Nurse sharks are like the puppies of the deep. They follow divers over the coral out of curiosity and the possibility of a free meal. These sharks will cruise around and among the divers and will often come right up to them. It's hard to resist giving them a little pat or a stroke as they swim past. This young diver did just that, scratching the young shark on the head and back. The little fellow stayed with the divers for an hour as they explored the reef.
