The North American river otter, aka Canadian otter, is found in North America from Canada and Alaska to the Rio Grande. They steer clear of arid deserts and treeless Arctic regions. These otters prefer riparian zones and can be found in the same locations as beavers. They can live around both marine and fresh water ponds, lakes, rivers, streams, and marshes. These cute critters are relatives of weasels, stoats, mink, wolverines, and badgers. Like all Mustelids, they have scent glands that they use to mark their territory. North American river otters are listed as Least Concern by the IUCN.
