Everyone loves giraffes, but what do we really know about them? Dr Julian Fennessy starts to reveal their secrets - the most important being that they are disappearing. In an urgent and daring mission, with a determined Ugandan team, he plans to round up 20 of the world's rarest giraffe to take across and beyond the mighty Nile River. The stakes are high, but if they succeed the reward will be a brighter future for an animal we have somehow overlooked.

Jaguars are South America's supreme predator, but they are also one of the most elusive animals on the planet. We follow a pioneering team in Brazil as they track and follow individual wild jaguars to gain amazing new insights into their lives. With jaguars increasingly under threat, every cat counts. So when two young jaguar cubs are tragically orphaned, the team needs to use all their new-found knowledge to help the cubs return to the wild.
