Life on the Edge (S01E03)

This tale unfolds along a breathtaking 4,000-mile coastline. Starting at the frigid and treacherous waters of Cape Horn, where determined rockhopper penguins face formidable obstacles to nurture their chicks, and extending to the northern reaches, where massive elephant seals compete fiercely in the sweltering desert heat. Orcas storm the beaches, snatching seal pups to feed their offspring. While humans also seek the ocean's riches, these rugged shores demand resilience and courage.
