Tundra animals

I will start with the arctic fox. They have adapted because they have long fluffy fur and fur on the bottom of their feet to keep them insulated. It has short leg and ears to keep the heat in. It's fur changes in summer and winter for cammouflage. It is a scavenger so it could follow around polar bears and eat what is left of its meals. http://nonagraphics.com/images/Arctic-Fox-00001b.jpg They make burrows to sleep in, in the ground that isn't frozen and to help keep them keep warm they put their fluffy tails around their body.

Polar bears seem to be white but it is actually its fur reflecting the sun. There are two layers of fur and has inches of blubber underneath that. Their skin is also black which absorbs the heat, so they can easily get overheated. They love to swim so they have long necks that stay above water. They have sharp claws and teeth to catch there food like seals and fish. They are now endangered because the pollution we put into the atmosphere is causing the ice caps to melt which is the polar bears natural habitat.

Lastly the musk ox, it has 24 inches of hair that insulates them and keeps them warm. It stays in herds throughout its life. the advantages of this is that they will warn each other of danger by stampeding. They will run up to high groung then turn and form a circle to protect the young. They are very sturdy so they aren't easily moved. They can withstand bitterly cold climates because of their hair and woolly underhair which prevents frost and the cold.http://www.alaskaone.com/wildlife/images/muskox.jpg
