Answer Details
The colour of the ventral (underside) surface of a fish is lighter than that of the dorsal (upper) surface mainly as an adaptation for camouflage. The lighter ventral coloration helps the fish blend in with the brighter water surface when viewed from below, making it less visible to predators. This is a common adaptation seen in many aquatic animals, including fish, to increase their chances of survival in their environment.
