Sir David Attenborough unveils the two stunning underwater realms of Saudi Arabia - the flamboyant Red Sea and the contrasting hot muddy Gulf, capturing for the first time the rare event of Palolo worms spawning at night.

In a seasonal special, Gordon Buchanan meets the animals who live in nature's winter wonderlands. He reveals their survival secrets, from the polar bear mother who gives her cubs the best possible start in life to the owl that finds food hidden beneath a blanket of snow, plus the plucky penguins that huddle together to keep warm. Gordon also unwraps the lives of our favourite Christmas characters - those wonderful reindeer and our very own robin redbreast!

Otters are playful, adaptable and champion swimmers - they've captivated cameraman Charlie Hamilton James for the last 25 years. He's filmed them more than anyone else and now, through the eyes of three orphaned river otters, a set of groundbreaking experiments and some incredible wild encounters, Charlie wants to reveal their survival secrets and exactly why he believes they're so special.

In a remote corner of Antarctica, a group of killer whales capture their prey in the most extraordinary fashion. Swimming together, they create waves so powerful and accurate, they can wash a seal right off a piece of floating ice—some of the most sophisticated behavior in the animal kingdom. The hunting technique of pack-ice killer whales has intrigued scientists for decades, and there is still so much unknown about the species. Each scientist on the expedition hopes to discover new truths about these whales.
