The biochemical emission of light by living organisms, such as fireflies, deep-sea creatures, and certain fungi.
From Greek 'bios' (life) + Latin 'lumen' (light) + '-escence' (becoming). Life that literally MAKES its own light — no batteries required.
LIVING LIGHT! Fireflies, deep-sea anglerfish, glowing mushrooms, and ocean plankton all make their OWN light from chemistry! When you swim in bioluminescent water, every splash creates STARS! Life is magical! 🌊✨🦑
