This is what I got from a wikipedia page ( http://en.wikipedia.org/wiki/Arctic#Anim… ):





Animals


Polar bears have white fur so they can camouflage in the snow. This helps them to sneak up on seals when they’re hungry.


The wolverine is part of the weasel family, and lives in holes in the ground. Though it is a small animal, it is very powerful.


Arctic foxes are hard to spot in the snow because of their thick white fur. In the summer, their fur turns a brownish-grey colour.


The Ptarmigan is a type of bird which nests in the snowy mountains, where they raise their young.


Beluga means “white one” in Russian. Adults are white and the young are grey. This is so that the young can’t be seen easily by their predators. (Type of whale)


Some other animals include the Arctic Wolf, Ringed Seal, Lemmings, and the Arctic Hare.
