photos by mike roberts, masa ushioda, peter liu and doug perrine of green sea turtles being cleaned by yellow tangs, goldring surgeonfish and saddle wrasse. by feeding on the algea and parasites which grow on the turtle shells, the fish not only keep them clean, but reduce drag, helping the turtles to swim faster.
