Oceans Alive: Kingdom of the Coral Reef S01 E11 Mammals of the Sea

While on a study of polar bears in Canada's north, John Stoneman remembers work he did with other mammals of the sea, including the harp seal, sea lion, sea otter, manatee, dolphin, orca (or killer whale), pilot whale, the mighty humpback whale, and the small, ghostly beluga whale. Of all the underwater creatures, it is the marine mammal that man most identifies with and that becomes true for the Foundation team, too.
