Barreleye Fish Seen In Wild

I sometimes wonder wither I should have gone into Zoology. So the National Geographic has the First Photos of the Barreleye fish in the wild. This is significant because since the fish was first discovered in 1939 by Chapman, only corpses had been studied, but in the wild it is clear that it is a fish with eyes inside a transparent head. The new discovery here is that it can rotate it's eyes to look up when possibly searching for food or forwards when it eats. What it eats however is still kind of a mystery.
