Polar Desert
Animals
Arctic fox
Animal Adaptations
furry soles, short ears, and a short muzzle—all-important adaptations to the chilly clime. Arctic foxes live in burrows, and in a blizzard they may tunnel into the snow to create shelter

Walrus
Animal Adaptations
A walrus can use its tusks to pull itself out of the water onto the ice, or to break holes in the ice for breathing when it's swimming underneath.
Tusks are also used for defense against predators. Males can grow tusks up to 100 centimeters long, or just over 3 feet
Penguins
Animal Adaptations
They have thick skin and lots of fat (blubber) under their skin to keep warm in cold weather. They also huddle together with their friends to keep warm.
Narwhals
Animal Adaptations
To escape from predators such as walruses and polar bears Narwhals have adapted to hold their breath for a long time so they can dive deep down into the ocean away from the predators
As Narwhals swim in very cold water they have adapted to grow a thick layer of blubber to maintain a healthy body temperature

Emperor Penguin
Animal Adaptations
Emperor penguins have the ability to 'recycle' their own body heat. The arteries and veins lie close together so that blood is pre-cooled on the way to a penguin's feet, wings and bill and warmed on the way back to the heart. Emperors' feet are adapted to the icy conditions
