It doesn't seem likely for polar bears. On the other paw, it seems a
definition question. Seals and walruses do it, so they are marine
mammals. However, they spend a great deal of time on land for a marine
mammal. Polar bears don't, so they are terrestrial mammals, although
they spend a great deal of time on and in the water for terrestrial
mammals. Land-based otters dive for food, but that makes them marine
animals? Lakeside mink probably don't, so they are land animals?
Muskrat and beaver and nutria apparently come ashore for food, as do
The dividing line seems, dare I say it, fluid.
