Scientist had just recently discovered an aquatic specie in deep sea that has a transparent forehead within which one can see its glowing green eyes which is now called the “barreleye”

The barreleye fish is very rarely sighted. According to MBARI, despite 5,600 dives and more than 27,600 hours of video recordings done by the new state of the art remotely operated vehicles, the marine scientists could only encounter the fish 9 times.

The MBARI website records that this 150 millimeters long fish is found at the depth of 2,000–2,600 feet where the sunlight fails to penetrate. In 2009, the researchers found that barreleye fish “can rotate its eyes towards the front to see its food when eating”
