Bioluminescence: Glowing Reactions in Nature

Bioluminescence is light produced by living organisms through chemical reactions.
The glow comes from luciferin reacting with oxygen, catalyzed by luciferase.
Fireflies use bioluminescence to attract mates and communicate.
Deep-sea creatures glow to lure prey, camouflage, or scare predators.
Some fungi emit light, creating eerie glows in forests at night.
The reaction is highly efficient—nearly all energy is released as light, not heat.
Bioluminescence can be green, blue, red, or yellow, depending on the organism.
Marine bioluminescence is so widespread that much of the ocean glows at night.
Scientists study bioluminescence for medical imaging and bio-sensing technologies.
It shows how chemistry and evolution work together to create natural wonder.
