At the ocean depths not reached by sunlight, as many as 90% of life forms make their own light. They flash. They sparkle. They glow. Like the fireflies you remember chasing in your youth, they produce light by biofluorescence or bioluminescence.
Sometimes they reach the surface or live on land. Waves of phosphorescent algae crash on the shore and form the wakes of ships. This is as wondrous as a James Cameron sci-fi film… but it’s real.
