From the Arctic to the Amazon, this groundbreaking three-part series goes on a global expedition with world-renowned underwater cameramen, Doug Allen (Planet Earth) and Didier Noirot (Jacques Cousteau’s cameraman), as they capture spellbinding footage of these marine mammals. Ocean Giants looks at how cetaceans hunt, mate, and communicate, and follows scientists as they strive to uncover new insights about these animals.
The first hour, Giant Lives, enters the world of the great whales. In the Arctic, giant bowhead whales survive the freezing cold wrapped in fifty tons of insulating blubber two-feet thick, making them the fattest animals on the planet.
