Bioluminescence is the natural emission of light produced through a chemical reaction between the compound luciferin and the catalytic enzyme luciferase. First isolated in the late nineteenth century by French scientist Raphaël Dubois, this biological phenomenon is most prominent in marine environments, where sunlight is absorbed within the first 650 feet (200 meters) of the water column. In the ocean, roughly three-quarters of pelagic organisms, including jellyfish, squid, worms, and deep-sea fish, generate their own light. Marine species rely on bioluminescent adaptations across diverse…
