Global explorer/wildlife biologist Niall McCann tracks down the largest, fiercest animals in the world to learn more about their behavior and habitat. His conservation research takes him to the swamps of Venezuela to catch giant anacondas, into the jungles of Nepal to follow fearsome predators like the royal Bengal tiger, and to Australia's Northern Territory to wrestle with deadly saltwater crocodiles. McCann also studies human encounters with abnormally big or dangerous animals in the places he visits.
