Darwin's Amazing Animals S2022E07 - Back from the Brink ― Sea Otter, Japan

Crowds line the cliffs of a remote cape to view 10 such creatures as they eat, care for their young and float on the water's surface as they sleep. But challenges remain. As their population increases, so will the effect on the area's marine resources, including clams, sea urchins and crabs.
