Among animals, variable snow camouflage is a type of seasonal polyphenism with a distinct winter plumage or pelage. It is found in birds such as the rock ptarmigan, lagomorphs such as the Arctic hare, mustelids such as the stoat, and one canid, the Arctic fox. Since these have evolved separately, the similar appearance is due to convergent ...
Arctic hare - In Newfoundland and southern Labrador, the Arctic hare changes its coat color, moulting and growing new fur, from brown or grey in the summer to white in the winter, like some other Arctic animals including ermine and ptarmigan, enabling it to remain camouflaged as the environment changes.

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 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 ...
On a longer timescale, animals like the Arctic hare, Arctic fox, stoat, and rock ptarmigan have snow camouflage, changing their coat colour (by moulting and growing new fur or feathers) from brown or grey in the summer to white in the winter; the Arctic fox is the only species in the dog family to do so.

Convergent evolution of snow camouflage in Arctic hare, ermine, and ptarmigan provided early evidence for natural selection. In his 1889 book Darwinism, the naturalist Alfred Russel Wallace considered the white coloration of Arctic animals.
