Dall sheep

Dall sheep

Dall sheep have a broad habitat. They are a subarctic as well as arctic animal. The most northern group of these animals live in the Arctic National Wildlife Refuge. The alpine ridges, meadows, and steep, rocky slopes that have "escape terrain" are where the dall sheep live. The flock likes to rest and feed on these slopes. They are also there to keep away from predators because they can flee to the rocks easier than their predators. Some of these predators would include bear, golden eagles, wolves, and humans.

The collared lemming

The collared lemming


The collared lemming is one of the most interesting Arctic animals because of how it has adapted to the cold Arctic temperatures. It is not a "true" lemming although it is closely related to the lemming. It is a small rodent that burrows under the snow or ground making extensive runways and nesting areas. The collared lemming grows enlarged claws on the third and fourth 'fingers' of its front feet.

The arctic tern is a relatively small bird. It is also one of the most determined. Even though it is small it is still able to accomplish the remarkable feat of migrating over 22,000 miles (35,000 km) each year. The distance that it migrates is the longest of any bird. This mileage would be accurate if it flew in a straight line to where it was migrating to and from. But since it takes a lot of excursions the distance it flies each year is even greater. In fact the arctic tern almost never lands and is known to be in daylight more than dark because of its migration schedule.

The arctic fox lives farther north than any other fox. They are well adapted for the cold harsh weather of the Arctic. The arctic fox can hunt lemming that they can't see beneath the snow, but if the arctic fox can't kill enough to eat, it will settle for leftovers from other animals.
