Sad news today that Australia's Steve Irwin, the quirky Australian naturalist who won worldwide acclaim, was killed by a stingray barb through the chest on Monday while diving off Australia's northeast coast.

Steve was hit by a stingray in the chest.He probably died from a cardiac arrest from the injury.He was 44.

Irwin won a global following for his dare-devil antics but also triggered outrage in 2004 by holding his then one-month-old baby while feeding a snapping crocodile at his Australian zoo.

He made almost 50 of his "Crocodile Hunter" documentaries which appeared on cable TV channel Animal Planet and won a worldwide audience.

May he rest in peace.
