I was diving with the kids who were off to the left swimming slowly along the reef. I topped a small coral rise and there in front of me floating above the sand… The scene was there for a few seconds, enough for me to pull up the camera and fire one frame. There was no second shot. They parted and the kids never saw this till I downloaded this to the computer. I’ve haven’t been around that much, but I don’t think anyone else has this.
