This bold new series from Sir David Attenborough takes viewers on a magical adventure across the greatest, yet least known parts of our planet - our oceans.
Discover alien worlds and bizarre creatures. Coral gardens flourish in absolute darkness. Narrated by Sir David Attenborough.
Coral reefs are home to a quarter of all marine species. Survival in these undersea mega-cities is a challenge with many different solutions. Narrated by Sir David Attenborough.
The big blue is a marine desert, far from shore, kilometres deep, with almost nothing to eat - and home to some of the most spectacular creatures on Earth.
It's our green seas, not the blue, that bring life to our oceans. Here sunlight powers the growth of enchanted forests of kelp, mangroves and prairies of sea grass.
At the coast, two worlds collide. Coasts is the story of how our Blue Planet's wildlife survives in this ever-changing world. It's a roller-coaster ride of heart-stopping action and epic drama.
