The Mystery of the Barreleye Fish

The Pacific barreleye fish, found deep in the Pacific Ocean, is known for its unique transparent head and tubular eyes. These adaptations help it survive in its dark habitat by allowing it to see prey above. The fish's eyes are green, possibly to filter sunlight and enhance bioluminescent prey visibility. Researchers discovered that the fish can rotate its eyes forward to aid in feeding. Despite its elusive nature, studies have revealed fascinating insights into its anatomy and behavior.
