Do sea turtles get barnacles? I was looking at a fresh water turtle today and noticed the algae growing on its shell. I think if I were a turtle algae on my shell would bother me, and I wondered why he wouldn't try to get it off. Then I realized I've never seen a photo of a sea turtle with barnacles, so I wonder what they do to keep the barnacles off, and if they even get them at all. It makes sense they might get them, but I don't know if it's common for sea turtles to have barnacles and clean them off somehow, or maybe there's some sort of PR bias against showing photos of them with barnacles.
