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 series studies an array of predatory models in each location, and then looks at why particular animals are able to lift themselves above the rest. Sometimes starvation drives predators to the extreme – as in Savute, where a particular lion pride unlocks the key to hunting elephants. Or vicious competition drives them to hyper-efficiency – as in Ndutu, where cheetahs team up to out-hunt hyena mega-clans… Or sometimes the chance to kill comes so rarely that when it does appear every effort is put into the killing blow – as at the Grumeti river, where massive crocodiles wait an entire year for one feast This is the NatGeo version of "Africa's Predator Zones"
