The sea otter (Enhydra lutris) is a marine mammal that primarily lives on the northern coasts of the Pacific Ocean.
Other species in the otter subfamily (Lutrinae) are sometimes mistakenly referred to as "sea otters" when seen near coastal areas. These include the Eurasian otter (Lutra lutra) and the North American river otter (Lontra canadensis)
