The musk ox interacts with a wide range of species ranging from parasites to other large mammals. Since the musk ox isn’t the only herbivores living in the arctic, competition takes place between them and the Caribou for available vegetation (Elder 2005). Another interaction between musk ox and the environment would beArctic Fox concerning the shrubs it eats. When it eats, the musk ox’s digestive system churns the nutrients out of it and leaves the seeds to be secreted as waste in the environment. This secretion allows the spreading of the shrubs seeds and is referred to as mutualism. Another interaction that the musk ox has concerns arctic foxes (Muskox 2014). The arctic fox follows around in the musk oxen packed down tracks in the snow, which ultimately allows the fox to travel around easier. This has a positive effect on the fox but doesn’t harm the ox at all, so therefore the interaction being exhibited is commensalism.

Along with the three interactions listed above, the musk oxen also portray parasitism Tic shows parasitism in different ways. First of all, musk oxen have been known to have a parasite called Umingmakstronglyus pallikuukensis, or more commonly known as a lungworm (Kutz 2001). They feed off of the internal structures of the musk ox while creating massive infections causing their organs to fail (Kutz 2001).This overall causes a decrease in the muskoxen population while the lungworm has no effect at all. Another parasitism relationshipthat occurs between them and another organism is one more commonly known throughout the world: a tick. The tick burrows under the multilayered fur of the oxen and attach their pinchers to suck up blood (shown in the picture below). This effects the musk oxen in a negative way and could also cause them to contract certain diseases in their blood.

Since they live in the arcic and they're such large mammals, one would think they don't have to worry about predation, but that's not the case. The calves are at risk against predators like the arctic fox because of their age (Angier 2010). Since they're young, their fur is not to its thickest potential and the horns that they use for defense aren't developed. This makes them vulnerable to the herds of arctic foxes and their clever attacks. The arctic foxes first stalk the herd of oxen to pick out the weak calves (Elder 2005). After that, they start a full on attack on the herd and try to separate the calves from their elders. Even if they do end up successful, it's not necessarily the end of the battle. Musk ox's are very protective over their young and will go through a little pack of wolves just to regain a lost member of the herd (Elder 2005). Below is a video showing an interaction between a herd of musk ox and a pack of arctic wolves.

Another form of predation that is common for the muskoxen is being hunted by humans. Humans utilize the fur of the oxen and use the horns to make tools out of (Elder 2005). An uncommon form of predation that is seen in the arctic is an interaction between the musk ox and the grizzly bear. Although this is very rare, but below is a video that captures the interaction that occured (WARNING: May be gruesome).
