Planet Earth: The Hunt

Following tigers, harpy eagles, chimpanzees, army ants and other predators.

Following blue whales, sharks, sea lions, frigate birds, dolphins and albatrosses.

The only option for the Arctic's top predators is to continually adapt.

In grassland or desert habitats, predators have an easy time spotting prey, but the prey can also spot predators.

Predators from air, land and sea come together on the coast; coasts are ever-changing; since opportunities do not last long, hunters must race against time.

The contests between predators and prey are the most dramatic events in nature.
