Steve Backshall is headed for the waterways of South Africa’s Ndumo Game Reserve, home to the third largest population of Niles crocodiles. Over two episodes he takes us deep into their world to uncover how they have survived for millions of years and find out just what makes them such lethal predators. Steve is joined by a team of crocodile scientists and learns there is far more to these cold bloodied killers than first thought. He comes face to face with man-eaters and monster crocs and finds out how one of nature’s greatest survivors is adapting.
