Mammalian is a 2010 documentary film that follows Frank Wolf and Taku Hokoyama as they take on a 2,000 km canoe journey through the largest wilderness area in North America.

Their route travels from Yellowknife, YT to Rankin Inlet, NT through a region with one of the highest concentrations of land mammals on earth.

The pair encounter Arctic wolves, the caribou migration, musk ox and- most importantly- make the first ever recording of a rare and elusive creature not previously thought to exist in northern Canada.

With a sense of humour and purpose, they track down politicians, First Nation chiefs, elders and others living in the few communities that frame the wilderness in order to present a clear picture of the area and the issues that face the land and its people.

It aired on CBC's documentary (TV channel) in Canada multiple times through 2013.
