Juvenile box jellyfish. Too tiny to see...
When you get out of the water and dry off they sting you as they die. There is no obvious stinging feeling. The rash shows up later. The rash can also appear around the neck seal area of the wetsuit. People who get into the jellies while they are swimming can get them inside their suits. Later, when they get back to the room and take the suit off they have a rash all over their private areas.
If the suit isn't washed thoroughly, a person can be stung months later when they wear the same suit.
Just rub cortizone cream on it for a few days and it will go away.
