Bioluminescence is a highly evolved survival tool that works like nature’s own superpower. Marine organisms, such as sea sparkle, use light to stay safe in a dangerous ocean. Some creatures flash a bright light to startle and confuse hungry predators, giving themselves time to escape. Others use their glow like a “burglar alarm”. This flash illuminates an attacker, making them easy targets for even larger fish. Animals also use light to communicate with friends or hide their silhouettes from predators hunting below them. According to the National Geographic Society, this incredible ability evolved independently in many different species as a critical adaptation for finding food, attracting mates, and staying alive. 76% of ocean animals produce light. Furthermore, National Geographic-backed exploration, including the development of special “shark-eye” cameras, has revealed widespread biofluorescence and led to medical applications using these marine proteins.
