Paddling with My Sweety

H wanted to get at least one more couples paddle in before the season ended, so we took advantage of the nice weather and day care to make it happen. We invited along good friends. She picked an area where we could do something interesting, but not too crazy - Wickford.
We paddled from Wilson Park to Rome Point and back under clear skies. It was unremarkable - if you can call a relaxing and enjoyable day on the water unremarkable.
One crazy thing we did encounter were these crazy crab-like larval things floating in the water. They were everywhere and covered the water in a thin layer of goo. The things would get stuck on my arms and hands as a paddled. It was creepy! I still have no clue what they were, so info in the comments would be a great help.
