Diablo the giant otter lives in a lake in the jungles of Peru, with his unruly family of six cubs. Even at the tender age of six months, they need to learn how to survive in this dangerous paradise. Their dad teaches them to swim and eventually to catch piranha for themselves, but they must also learn to stay away from the neighbours from hell - the giant caiman. These large members of the crocodile family are a real threat to the giant otter family and Diablo must go to extraordinary lengths to try to protect his cubs. Charlie Hamilton-James returns to the place he first filmed Diablo. Following the family over several months, sometimes in very difficult conditions, he discovers how perilous a home this is for the cubs and watches them develop under the careful guidance of their father. He also films remarkable scenes of the giant otters fighting caimans.

Sir David Attenborough chooses his favourite recordings from the natural world that have revolutionised our understanding of song. Each one - from the song of the largest lemur to the song of the humpback whale to the song of the lyrebird - was recorded in his lifetime. When Sir David was born, the science of song had already been transformed by Charles Darwin’s theory of sexual selection: singing is dangerous as it reveals the singer’s location to predators, but it also offers the male a huge reward, the chance to attract a female and pass on genes to the next generation. Hence males sing and females don't. Today, new science in the field of birdsong is transforming those long-held ideas. Scientists are discovering that, in fact, in the majority of all songbird species, females sing - and it is only now they are being properly heard. Through this revelation and others, we can understand that animal songs are marvelous examples of the spectacular survival strategies that species have developed in order to stay alive.
