News stories on his death made up a bulk of the top 15 most-linked stories, and top 12 most cited. The most common sentiment among bloggers? That they can't believe it was a stingray that got him in the end.
Irwin was stabbed in the chest by a stingray while filming the documentary "Ocean's Deadliest." The fatal attack was caught on camera, but there are currently no plans for the footage to be released.
Executives at the network that aired his exploits, the Discovery Channel, were shocked as well.
"I don't think we will ever get over the loss of Steve Irwin, a human being of enormous feeling and irrepressible enthusiasm and dedication to everything he touched," Judith McHale, chief operating officer-president of Discovery Communications, said in a statement.
To commemorate its slain star, Animal Planet will begin airing special programming this week chronicling the early stages of Irwin's crocodile career, with a best-of marathon to air on Sept. 10. The network has also unveiled plans to redub the garden space in front of its world headquarters in Silver Spring, Md., the "Steve Irwin Memorial Garden."
As for the stingrays, they're expecting business as usual. Stingray City tour guide Pat Kenney told CNN that despite Irwin's incident -- the third recorded stingray death in Australia -- all tours will run as scheduled.
"This is the first known death I've ever heard of. This is one of the rarest occurrences that you can possibly believe," Kenney said.
