Only time I was in the ocean with jelly fish was when my family went to FL for Christmas break. I was about 15 at the time, JAWS had just come out, my boyfriend and I had just seen it before our trip. Man of War jelly fish were on the beaches, being washed up there were hundreds of them, so the beach was closed. When it opened up, there were still signs of the jelly fish, warning you about them, we didn't know much about them, jumped right into the water. Mind you, there are 6 siblings in my family. When my baby sister started screaming about an hour later, I ran to the rescue. She was in the shallow water, down on her belly, and I thought of nothing else than a damn shark was trying to get her! I panicked, grabbed her by the arms and literally drug her onto the shore. I thought the shark was pulling at her, but it was the undertow. I picked her up and carried her farther away from the water, pumped cause I thought I was going to see blood on her legs! The life guard came running with kleenex and I think maybe alcohol. He very gently started pulling the tentacles off her legs. That sucker must have had 6' long tentacles, and she was one sick little girl that night. I was so scared from the experience, I didn't want to go back into the ocean the rest of the trip. LOL We were all swimmers, all swam on swim teams, competed, etc., so when she was screaming, what was an older sister to think, but the worst! Darn movie! I don't think I would have reacted the same had I not just seen that movie, and it scared the bejeebers out of me, too!
