Blue Planet II

Using cutting-edge technology, go on a journey from the intense heat of the tropics to the planet's frozen poles to reveal new worlds and extraordinary animal behaviours. The journey starts in the tropical coral reefs, the most diverse ocean habitat.

An epic journey into the unknown, a realm that feels almost like science fiction.

Coral Reefs are vibrant undersea cities where life has found ways to survive.

The big blue is the world's greatest wilderness, far from shore and many kilometers deep.

From forests to undersea prairies, it is the green of the sea that brings life to oceans.

Coasts are the most changeable habitats of the ocean world.

Pioneers strive to protect the ocean from the effects of human activity.
