"Circle of Defense.
The musk ox lives in herds from 12 to as many as 100, staying close together for protection.
When an enemy threatens a herd of musk oxen, the musk oxen will form a circle, keeping the calves in the middle. The largest males will charge out, threatening the enemy with their horns. The herd will tighten the circle when one leaves the circle, keeping the circle tight and safe.",
"Mop-head.
Musk oxen look like dust mops on four legs. No other hoofed animal lives as far north as the musk oxen. Their woolly undercoat and 24 inch long hair provide them insulation in the harsh arctic conditions.",
"Last one standing.
The lifespan of a musk ox is about 24 years. Musk oxen co-existed with mammoths and have survived hunters and climate changes that caused the extinction of other species.
Their only serious predator is the Arctic wolf, although polar bears may attack if they are weak or injured. The Eskimos of Northern Alaska call the musk ox 'Oomingmak', which means ‘animal with skin like a beard’.",
"A light musk.
The musk ox gets its name from the odor produced by glands beneath their eyes.
The male has horns that curve down beside its face, out at the ends and then nearly meet at the top of their head in what is called a ‘boss’. The female has smaller horns, and her head is covered with whitish-gray hair.
The musk ox weighs between 400 and 885 pounds and reaches a length of 7 feet.",
"Last line of defense.
When threatened musk ox form a defensive formation.
They run to a higher location, then turn and stand shoulder-to-shoulder in a circle. They lower their heads and with their heavy heads and horns, form an impenetrable wall.
Their young are kept safe in the inner circle."];
