My vote is a wasp also or possibly a comb jelly. Typically you'll see wasps at night in shallow water and they are attracted to lights, but they can be out and about in the day. Everyone has a different reaction to these types of marine injuries, how do hold up against bees, ants etc.? Think about carrying a first aid kit that will help you handle this if it ever happens again
As for the skin, forget it and move on up to a 3mil, I've seen people get stung, poked etc, right through a lycra "skin"
