The Hunt

The open arenas of grassland and desert make up half of all land on our planet. In these exposed habitats, predators like cheetahs, bald eagles and lions can usually see their prey. But it works both ways:their prey can see them too. With nothing but open vistas, the element of surprise is hard-won, and predators must make their own opportunities.

The coast is the dynamic border between land and sea; powered by the tides and thrashed by waves, this is a world of continuous change. Opportunities never last long here, so hunters are always in a raceagainst time. The coast is the only place on the planet where predators from air, land and sea come together. Dolphins that leave the safety of the sea to fish, walking octopuses, ingenious monkeys, fishing wolves and the greatest gathering of feeding humpback whales come to the coast to hunt. For all, timing is everything.

The final episode of the series visits the frontline of the conflict with the world's top predators, meeting the scientists fighting to save them.

Crossing five continents and combining landmark natural historyfootage with real-life human drama, it checks the pulse of the earth's iconic animals, including lions, tigers, polar bears and blue whales.

With three-quarters of the planet's carnivores now in decline, can people find ways to live with predators before they disappear forever?
