National Geographic voice:
"Many wild animals gain the white protective coloration during the winter season to easily hide in the snow from their predators. The skill of mimicry of some species is so unique and elaborated, that to an untrained eye they seem to be invisible even when looking directly at them.
However, predators, especially their natural enemies, know how to find their prey. For example, on this picture you can see the wild rabbit (Imaginatius Cuniculus) perfectly indiscernible among the snowy surrounding, who just got attacked by a white-furred stoat. The stoat had bitten fast into the rabbit's neck and holds it firmly. There is only a little to no chance the rabbit will escape this deadly grasp."
