Some shots at "Turtle Canyon":

As soon as I got in the water, the turtle below swam right underneath me. I was sorry to see that it had a really large fish hook pierced through its front left flipper.

Below is a series of shots of two turtles that came over towards me and then got into some interesting interactions with each other. I thought I had got some really nice shots at the time but for some reason I haven't figured out, the shots are out of focus. These turtles were moving quite quickly and it may be that the shutter speed was just too slow?!?

The pair above got quite close to me at times during their "dance" and it was exciting to be in the proximity of two large adults who were behaving in a manner I have not seen before. It was kind of like underwater wrestling. I suspect it might have been some form of courting but that's just a guess. They moved off and I was distracted by some other turtles. There are a lot of turtles on this reef and some are quite large!

I spotted a turtle I think of as "SharkBite" today. I have seen it other times visiting. One of these days I may be able to get close enough for a decent shot:
