Normally you can't see much of dolphins at night.  The odd snort and splash are the only clues that there are dolphins playing around the boat.  Last night was different.
The Indian Ocean is noted for its bright phosphorescence.  It is the brightest we have seen so far, certainly.  The usual "star drive" that trails behind each hull has turned milky, with the phosphorescence from tiny animals making two long milky streaks behind us that are dotted with bright flashes from the bigger jellyfish.
Imagine what happens when a dolphin comes to play around the hulls.  You still can't see the dolphin itself, what you can see is an envelope of phosphorescence around a dolphin shaped hole, with a long streamer stretching out in the wake of each dolphin.  As the glittering dolphin shapes dart around, so their streaming light trails twist and turn around each other.  It is a truly magical sight.  It is another of those unexpected scenes of nature that we have encountered on our trip. 
Our only regret is that, while the phosphorescence seems bright, there is not enough light to capture the experience on photo or video.  You will just have to use your imagination.
