Muskox (Ovibos moschatus), Bering Land Bridge National Preserve, 2015.

True to its name this Arctic mammal of the family Bovidae emits a strong musky odor to attract females during mating season. However, it may be surprising that they are members of the subfamily Caprinae of the family Bovidae, so are actually more closely related to sheep and goats than to oxen. Ovibos literally means "sheep-ox" in Latin. Both male and female have long, curved horns. Their thick coat and large head makes the animal appear larger than it actually is, which is about half the size of a bison (even though the two are often wrongly compared!) In modern times, muskoxen were restricted to the Arctic in Canada, Greenland and the U.S.; however, the Alaskan population went extinct in the late 19th or early 20th century - possibly due to excessive hunting and/or adverse climate change. Muskoxen were reintroduced to Alaska in the early 1900's and by mid 1900's introduced to Canada (even though ancient muskox remains had never been found in the suitable Canadian ecosystem).
