There is a strong evolutionary pressure for prey animals to avoid predators through camouflage, and for predators to be able to detect camouflaged prey. There can be a self-perpetuating coevolution, in the shape of an evolutionary arms race, between the perceptive abilities of animals attempting to detect the cryptic animal and the cryptic characteristics of the hiding species.
Camouflage is weakened by motion, but active camouflage could still make moving targets more difficult to see. However, active camouflage works best in one direction at a time, requiring knowledge of the relative positions of the observer and the concealed object.

Communication is important for animals throughout the animal kingdom. For example, since female praying mantids are sexually cannibalistic , the male typically uses a cryptic form of display. [ 2 ] This is a series of creeping movements executed by the male as it approaches the female, with freezing whenever the female looks towards the male.
Surviving in the wild is no easy feat, but thanks to evolution, many animals evade their predators with a clever deception of the eyes. Since the beginning of time animals have either adapted or ...

New material may enable simpler and less expensive camouflaging technology, researchers say
Camouflage is the concealment of animals or objects of military interest by any combination of methods that helps them to remain unnoticed. This includes the use of high-contrast disruptive patterns as used on military uniforms , but anything that delays recognition can be used as camouflage.
Animals such as frogs are very good at detecting motion, [1] making motion camouflage a priority for predators. Motion camouflage is camouflage which provides a degree of concealment for a moving object, given that motion makes objects easy to detect however well their coloration matches their background or breaks up their outlines .
