On September 4, 2006, Australian wildlife expert and TV personality Steve Irwin was tragically killed while filming an underwater documentary.
The famous zookeeper was notorious for seeking out face-to-face interactions with dangerous wild creatures, but his untimely death still left the world shocked.
While filming Ocean's Deadliest, Steve was unexpectedly attacked and killed by a stingray — a creature not known for being particularly aggressive or dangerous — when he was only 44 years old.
Steve gained global notoriety for his risky wildlife encounters and his enthusiasm about various creatures. He often encountered deadly and dangerous animals, many of which were usually endangered. He was known to commonly explore crocodiles in Australia's Outback and later traveled through the jungles of Asia and Africa.
While some criticized Steve for disturbing wildlife or indulging in showmanship, he was dedicated to preserving life's wild creatures. He claimed that his risk-taking style helped raise concern for threatened, but dangerous, animals and enabled viewers to appreciate their power, beauty and uniqueness.

In a new episode of the REELZ series Autopsy: The Last Hours Of..., airing Sunday, July 18, world renowned medical examiner and foresenic pathologist Dr. Michael Hunter investigates the science behind the freak accident that killed the beloved wildlife explorer — and how Steve's relentless need for adrenaline might have had something to do with it.
“Adrenaline has a pain-killing, analgesic effect, but it is also addictive," Dr. Hunter said on Steve's desire for the hormone. "Studies have shown how so-called ‘adrenaline junkies’ like extreme sports athletes, describe their cravings for dangerous activities in a similar way that a drug addict describes the overpowering urge to use substances."
"It lights up the same region in the brain as narcotic-based addictions. And like drug addicts, the more they do, the more desensitized they become. Their fear threshold increases, and this encourages them to take more risks," he continued in the episode.
