camouflage

n. the use of cryptic coloration and vocal signals that are difficult to localize in order to conceal one’s location (see crypsis). Many nonhuman animal species use camouflage to escape the notice of predators or to avoid detection by prey. For example, a stick insect looks like an actual stick in its environment, allowing it to blend in. Camouflage alarm calls have acoustic features that make it difficult to determine the caller’s location. See also countershading. Compare advertisement.
