Marine Hatchetfish
Marine hatchetfish are creatures of the deep. They have rows of light-producing organs along their bellies which shine a pale blue — matching the light from above and making the hatchetfish invisible to predators below. This fish's name comes from its body shape, which resembles the head of a hatchet.
