It's a plane! It's a submarine! No, it's a barreleye fish.
This deep sea fish has freaky tubular eyes, embedded within a transparent head. Why? To see in the dark and battle stinging siphonophores for food. At least that's one theory.
I think it just wants to win the prize for best imitation of a submarine by a marine fish.
See the barreleye (aka spookfish) swim in this YouTube video sure to hit the top ten.
