I cut my after work ocean swim short yesterday after being hit big-time by Portuguese Man-Of-War. For those of you who've never gotten a direct hit by one, the pain for the first five minutes is INTENSE. My first experience came from encountering one with my thumb. It was like someone had slammed a hammer with all their might onto my thumb. Yes, really.
But at least all I had were the tendrils. A snorkeler came out of the water soon after I did, and he had the entire jellyfish still attached to him. Owie.
