"I spent many years at sea, and one of the most enjoyable aspects was surface cruising late in a moonless night.  After 5 or 10 minutes away from lights your eyes become accustomed to the extreme darkness, and the bio-luminescence bursts into blue-green lava in the shock of the bow wave.  Eventually, a sailor can see the dolphins deep in the water as they excite the plankton into lighting up around them as they make trails in the sea.
