We were in Galveston, TX a few weeks ago for Mardi Gras and the manowar were everywhere one day, like 1/ft along the beach ranging from 1 inch to about 8 inches long. I had a run in with one as a kid, I've never forgotten it! We also saw several pieces of the cannonball fish, we had no clue what they were, the bubble part of them must have popped before we came up on them because we only saw the thick rubbery looking part-1st time to see those for us.
Last year at Seagrove we saw tons of the blue buttons a couple of different days, we didn't know what they were so we named them condom jellies!!!
