It begins at the end: Tau is dying; a slow shutting-down creeps over his body. Its time to reflect. His life is over but it was well spent.

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.

Man-eating sharks seemingly flock to South Africa's Second Beach. This remote coastline was once considered a surfer's best-kept secret, but now its regarded as Earth's most dangerous beach. Here, sharks don't simply attack; they kill. Gruesome attacks have claimed six lives in five years. Something has triggered bizarrely aggressive behavior in these predators, and biologist Matt Dicken is on a quest to find out why. Join him as he confronts the killers in their own domain.

On the harsh and unforgiving plains of central Namibia, Africa, a young honey badger named Grit has just left home to venture out in the great, wide world, but it won't be easy. Fewer than half of all young honey badgers survive their first few weeks on their own, as they deal with intense heat, starvation, and round-the-clock threats from the many predators of the savannah.

There are two phenomenal beasts that rule one of Africa's true wilderness areas - Buffalos and Lions. The first dominate the plains with bulk, power and aggressiveness. The second rule by fear and tenacity... And when they clash, dust chokes the air, sharp claws collide against impressive horns... and blood soaks the thirsty land.

Africa is a land of giants. Its powerful rivers sculpt the earth and form impressive valleys and waterways that are home to many imposing and powerful inhabitants. These are the rivers where massive elephants and hippos live, feed and drink, and where ancient crocodiles hunt and breed. They share the rivers with porcupines, the martial eagle, and the leopard.

A documentary that focuses on how animals born with unusual colours have a much harder struggle than normal. Follow white lions, a white baboon and a yellow crocodile.

A fascinating insight into three great African predators—lions, cheetahs and leopards— and their relationship with each other, and the rest of the African fauna. Their remarkable hunting strategies ensure their survival, but in the Mala Mala, South Africa, which will will the Big Cat Challenge?
