Steve Irwin

Irwin and his entire crew suspended operations to aid in the search. His team's divers searched with the rescue divers, and Irwin used his vessel to patrol the waters around the island where the incident occurred, as well as using his satellite communications system to call in a rescue plane. On the second day of the search, kayakers found one of the divers, Scott Jones, perched on a narrow rock ledge jutting out from the side of a cliff. Irwin and a crewmember escorted him to Irwin's boat. Jones did not recognise Irwin. The other lost diver, Katie Vrooman, was found dead by a search plane later the same day not far from Jones' location.

In 1997, while on a fishing trip on the coast of Queensland with his father, Irwin discovered a new species of turtle. Later given the honour of naming the newly discovered species, he named it Irwin's turtle (Elseya irwini) after his family. Another newly discovered Australian animal – a species of air-breathing land snail, Crikey steveirwini, was named after Irwin in 2009. Read Less

Irwin was in the area filming his own documentary, 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 Irwin was hosting when the ray suddenly turned and lashed out at him with the spine on its tail.

The events were caught on camera, and a copy of the footage was handed to the Queensland Police. In an interview with Time, marine documentary filmmaker and former spearfisherman Ben Cropp concluded that Irwin had accidentally boxed the ray in, causing it to attack: "It stopped and twisted and threw up its tail with the spike, and it caught him in the chest. It's a defensive thing. It's like being stabbed with a dirty dagger. It's a one-in-a-million thing. I have swum with many rays, and I have only had one do that to me." Read Less

However, the following day, when he first described the video to the media, he stated, "Steve came over the top of the ray and the tail came up, and spiked him here the chest, and he pulled it out and the next minute he's gone."

It is thought, in the absence of a coroner's report, that a combination of the toxins and the puncture wound from the spine caused Irwin to die of cardiac arrest, with most of the damage being inflicted by tears to arteries or other main blood vessels. A similar incident in Florida a month later, in which a man survived a stingray barb through the heart, suggested that Irwin's removing the barb might have caused or hastened his death.

Crew members aboard his boat called the emergency services in the nearest city of Cairns and administered CPR as they rushed the boat to the nearby Low Islets to meet an emergency rescue helicopter. However, despite the best efforts of Irwin's crew, medical staff pronounced him dead when they arrived a short time later. According to Dr Ed O'Loughlin, who treated Irwin, "it became clear fairly soon that he had non-survivable injuries. He had a penetrating injury to the left front of his chest. He had lost his pulse and wasn't breathing." Irwin's body was flown to a morgue in Cairns. His wife, Terri Irwin, who was on a walking tour in Cradle Mountain-Lake St Clair National Park in Tasmania at the time, returned via a private plane from Devonport to the Sunshine Coast with their two children.

The US feed of the Animal Planet cable television channel aired a special tribute to Irwin that started on Monday, 4 September. The tribute continued with the Animal Planet channel showing highlights of Irwin's more than 200 appearances on Discovery Network's shows. CNN showed a repeat of his 2004 interview on Larry King Live. Late-night talk show host Jay Leno—on whose show Irwin had appeared more than ten times—delivered a tribute describing Irwin as a great ambassador of Australia. There were also tributes on Live with Regis & Kelly and Barbara Walters' The View.

Hundreds of people visited Australia Zoo to pay tribute to the deceased entertainer and conservationist. The day after his death, the volume of people coming to pay their respects affected traffic so much that police reduced the speed limit near the zoo and told motorists to expect delays. BBC reported on 13 September that thousands of fans had been to Australia Zoo since Irwin's death, bringing flowers, candles, stuffed animals and messages of support. In the weeks after his death, Irwin's conservation foundation, Wildlife Warriors, reported that thousands of people from around the world were offering their support via donations to the conservation group.
