Odorous Animals

Musk-Ox-May-17-BlogThere’s a large, cattle-like animal which lives in the frozen tundra of North America. It’s not a reindeer, and it’s not a buffalo. Can you tell what it is from looking at the picture? It’s a musk ox.

So how did musk oxen get their name? Well, if you can get close enough to one you’ll see – or rather you’ll smell! During the mating season, male musk oxen produce a potent smell from special glands in order to attract females. This smell, or musk, was at one time prized by perfumers, and it’s that which gives the musk ox its name.

Musk oxen are large creatures, almost 2m tall and 2.5m long. But they look even bigger than this because of their thick coats. They have several layers of long, thick, woolly fur which keeps them warm. It’s so effective that musk oxen can survive temperatures as low as -40 Celsius. It’s as though they were adapted for living in the Ice Age. In fact, they look quite a lot like miniature mammoths (bit without the trunk!).

Their hooves are sharper than those of most bovines, and well suited for digging. They are experts at finding and excavating any plants, mosses or lichens covered by ice.

For most of the year musk oxen live in large herds of up to 70 animals. This all changes in summer though when the mating season arrives. The males in a herd will fight until one emerges as the dominant bull. All the other males are driven away leaving just one to mate with all of the females. This only lasts for a couple of months and then the outcasts can return, ready to try their luck again next year.

Musk oxen have a few enemies – polar bears and arctic wolves being their main predators. Surprisingly, musk oxen rarely run from an attacker. Instead they form a circle facing outward with any youngsters protected within. To catch a meal any predator must make it past a wall of muscle and horn.

Musk oxen are, I’m happy to say, not at any risk of extinction, although they were almost wiped out in the 1800s. We humans hunted them for their meat and their fur but in 1917 the Canadian Government completely banned musk ox hunting.
