Man O war

Tonight, we were walking the beach in Flagler Beach, Florida. A family walked over to us and asked "is this a jelly fish?". They had what looked like. Jelly fish on the end of a stick. It had washed ashore. We said yes, and they dropped it and placed the stick in the sand beside it to warn other beach goers. We watched it for a minute, and we noticed it was moving around. This thing wash huge, and definitely alive! We took this picture, and did a search for the type of jelly fish it was, which is when we realized it was a man o'war!!!
