Came upon a nurse shark today at Yucab which had a hook embedded in its mouth and some attached line. Nobody in our group had any line cutters. Kind souls may wish to keep an eye out for this thing and at least try and cut the trailing line. I couldn't really see how much there was as it was tucked under a ledge. On a better note, I saw a very, very young turtle (maybe 6 inches long) making his way along the reef. Reminded me of the movie "Finding Nemo".
