Episode 3: Open Ocean

BBC One - The Blue Planet, Open Ocean

Looking at the hunting skills of whales, dolphins, tuna, shark and rapier-nosed billfish.

David Attenborough narrates a natural history of the oceans. The deadly game of hide-and-seek played by the sea's charismatic hunters - whales, shark and billfish.

This programme focuses on the predatory skills of some of the most charismatic hunters found on the planet: whales, dolphins, tuna, shark and rapier-nosed billfish. The open ocean is unimaginably immense - it covers more than 360 million square kilometres of the Earth's surface. Much of this huge expanse of seawater is marine desert with virtually no sign of life. Yet the fastest and most powerful survive, playing a deadly game of hide-and-seek with their prey. This charts how they track down prey in the seemingly featureless seas, following the extraordinary life of yellowfin tuna from a minute egg to a 200 kilogram, voracious predatory giant.
