Following a crocodile attack on the team's cameraman, Ben Fogle and the rest of the expedition decide to continue their underwater crocodile studies. Nervously they approach the territory of a large female crocodile - Tutwana. Once underwater they find her immediately and Ben is astonished when she shows no interest in them whatsoever. It's a brilliant moment for the team who are allowed to study Tutwana's eyesight up close without any objection from this reptilian killer.
