A special video edition of Photo Sunday!

Last month on our honeymoon, my wife and I went on a whale-watching tour in St. Lucia. We only saw one whale - at a distance, and he didn't let us get close enough for me to take any good pictures - but the dolphins were another story.

We encountered this school of dolphins off the southwest coast of the island. There must have been dozens of them, leaping out of the water on every side of our boat, and they seemed as fascinated by us as we were by them. They were beautiful, sleek and as fast as missiles, easily keeping up with the boat. We circled for about an hour to watch them, but I could have spent all day there without feeling a trace of boredom.

Since it was impossible to predict when or where they would jump, I decided to switch to video instead, and I'm pleased with the way it came out. I think it gives a sense of their speed and grace that would have been much more difficult to convey in a photograph. We should be cautious in ascribing human emotions to non-human species, but I feel comfortable saying, at least in this instance, that these dolphins followed us in a spirit of curiosity and play. In fact, I almost got a sense that they were showing off!
