A BBC film crew has captured footage of a gigantic green anaconda in the Amazon rainforest in Ecuador.
The encounter took place during filming for a new series called 'Tribes, Predators and Me' in which presenter Gordon Buchanan meets up with a hunting family who catch and release anacondas - a traditional activity seen as a demonstration of strength and bravery among the local tribes.
In a remarkable stroke of luck the film crew just happened to be there when the hunters caught the largest anaconda they had ever seen - a 17ft behemoth that took several men to lift from the water.
The enormous reptile provided the team with a wealth of scientific data before being released back in to the wild and is believed to be one of the largest green anacondas ever documented.
A clip from the series, which shows the Waorani hunters catching the snake, can be viewed below.
