Steve Irwin, the Australian conservationist turned TV personality, died Monday while filming off the coast of Australia.
The 44 year-old "Crocodile Hunter" was filming off the Great Barrier Reef when he swam too close to a stingray. Witnesses say the animal's barbed tail struck Irwin through his chest and into his heart.
Experts say it was a freak accident. Friends say Steve Irwin died doing what he loved.
Irwin was known for his boundless enthusiasm, as well as his tendency to get up close and personal with wildlife.
