Sept. 4, 2006: Though Steve Irwin wrestled countless crocodiles on his show “The Crocodile Hunter” and lived to tell about it, he was killed by a stingray's poisonous barb while filming a documentary called “Ocean's Deadliest.” Irwin's manager and producer, John Stainton, said the cameras were rolling when Irwin was hit, and the video shows him pulling the barb from his chest before dying. __
