There is a video that was never released of his death. The claim was that the sting ray hit his heart directly, which makes sense. Sting rays are very easy to agitate accidentally, sort of like a bee. He got really unlucky even if he were annoying an animal.

Hate the pointless narrative that he was bad for wildlife. Most American millennials love nature because of Steve. He is why we like the aussie accent in bluey imo.
