These tiny, glowing specks in a dark room are actually living bacteria that have a special ability to produce their own light, like tiny living flashlights. This natural phenomenon is called bioluminescence.
They glow to attract mates, while others use their light to lure prey or distract predators. In the case of the Vibrio fischeri bacteria, found in the organs of marine animals like squid and fish, they produce light to camouflage themselves from predators by matching the ambient light around them, making them less visible in the water. So, these bacteria use bioluminescence as a survival strategy in their natural environments.
In bioluminescence, certain organisms, like bacteria, have special molecules inside them that react with oxygen to produce light. These molecules are called luciferin and luciferase. When the luciferin combines with oxygen in the presence of enzyme luciferase, it creates a chemical reaction that emits light.
The above bacteria came from squid ink pouch and skin region
