As their name suggests, barreleye fish have really weird tubular eyes that they can rotate to gaze upward through their transparent foreheads. Although they appear green, the lenses are actually tinted with a yellow pigment that helps these bizarre fish distinguish between sunlight and bioluminescence.

Link to some actual footage of one.
