Didier Noirot and I have just got back from a very intriguing trip to the Okavango Delta in Botswana, where we succeeded in diving with large Nile crocodiles and documenting these extraordinary lizards underwater. I am going to write up a full expedition report when I get the chance, but can report that initially it was one of the most terrifying experiences of my life - those iconic images of huge crocs lunging out the water and taking down huge animals are not easy to push to the back of one’s minds when you get into the water with your first big one. Below are some screen grabs from the video sequences we shot for potential ‘Behind The Scenes’ use - that’s Didier with his Sony 900 in the Subspace housing.
