Scary, currents drag you away from your dive site, you spend hours in the water, you manage to get yourselves to the last island before currents take you out into thousands of miles of empty ocean and then you come face to face with a dragon! Not a good day!

I checked the DAN diving medicine book, plenty about jellyfish stings, fire corals, venomous fish and snakes, but couldn't find much related to a Komodo Dragon bite. Sounds like pelting with rocks and sticks worked pretty well, so I'll use that if I'm ever faced with that problem.
