"February 23, 2009--With a head like a fighter-plane cockpit, a Pacific barreleye fish shows off its highly sensitive, barrel-like eyes--topped by green, orblike lenses--in a picture released today but taken in 2004...."

That's one odd fish. The video's narration explains that the green shapes in its head are pupils of its eyes. This is the first barreleye, or Macropinna microstoma, that's been seen alive, and all in one piece.
