Recommended: A Seal's Life

I'd never watched this 2007 documentary before, but it was clearly a painstaking effort to document everything about a remarkable creature, the Northern elephant seal. Dr. Sylvia Earle, sounding like the science teacher you always wish you had, does the narration. The videography is simply beautiful, and there are facts of interest for everyone: I'd read about the species but never knew how it had survived almost certain extinction. A tour of a kelp forest is one of the interesting byways taken in following the seal's migration.
