Detailed explanation-1: -Countershading is a form of camouflage in which the top of an animal’s body is darker in color, while its underside is lighter.

Detailed explanation-2: -Countershading, or Thayer’s law, is a method of camouflage in which an animal’s coloration is darker on the top or upper side and lighter on the underside of the body. This pattern is found in many species of mammals, reptiles, birds, fish, and insects, both in predators and in prey.

Detailed explanation-3: -Countershading is a possible defence. If an animal is darker on top and lighter below, this can offset shading from light and make it harder for predators to detect them.

Detailed explanation-4: -backswimmers. …is a good example of countershading, as its light-coloured back, seen from below, blends into the water surface and sky. The rest of the body is darker and, when seen from above, blends with the bottom of the body of water in which it lives.
