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 ...
In the words of camouflage researchers Innes Cuthill and A. Székely, the English zoologist and camouflage expert Hugh Cott's 1940 book Adaptive Coloration in Animals provided "persuasive arguments for the survival value of coloration, and for adaptation in general, at a time when natural selection was far from universally accepted within ...
The Arctic hare [2] (Lepus arcticus) is a species of hare highly adapted to living in the Arctic tundra and other icy biomes. The Arctic hare survives with shortened ears and limbs, a small nose, fat that makes up close to 20% of its body, and a thick coat of fur. It usually digs holes in the ground or under the snow to keep warm and to sleep.
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.

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.

NFP Green, Standard issued camouflage since 2019 in the Royal Netherlands Army. [50] [51] This camouflage is designed to be used in green areas, woods, and urban areas in Europe. Three additional colour variations are in use and are shown below. An arctic version of the NFP is being considered. [52] M19. NFP-Multitone. Flecktarn: 2019
European hare (above) compared with a mountain hare Stuffed mountain hare, showing the winter pelage The mountain hare is a large species, though it is slightly smaller than the European hare . It grows to a length of 45–65 cm (18–26 in), with a tail of 4–8 cm ( 1 + 1 ⁄ 2 –3 in), and a mass of 2–5.3 kg ( 4 + 1 ⁄ 2 – 11 + 3 ⁄ 4 ...
The snowshoe hare is also distinguishable by the black tufts of fur on the edge of its ears. Its ears are shorter than those of most other hares. In summer, it feeds on plants such as grass, ferns, and leaves; in winter, it eats twigs, the bark from trees, and plants and, similar to the Arctic hare, has been known to occasionally eat dead ...
