The Woman Who Swims with Killer Whales

The killer whale is one of the most feared predators in the ocean and most would consider it madness to enter the water with one.

But there's been an unusual number of deaths recently and Ingrid is on a mission to find out what is going on. Her findings reveal disturbing new information about the health of our oceans.

Animal House

Sir David Attenborough tells the stories of the world's best animal architects. There are house-proud bower birds, who only find a mate if they decorate their homes perfectly. There are hornets, who build electric central-heating systems, and the star-nosed mole whose house is so well designed that his favourite meal of worms literally drop in for dinner. From larders to nurseries and from high-rises to subway systems, Attenborough shows that the animal architects have designed it way before we humans.

Africa's wildest river is home to the most spectacular wildlife. Hippos fight for territory while herds of elephant, water buffalo and zebra depend on it for life. In the wet season the rains burst the riverbanks and everyone, including people, must move whilst fish swim through the villages. In the dry season the creatures fight over the few pools of water while predators prowl. At its heart it plunges over Victoria Falls and into wild ravines before draining into the Indian Ocean, where storm clouds cycle the water back into the heart of Africa.
