Why do Hatchetfish have light producing cells on their bellies?
Hatchetfish can regulate the intensity and color of light from these organs to match the light filtering down. This use of bioluminescent light is called “counterillumination,” a common adaptation in midwater fishes and cephalopods. Some midwater predators hunt by looking up for the silhouettes of animals.
