The camouflaging strategy

If a subject moves, the eye can see it helped by various elements that are correlated to the visual capacity of the subject following the action, even a shadow that passes rapidly leaves a sign on the retina, and so it is possible to find its origin. When instead there is no movement, the eye can only see a different shape on a coloured background. The hunting instinct is turned on, in fact, by determined “research images” , i.e. shapes and colours that immediately stimulate the preying instinct, and whatever does not belong to these images, does not arouse much interest. And this makes you understand the importance of camouflage in the animal world, as a particular example of adaptation to the environment: the preys and the predators have in fact had to “invent” strategies to increase the possibilities of capturing their prey, or of escaping from the possible predators.
