Musk Ox
Ice Age survivor of the tundra — shaggy qiviut, curved horns, and a defensive circle.
Least Concern
Ovibos moschatus
Overview
Musk oxen are stocky Arctic ungulates wrapped in dense underwool (qiviut) and long guard hairs. When threatened, herds form a defensive circle with calves inside and horns facing out.
For Canada collectors, a musk ox on the Barrens is a rare High Arctic card — prehistoric silhouette against the tundra.

Bulls clash in rut with head-on charges; calves stay close to cows.
How to identify
Massive shaggy brown coat, short legs, and curved horns with a broad boss in adults.
Stocky body and low-slung profile built for Arctic wind.
Interesting facts
- 01
