Many animals have evolved to exhibit some form of camouflage, which is an adaptation that allows animals to blend in with certain aspects of their environment. Camouflage increases an organism's chance of survival by hiding it from predators. This gives the animal a higher probability of being able to successfully reproduce and carry on the species. Camouflage is also used by some predators as a tool for hunting. For them, being able to blend in with their environment gives them an element of surprise and increases their chance of successfully obtaining food.
