Investigating extraordinary feats and strange powers of animals. A look at animals that possess senses more powerful than humans: sharks, dolphins, hippos, parrots, killer bees, rhinos, pelicans and elephants.
A look at wildlife in hostile environments, including glow-worms, condors, thorny devils, emperor penguins and polar bears. High in the mountains, deep underground, out in the deserts and at each of our vast frozen poles, animals have had to develop extraordinary resilience to survive. There are many challenges faced by animals living in extreme environments. Superbly adapted to these inhospitable habitats, their fortitude and resilience.
Fresh water is our most precious resource and it defines the distribution of life on land. Follow the descent of rivers from their mountain sources to the sea. Watch spectacular waterfalls, fly inside the Grand Canyon and explore the wildlife below the ice in the world's deepest lake. Witness unique and dramatic moments of animal behaviour: a showdown between smooth-coated otters and mugger crocodiles; deep-diving long tailed macaques; massive flocks of snow geese on the wing and a piranha frenzy in the perilous waters of the world's largest wetland.
The hunt for life within the long-dead bones of dinosaurs may sound like the stuff of Hollywood fantasy - but one woman has found traces of life within the fossilised bones of a T rex. Dr Mary Schweitzer has seen the remains of red blood cells and touched the soft tissue of an animal that died 68 million years ago. Most excitingly of all, she believes she may just have found signs of DNA. Her work is revolutionising our understanding of these iconic beasts.
