Howling: Wolves howl as a signal to other wolves, telling of the beginning and ending of a hunt, of a wolf separated from its pack, as a warning to other wolf packs, and simply for the fun of it.

Anatomy: Arctic Wolves are smaller than other wolves and have long, thick white fur. Adults are about 3 ft (0.9 m) long plus a 1 ft (30 cm) long tail. Like other wolves, they have strong jaws with sharp teeth, including long canine teeth which tear flesh. Wolves have very good eyesight, acute hearing, and a keen sense of smell which help them hunt.

Hunting and Diet: Wolves hunt in packs and often prey upon animals that are much larger that they are. They mostly eat caribou, and they kill their prey with a devastating bite on the neck. Wolves almost never attack people. They swallow food in large chunks, barely chewing it. Wolves can eat up to 20 pounds (9 kg) of meat at one meal. When they return from the hunt, wolves regurgitate some of the food for the hungry pups.
