From AP:

Steve Irwin, the hugely popular Australian television personality and conservationist known as the “Crocodile Hunter,” was killed Monday by a stingray while filming off the Great Barrier Reef. He was 44.

I liked watching the Crocodile Hunter, but can honestly say I thought it was only a matter of time before news like this broke. I think his brushes with danger is what made his shows so appealing.
