We decided to dinghy over and check out how the set up was going for the stranded naked party the next day.  The kids did a little snorkeling.  The water near the beach is very shallow, about a foot deep.  As we were walking, Karon spotted something in the water she thought was a rope.  When she looked closer she saw the spots on it and realized it was some kind of eel or snake.  We were able to get pretty close to it and I took some pictures.  Soon it disappeared in a hole in the sand.  The sand here had a lot of these holes so I am sure there were many more where this one came from.  It had the body of a snake but the head of an eel.  I am not sure what it was.
