As such, the better the animal matches its background, the less likely it is to be detected by either predator or prey [28]. This is not to suggest however that it is a conscious decision on the part of the species in question. This can include color change occurring in seconds, minutes, and hours, to longer term changes associated with phenotypic plasticity and development. Emus have long necks, sharp beaks and small ears. From insects to reptiles, amphibians to mammals, many animals are camouflaged giraffes, zebras, lions, tigers, coyotes and the majority of female birds typically display coloring that suits their environs and helps them hide.
