Arctic foxes live in the tundra regions of Greenland, Alaska, Russia, Canada, Norway and Scandinavia. They are also found In Iceland where they are the only native land mammal.
Arctic foxes are well adapted to the rocky, barren tundra. Their fur is thick and deep, even on their feet, which protects their small, compact bodies from the frigid environment. Lemmings are a diet staple, but when they are scarce, the arctic foxes forage polar bear leftovers. Their excellent hearing is a major advantage when hunting prey beneath the snow. They leap into the air and pounce on the snow until it breaks, and they land directly on their meal.
The average length of the male arctic fox approaches 34 inches, while females are slightly smaller. Arctic foxes are known to mate for life.
