The hooves of the polar bear and Musk oxen help keep their feet from feeling the coldness of he ground. The polar bear fishes out fish from the ice cold water underneath the ice or Ringed seals. The Musk oxen survives for about the same reason of havin thick fur for protection to not freeze. Their tusks help them push through the snow and pick lichen from the rocks to eat. Lichen is what they survive on to eat. The Artic fox is able to survive because it is small and does not need as much food as other animals. It also has thick fur, not as thick as the polar bear and oxen, but pretty thick. The foxes eat lemmings, birds, dead fish, and marine animals that wash to shore. They also follow follow polar bears to eat left over scraps. They live in dens, or in debris piles. |
