The Amazon is one of the wildest and least explored parts of the planet. Encompassing 6 countries and 2 million square miles of forest, river and floodplain, it has the highest diversity of life on the planet, but what lies below it is truly shocking. In its deep muddy rivers, clear streams and expansive floodplains a freak-show of fish life has exploded, with some of the strangest shapes and weirdest adaptations on Earth. Hiding in the vast rivers and streams is an electric grid, a bizarre community of fish with a highly sophisticated electric sixth sense. Using electricity, these "Super" fish can communicate wirelessly, control each other remotely and emit shocks that can stop a human heart. This cryptic world has mystified scientists throughout the ages. Now an intrepid scientist, Will Crampton ventures back into the dark jungles where the inspiration for our technology driven world first emerged, in an attempt to unravel their secrets and unlock the electric code.

In southern Africa, a pride of lions has rewritten the rules - by learning to take down elephants. In this follow up to Africa's Giant Killers, we join the pride at the start of the rainy season. As the elephants depart, a catalogue of dramatic events unfolds. The pride males turn against each other, an inexperienced mum puts her newborn cubs in mortal danger, a rival group of lions challenge the pride for its territory and, when lightning strikes, fires burn day and night. When the dust eventually settles, the pride is left with only one choice - to face their old foe the elephants or risk starvation. The final showdown awaits.

Natural World is a nature documentary television series broadcast annually on BBC Two and regarded by the BBC as its flagship natural history brand. It is currently the longest-running series in its genre on British television, with more than 400 episodes broadcast since its inception in 1983. Natural World is produced by the BBC Natural History Unit in Bristol, but individual programmes can be in-house productions, collaborative productions with other broadcasters or films made and distributed by independent production companies and purchased by the BBC. Natural World programmes are often broadcast as PBS Nature episodes in the USA. Since 2008, most Natural World programmes have been shot and broadcast in high definition.
