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.
In the air, Second World War fighters were often painted in ground colours above and sky colours below, attempting two different camouflage schemes for observers above and below. [163] Bombers and night fighters were often black, [164] while maritime reconnaissance planes were usually white, to avoid appearing as dark shapes against the sky. [165]
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 ...
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.
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 ...
Animals that live in groups often give alarm calls that give warning of an attack. For example, vervet monkeys give different calls depending on the nature of the attack: for an eagle, a disyllabic cough; for a leopard or other cat, a loud bark; for a python or other snake, a "chutter". The monkeys hearing these calls respond defensively, but ...
The barn owl’s brilliant white underbelly is the key to its success as a nocturnal hunter, allowing the bird to camouflage itself against the moon, according to new research. An owl’s ...
Some animals are capable of changing their colors with varying degrees of transformation. This may be a very gradual (shedding of fur or feathers) seasonal camouflage , occurring only twice a year. In other animals more rapid changes may be a form of active camouflage , or of signalling .
