A look at the West Coast, where the Pacific Ocean shapes life in unexpected ways. Sea wolves roam the shorelines, hunting along the beaches and adapting to both the land and sea. Off Vancouver Island, a giant Pacific octopus sacrifices herself to protect her eggs, a rare and dramatic act to preserve the species. In Monterey Bay, sea otters navigate powerful waves to reach mussels, showing bold and seldom-seen behaviour. In the redwood forests of California, wandering salamanders leap from the treetops, an extraordinary survival tactic only recently discovered. Beneath the surface, deep ocean canyons are home to strange and diverse creatures. And off the coast of California, male blue whales race and roll at high speed. In all likelihood, they are competing to attract a mate - a spectacle never seen before. From the shores to the ocean depths, the West Coast is full of remarkable wildlife stories and surprising behaviours.
