Another shot from St. John...

That was the first thing I thought when I first saw this thing coming at me out of the corner of my eye. About six feet long and coming right at me... YIKES! Then I realized it was just a nurse shark. I was in the middle of a survey so it took me a minute to get my camera up and snap the picture. So you see it swimming away from me and the perspective makes it look smaller than it really is.
