Camouflage allows animals and objects to blend in with their environments to avoid detection. Examples of camouflage include leopard spots, military camouflage uniforms, and butterflies that resemble leaves. Camouflage is a form of visual deception that likely comes from the French word "camouflet" meaning to blow smoke in someone's face as a joke. Mimicry is when one species evolves to resemble another species in appearance, behavior, sounds, or location to gain a protective benefit from the resemblance. Mimics evolve to share characteristics with models to confuse receivers trying to identify them.
