  1. The Amazing Musk Ox By Elliott Seo 4A Seoul International School 2007-2008

  2. Habitat The map shows where the musk oxen live. The red color shows the “original“ places they lived in the beginning of the 19th century. The blue color shows the areas where muskoxen have been introduced with success in the 20th century.

  3. Adaptations MUSK OXEN are large animals with long fur coats. Males and females have horns. A musk oxen's coat keeps it snug and warm. For winter they grow thick undercoats of soft brown fleece, and thick overcoats of shaggy, long straight hair that hangs down. Inuit use the soft undercoat for weaving a luxurious wool.

  4. Food Web MUSK OXEN eat grasses, lichens and willow trees. The herd keeps moving while they are eating. Their hooves spread out allowing the muskoxen to walk on snow without sinking too deep. The sharp hooves help them dig up the grasses that are buried under the snow.

  5. Interesting Fact # 1 In the early 1900s the musk oxen were over-hunted and almost disappeared. They were easy to kill when they formed a circle. Musk oxen were hunted for their meat and the hides were sold. In 1917 the Canadian government made a law against killing the musk ox. Now there are about 60,000 musk oxen living in Nunavut. The musk ox gives off a "musky smell" when excited. Family: males - bulls; females - cows; babies - calves

  6. Intresting Fact#2 Bulls will compete for breeding rights by ramming their heads together on the horn bosses until one bull walks away.  They will back apart over 50 meters and ram bosses at speeds equivalent to a car hitting a wall at close to 20 miles per hour!  They will repeat this behavior until one bull gives up and leaves the area.  Each boss is composed of up to seven inches of horn and bone to protect the brain.  Immature bulls will avoid contests with mature bulls because their bosses do not fully developed until they are four years old or older.  It’s no wonder that bulls generally have a shorter lifespan than cows!

  7. Interesting Fact#3 Musk oxen are very herd-oriented animals, with some herds reaching up to 100 animals in size during winter months.  In summer and fall, harems will form consisting of over a dozen females, their young, and one bull.  The bull will drive all other bulls away from his group of girl musk oxen, with defenses becoming very aggressive as the breeding season approaches in the fall.  Bulls are known to even drive birds away from their group of females.  Bulls that do not have females will roam great distances and even join groups of non-breeding males.

  8. Interesting Fact#4 The most well known behavior of musk oxen is their defensive ring.  When they are threatened, the adults in a herd will form an outward-facing circle with calves in the middle.  If they are approached, an adult or two will charge from the circle to face the threat and the circle closes behind them.

  9. About Them • The musk ox measures from 4 to 5 feet tall at the shoulder. • It weighs from 500 to 800 pounds.
