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.

Camouflage is an exciting animal adaptation that allows many different types of animals to blend in with their surroundings. The chameleon is one of the most recognizable animals that camouflages ...
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 ...
The distinction between aggressive mimicry and predator camouflage depends on the signal given to the prey, not easily determined. Aggressive mimicry is a form of mimicry in which predators, parasites, or parasitoids share similar signals, using a harmless model, allowing them to avoid being correctly identified by their prey or host.
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 .
Bateson, in a much quoted passage, [6] describes crabs of the genera Stenorhynchus and Inachus: the crab tears a piece of seaweed in its claws, chews it, and then rubs it firmly on its body until it catches on the "Velcro-like hooked setae", [1] curved hairs which permit camouflage materials to be attached.
