Steve Irwin, known around the world as the crocodile hunter, was killed by a stingray more than seven years ago, off the Northeastern coast of Australia while diving with cameraman Justin Lyons.
"I had the camera on. I thought, 'This is going to be a great shot. It's going to be in the documentary for sure - fantastic.' And all of sudden (the stingray) propped on its front and started stabbing wildly with its tail," Lyons told Network 10's Daniel Sutton.
Irwin had made a career out of close encounters with dangerous animals and when he died, he was filming a documentary called "Oceans' Deadliest."
"It was only when I panned the camera back that I saw Steve standing in a huge pool of blood," said Lyons.
They got back in the boat and that's when Lyons saw the two inch wide gash over his friend's heart.
"They've got a venom on their barb, so I'm sure it was excruciatingly painful," he said. "He had an extraordinary threshold for pain, so I knew that when he was in pain it must have been painful."
