When seen from below by a predator, the animal's light helps to match its brightness and colour to the sea surface above. Counter-illumination is a method of active camouflage seen in marine animals such as firefly squid and midshipman fish, and in military prototypes, producing light to match their backgrounds. Marine animals of the mesopelagic (mid-water) zone tend to appear dark against the bright water surface when seen from below.
