Summary
The barreleye fish (Macropinna microstoma) a deep-sea species that lives at a depth where there is no surface sunlight.

It's eyes are extremely light-sensitive and can rotate within a transparent, fluid-filled shield on its head. The fish's tubular eyes are capped by bright green lenses. The eyes point upward (as shown here) when the fish is looking for food overhead. They point forward when the fish is feeding. The two spots above the fish's mouth are olfactory organs called nares, which are analogous to human nostrils.
