What a terrible loss. I loved watching his shows on TV. My heart goes out to his family. SYDNEY -- World-renowned "crocodile hunter" and television environmentalist Steve Irwin has died following a stingray attack in northeastern Australia, local government sources said Monday. Irwin, 44, known for his enthusiastic approach to even the deadliest of wildlife, was killed when a stingray barb punctured his chest during the filming and underwater documentary, the sources quoted by the Australian Associated Press said. The larger-than-life Irwin, dubbed "The Crocodile Hunter" after the nature documentary series he hosted, was filming off the coast of Port Douglas in the state of Queensland when the accident took place.
