Sea Otters are a keystone species in that they help keep their ecosystem in balance. At one point, humans hunted sea otters almost to extinction for their fur. But now, the major threats are pathogens, parasites, and oil spills. Join host this weekend Jeff Corwin as he travels to the California Coast and works with the men and women of the Monterey Bay Aquarium to rescue stranded sea pups, place them in maternal care at the aquarium, and help them develop survival skills for their eventual release. It's a monumental effort, but all worth it, to save these loveable creatures!
