The Revillagigedo Islands, about 200 miles off the coast of Mexico, may not look like much on the surface, but beneath is one of nature's best-kept secrets: a home to some of the greatest concentrations of fish in the world. This is the only natural juncture for miles in an otherwise empty Pacific Ocean, and a crucial area for migrating sharks and other apex predators. Enter a world where whitetip sharks, giant lobsters, and moray eels share living quarters, humpback whales breed, and mantas and tuna feast on bait in this land of plenty.

First told at the dawn of Christianity and at a moment of crisis for the Jews, the story of Masada has long fired the imagination of believers and non-believers alike. Yet, for most of recorded history, it’s been little more than a legend. Then, in the middle of the 20th century, everything changed. A mounting body of archeological evidence emerged – a ruined mountain fortress, a siege ramp threatening its walls, a series of ancient Roman camps. Taken together, they pinpoint Masada on the map. This is the indisputable site of an epic fight between the Roman army and a besieged community of Jews. But as the siege wall rose and their enemies prepared a final attack, did they really choose mass suicide and martyrdom over surrender?

Herman Melville’s epic ocean adventure “Moby Dick” is an American masterpiece. But was this stirring tale of violence and revenge simply an allegory, or were there real giants of the deep deliberately attacking whaling ships? With the help of centuries old witness accounts and modern day science, we explain how the legend of the great white whale came to be.

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.
