The animal kingdom can be harsh. What to do if you are a small animal trying to defend yourself or a predator who wants to stealthily stalk their prey? Evolution's answer—camouflage. While we often think of the chameleon as the perfect example of camouflage, in reality, things are much more complex.
Two types of camouflage exist, one that makes animals difficult to see—crypsis—and one that disguises them as something else—mimesis. Crypsis, the most common type of animal camouflage, is often achieved because the animal's colors resemble their environment. However, this is not the only way that animals can blend into the background.
Other forms of crypsis include animals that have patterns or markings that deliberately make it difficult to perceive the outlines of their bodies. Jaguars and the common frog are two examples of animals with this disruptive coloration. Other animals, such as butterflies and certain types of lizards, go to great lengths to eliminate their shadows, a technique that was employed by military camouflage during WWII.
Some camouflage animals will even reinforce their disguise by mimicking certain behaviors. For instance, the leafy seadragon actually sways like the seaweed it disguises itself as. And, of course, there are animals who adapt their coloration to the environment. The arctic hare will shed its coat, moving from winter white to brown or gray in the summer.
With mimesis, animals camouflage themselves as something that would be of little interest, whether a dead leaf or a twig. In doing so, these animals are passed over by predators who mistake them for something different or barely notice them at all. With a myriad of choices for disguise, animals of all types turn to camouflage to help them survive.
