Documentary using groundbreaking computer graphics and close-up photography to reveal the inner alchemy that gives four extraordinary hunters the edge, from the moment they detect their prey through to the vital kill. Soaring above the people of London is the fastest animal on the planet, the peregrine falcon, on a mission to kill for her chicks. Off the coast of South Africa the world's largest predatory fish, the great white shark, has just completed a 7,000-mile journey and is hungry for seal blubber. On the plains of Africa the fastest land animal, the cheetah, struggles to provide for her cubs as her enemies move in. And having survived a drought by entering into a state of suspended animation, the prehistoric Nile crocodile is poised to ambush his dinner.
The first programme shows how sharks are the ocean's great predators, living in every ocean and hunting in every way. Blacktip sharks hunt in huge packs and herd fish into baitballs, tasselled wobbegongs are ambush hunters, Greenland sharks live under the arctic ice, and whitetip reef sharks are the masters of hunting at night. The finale shows the great white in its hunt for fur seals off the coast of South Africa.
Footage of wildlife inhabiting underwater kelp forests, including thousands of giant cuttlefish spawning along a restricted area of rocky reef off the south coast of Australia. Males outnumber females 11 to one, which leads to fierce competition. Larger males use brute force to drive off competition, while their smaller rivals use deception by mimicking the appearance of females. The programme also features tiger sharks hunting for green turtles in fields of seagrass and spider crabs trying to avoid predators while they shed their shells.
