TV naturalist Steve Backshall takes on six epic adventures to Guyana, Mexico, Namibia, Indonesia, Australia and South Africa, where along the way he encounters the world's most venomous snake, the Inland Taipan, gets perilously close to the largest carnivorous reptile in South America, the giant Black Caiman, attempts to track down the endangered Giant River Otter, and stakes out the feisty and fearless Honey Badger.
