The Flashflight Fish is one of the many fish that live in the Aphotic area of the ocean. There is no light there at all. They eat zooplankton that they find at night using their bioluminescent photophores. How do they live the such a dark place? Well Flashlightfish have a symbiotic relationship with glowing bacteria. The fluorescent bluish-green glow under a flashlightfish’s eye comes from billions of glowing bacteria that live under the fish’s skin in a bean-shaped photophore. The bacteria biochemcially produce this light. This built-in light helps the fish hunt, navigate, communicate and avoid predators. In return, the bacteria get a safe home, along with oxygen and nutrients they receive from the fish’s blood. Without a steady supply of oxygen, the bacteria wouldn’t be able to glow. Therefor, thats why they are needed in deep, deep, deep sea :))))))))))))))))) :))))))))))))))))))
