World of the Wild: The Open Ocean

Editor's Take
Venturing into the open ocean that covers most of the planet, this episode looks at how marine life establishes itself from the sunlit surface down to the depths. Its 4K photography underscores the interdependence that binds that life together, and its fragility. Concise and absorbing, it favors a sense of the ocean's vastness over exhaustive detail.
