Pole to Pole with Will Smith: Season 1, Episode 3

1 - 3: The Amazon: Dark Waters

Will, Bryan and Carla join local Waorani elder Penti Baihua in the Amazon, in search of the world's biggest snake: the giant green anaconda. They carefully remove just one scale from the 17-foot snake's skin. Will's fear turns into relief, then joy. The single scale can reveal the health of the entire ecosystem — crucial for the future of both wildlife and the Waorani.
