Living things may produce and emit light; this phenomenon is known as bioluminescence. It demonstrates chemiluminescence. In addition to certain fungi, microorganisms, including some bioluminescent bacteria, and terrestrial arthropods like fireflies, a vast variety of marine vertebrates and invertebrates also exhibit bioluminescence. When symbiotic bacteria from the genus Vibrio generate light in some animals, it is called bacteriogenic light. In other species, however, the light is autogenic, meaning it is produced by the creatures themselves. A light-emitting molecule and an enzyme, often known as luciferin and luciferase, respectively, are involved in the main chemical process in bioluminescence. Since these terms are general, luciferins and luciferases are frequently identified by the species or group, for example, firefly luciferin. The enzyme catalyses the oxidation of the luciferin in every instance that has been described. Creatures can mimic other animals to attract prey or communicate to other members of their species to attract mates. They can also employ bioluminescence as a counter illumination camouflage technique. Genetic engineering and biological research in the laboratory using luciferase-based systems. In addition, a bioluminescent plant has been established, and researchers are looking at the potential use of bioluminescent systems for aesthetic and public lighting.
