It is known, however, that fish can create streaks of light from pressure waves. NatSciDemo decided to see if we could create something that they thought looked like underwater lightning by using a trough of sea water containing dinoflagellates. Dinoflagellates are single celled organisms that photosynthesize during the day and have flagella attached. At night, when a pressure disturbance hits them, they emit light.

NatSciDemos pulled a segmented lure (Rapella is the manufacturer) through a tank filled with dinoflagellates in their night-time phase to see if it produced a result resembling 'underwater lightning'.
