Abstract
WHITE coloration of many animals in cold environments decreases the possibility of visual detection because of the lack of contrast between the animal and its white background. White hair thus provides concealing coloration for prey species such as arctic hare (Lepus arcticus), and for predators such as the polar bear (Ursus maritimus) and arctic fox (Alopex lagopus).
