There once was a South African guy on youtube who would roam Africa looking for poisonous snakes to photograph. In one of his videos he was bitten and you could see him recoil and say “guys,I’ve been bitten”. IIRC his name was Steve Austin.
Another herp filmed his own death. Reached into a bag in New Guinea? Indonesia? dunno....hoping to find some banded water snake and instead got a small fang bite from a banded krait. He talked his crew through life saving measures waiting for helo that couldn’t break through the weather.
