Bioluminescent dinoflagellates (Lingulodinium polyedrum) lighting a breaking wave at midnight. The blue light is a result of a luciferase enzyme (like firefly luciferase, but the enzyme in L. polyedrum shares no similarity with that of the firefly enzyme). Under the right conditions, the dinoflagellates become so numerous that the water takes on a muddy reddish color (hence the name "Red Tide").
