Yep, a jellyfish the size of your fingernail can kill you. I saw a show about a guy that was diving and got stung. I don't remember the outcome. I assume he must have lived, but not sure. He was wearing a wetsuit. THe assumption was that there was a gap between the sleeves of the wetsuit and the gloves that he was wearing, and he got stung on that gap. And the assumption is that he was hit by an irukandji, because he didn't see it because the darn things are so small and practically invisible.
