Large Mammals
Reindeer
Unlike other members of the deer family, both males and females grow antlers. Their nostrils are specially adapted to warm cold air as it enters. The hair is hollow, providing warmth and the hooves are specially adapted to walk on snow. These animals travel farther than any other terrestrial mammal, going up to 3200 miles during migration. Julius Caesar provided the first written description in the 1st century B.C.
