During a session last year in the Delmarva Area, I noticed a cool looking buoy with a length of rope dangling off of it. I decided to take it home so paddled over to it and grabbed the rope to tow it to shore. Immediately My upper body was covered with must have been a least a thousand small crustaceans (Amphipods) that made my skin crawl. I let go, rolled off the board and swam under water as far as I could and they released. Very Spooky but harmless.
