The Hunt [BBC]

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

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

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

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

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.

Scientists attempt to preserve the world's top predators, combining natural history footage with human drama.
