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.

An Otter Study is a 1912 British short black-and-white silent documentary film, produced by Kineto, featuring an otter in its natural habitat, including groundbreaking footage of underwater hunting scenes. The film provided a novel treatment of the creature, which had previously appeared on film only as the victim of hunt films, with the unique underwater footage, shot by a cameraman behind glass in a tank concealed on the bed of the river in the opening scene, and a concluding scene, excised from the surviving print, in which it escapes the hunters. It was long thought lost until footage from a 1920s Visual Education re-release of the film, re-edited under the supervision of Professor J Arthur Thomson of Aberdeen University's Natural History Department, was rediscovered.
