In what has turned out to be sad and shocking news, the man known as The Crocodile Hunter, Steve Irwin, was killed while filming an underwater documentary. While swimming in Batt Reef in north Queensland, Irwin was killed by a stingray barb that went through his chest (although, one doctor thinks he may have suffered from a form of cardiac arrest, as this type of stingray injury is extremely rare.) Steve Irwin was 44, and is survived by his wife Terri, and children Bob and Bindi.
