Dr. Brady Barr, a reptile specialist with the National Geographic TV channel, needed to get close enough to Nile crocodiles in Tanzania (length: up to 20 feet) to attach data monitors to their tails and decided to dress up as a croc and crawl to them. With a crocodile suit, a prosthetic head and a metal cage (and hippopotamus dung to mask his human scent), he was able to apply tags, with video to prove it (according to a June report in London's Daily Mail), with the scariest moment coming not from crocodiles but when a hippo wandered by, attracted by the dung scent.
