BBC FROZEN PLANET II

In this sparking kingdom you'll meet mind-blowing animals who survive bitter snowstorms, towering icebergs and frozen seas. Dive under the ice to swim with seal pups, meet a Greenland shark who is easily 250 years old, and spot a snoozing windy walrus. Watch orcas sneak up on whales as they relas in the spa, and hold your breath as wolves play a deadly game of hide-and-seek in a frozen forest.

Discover the gripping stories from the new BBC TV series narrated by Sir David Attenborough.
