Over all my years of diving, two turtles in particular stand out. Raja and Robert. They were big beautiful loggerheads, and I came to know them very well. I knew Robert for 16 years. I would know when he would be here, and I'd visit him daily. He used to love to have his shell cleaned. The barnacles are a large anoyance to the turtles, and clearly slow them down. When I'd begin cleaning off the barnacles, Roger would just lie there with a big smile on his face, and you could feel his contentment.

Many years ago I attended a Turtle symposium, where a noted scientist was telling everyone that sea turtles could hold their breath for about 20 to 30 minutes.
