Animals with countershading have different colors on their backs and stomachs. Squirrels have gray or brown fur on top and white fur on their undersides. The darker top fur makes it harder for predators to see them when they are on the ground. When they are perched on a tree branch, the white fur on their bellies helps to blend them into the sky. Penguins also have counter shading.
Penguins spend a lot of time in the water.
The dark feathers on their backs help camouflage them from predators that are swimming above them. Their white stomach feathers hide them from predators swimming below them. . Mimicry is another type of deceptive coloration. It can protect the mimic from predators or hide the mimic from prey. If mimicry was a play, there would be three characters.
