countershading

n. a form of camouflage that involves using differential light and dark areas on the body to minimize the ability of predators to detect the organism. For example, fish often have dark-colored backs and light-colored bellies. A predator from below has difficulty discriminating the fish from the sky above, and a predator from above has difficulty discriminating the fish from the dark substrate below.
