Blue Planet II - Episode Guide

Season 1

One Ocean

Episode: 1x01 | Airdate: Oct 29, 2017

One Ocean

Documentary series presented by David Attenborough which explores the planet's oceans. From the equator to the poles, new worlds and animal behaviours are revealed, from tool-using fish to mother walruses fighting for space on the ice for their tiring pups.

The Deep

Episode: 1x02 | Airdate: Nov 5, 2017

The Deep

The Deep takes us on an epic journey into the unknown, a world of crushing pressure, brutal cold and utter darkness. It's the largest living space on our planet, and today, scientists think there's more life here than anywhere else on Earth. This is our final frontier.

Coral Reefs

Episode: 1x03 | Airdate: Nov 12, 2017

Coral Reefs

Coral reefs are home to a quarter of all marine species. Survival in these undersea mega-cities is a challenge with many different solutions.

A turtle heads to the reef's equivalent of a health spa - but she must use trickery to avoid the queue. A remarkable Grouper uses the fish equivalent of sign language to collaborate with an octopus, flushing their prey out of hiding holes.

A metre-long, ferocious-jawed Bobbit Worm hides in its tunnel. Monocle Bream retaliate by squirting water to expose its sandy lair.

Big Blue

Episode: 1x04 | Airdate: Nov 19, 2017

Big Blue

Survival in the remote open oceans is tough and baby turtles use debris as rafts to stay afloat while the Portuguese man-of-war sail along hunting for fish. There's also footage of the "boiling sea" effect created by lanternfish being trapped on the surface of the water by predators.

Green Seas

Episode: 1x05 | Airdate: Nov 26, 2017

Green Seas

In the undersea forests of kelp, algae and sea-grass, there is competition between species and sea otters are seen helping Garibaldi fish protect their seaweed garden from sea urchins while the common octopus uses shells to create a coat of armour against sharks.

Coasts

Episode: 1x06 | Airdate: Dec 3, 2017

Coasts

The 620,000 kilometres of the world's diverse coastlines are a window to our oceans. After 60-mile journeys for food, puffins try to feed their young while dodging the attention of skuas.

Our Blue Planet

Episode: 1x07 | Airdate: Dec 10, 2017

Our Blue Planet

The human impact on our oceans is brought to light in a sobering finale – like the eight million tonnes of plastic that ends up in the oceans every year.
