear dome of their head like a windshield. They have a tiny mouth and big flat fins that suggest that they are very precise in their movements and are are almost motionless as they feed on small prey. They were discovered in the 30s but no pictures were taken until 2004 because when you bring them up from the deep the change in pressure destroys them. It is amazing how nature works.
