Muskoxen are an artifact species surviving from the late Pleistocene and the last glacial epoc. Muskoxen can be seen within the Preserve. They are herding animals that have long, dense, dark brown shaggy hair hanging nearly to their feet.
Females are considerably smaller.
Males and females have large horns which curve down close to the sides of the head with sharp, upturned tips. Muskox form herds of 3 - 100, but tend to stay in one area. When predators threaten, adults form a ring with the young inside. Occasionally, a bull will leave the ring to attack. Their sight and hearing is good, and when necessary can run rapidly.
