Barreleye Fish

Facts

• Order: Argentiniformes
• Family: Barreleye fish
• Habitat: Deep sea (1,312 to 8,202 feet; 400 to 2,500 meters)

Transparent Part: Head

The barreleye fish has a head that’s see-through at the top. Their eyes are very flexible and can be pointed straight up. Perfect for using the smallest ray of light. And this lets them see predators circling above. The see-through head isn’t for camouflage, but for making sure the spook fish can get of trouble in time.
