    Glow in the dark sharks that live in the deep ocean have evolved to have special eyes that help them see in the low light conditions.

    Researchers have discovered the science behind the bioluminescent shark’s eyes, by comparing them with the eyes of other sharks.

    Their eyes allow them to see the points of light that reach the depths of the ocean, and recognize other bioluminescent fish.

    One important discovery made by the study found that there is a space between the lens and iris of the shark’s eye that lets extra light into the retina.

    According to study researcher Julien Claes, a biologist at the at the Catholic University of Louvain in Belgium: "There are about 50 different shark species that are able to produce light — about 10 percent of all currently known sharks."

    They live at depths of between 650 to 33 hundred feet below the surface of the ocean, in an area called the mesopelagic twilight zone.

    Being able to produce light helps to keep them hidden from predators by camouflaging against the sunlight above.

    It also helps the sharks identify potential mates and hunting partners that belong to the same species.
