As hard as it is to believe the crocodile hunter has died because of a freak sting ray accident. Although he was bit wonkey he had a certain charm to him and his love of animals was apparent. The guy hugged croc's and he dies to a sting ray, that's like me dying while making a volcano with baking soda and vinegar. Anyways what follows is the wikipedia entry for those people who are interest in what happened.
"Shortly after 11:00am local time
on 4 September 2006
, Irwin was fatally pierced in the chest by a short-tail stingray
barb while diving in Queensland
's Batt Reef
, which is part of the Great Barrier Reef
. The events were caught on camera
and the footage is now in the possession of Queensland Police.
Irwin was in the area filming his own documentary, to be called The Ocean's Deadliest, but weather had stalled filming. Irwin decided to take the opportunity to film some shallow water shots for a segment in the television program
his daughter Bindi was hosting,
when, according to his friend and colleague John Stainton
, he swam too close to one of the animals. "He came on top of the stingray and the stingray's barb went up and into his chest and put a hole into his heart," said Stainton, who was on board Irwin's boat at the time.
After reviewing the footage of the incident and speaking to the cameraman who recorded it, marine documentary filmmaker and fisherman Ben Cropp
speculated that the stingray
"felt threatened because Steve was alongside and there was the cameraman ahead..."
In such a case, the stingray responds by automatically flexing the serrated barb on its tail, which is up to 25 centimeters (roughly 10 inches) in length.
"He came over the top of a stingray that was buried in the sand, and the barb came up and hit him in the chest," Stainton said. Wildlife documentary maker Ben Cropp
, citing a colleague who saw footage of the attack, told Time.com that Irwin had accidentally boxed the animal in. "It stopped and twisted and threw up its tail with the spike, and it caught him in the chest," said Ben Cropp
. "It's a defensive thing. It's like being stabbed with a dirty dagger." The Bull Ray
that stung Irwin was "a one-in-a-million thing," Cropp told Time magazine
. "I have swum with many rays, and I have only had one do that to me."
In this case, the motion struck Irwin's chest and pierced his heart.
This was only the third known fatality in Australian history from a stingray attack, and only 17 worldwide fatalities have taken place since 1996.
Crewmembers aboard his boat called emergency services in the nearest city of Cairns
and administered CPR
as they rushed the boat to nearby Low Isle to meet a rescue helicopter. Medical staff pronounced Irwin dead when they arrived a short time later. 
The barb lodged in his chest and the toxins of the barb caused Irwin to die of cardiac arrest
The Queensland Police Service
notified his family and released a statement for the media concerning his death.
News of his death prompted a public outpouring expressing shock and loss. Several Australian news websites went down because of high web traffic
and talk-back radio experienced a high volume of callers expressing their grief,
commemorating his passion and exuberance. Australian Prime Minister John Howard
, among many other politicians, expressed his "shock and distress" at the death, saying that "Australia has lost a wonderful and colourful son."
Irwin's body was flown to a morgue in Cairns
, where stunned family and friends were gathering on Monday night. His wife Terri was informed of her husband's death while on a walking tour in the Cradle Mountain-Lake St Clair National Park
, and returned via private plane from Devonport
to the Sunshine Coast
with their two children.
