The soldier pulls on her ghillie suit and walks into the field. She lays down in the grass and disappears. Is she still there? Of course. But can you see her? No. When our brave soldiers in the military wear camouflaged clothing in battle, they use the same tricks that animals use to blend in.
Camouflage is an adaptation that helps an organism blend in with its surroundings. Blending in helps the animal avoid predators and increases its ability to survive. Camouflage in the animal kingdom works in various forms. Organisms may use their ability to blend in for different reasons, but ultimately it helps an animal to survive and reproduce.
Camouflage isn't just about color. True, it may be a pattern on an animal’s coat or wings that lets it blend in. But it could also be the ability of an animal to mimic something else. Camouflage also includes coloration that is noticeable, but makes a body outline difficult to see.
Usually, animals that use camouflage mimic things a predator won't notice, such as plants or rocks.
Another form of camouflage is disruptive coloration. This occurs when an organism stands out against its surroundings, but has colors that break up its outline. Many animals have stripes or spots that help them to blend together when in groups. This makes it difficult for a predator to detect just one of these animals.

Leaf-tailed geckos not only have tails that resemble leaves, their skin also has a pattern that resembles dead leaves or tree bark.
