Aurelia aurita washed up

I saw at least 50 washed up at Lauderdale by the Sea, FL in a half mile walk just north of the pier at Commercial Blvd. This was one of the largest, as shot next to a child's sand toy that was about 5" in diameter. I washed the sand off a bit so the bright red gonads (I think - I am not a scientist, but looked up info on the web) would be visible. Others varied in size from around 5 inches and up. They were in great condition at this point. I picked this up to look at it underneath - it was smooth. I didn't see any tentacles at the edges. There was no sting.
