Bioluminescence: How Living Creatures Create Light

  1. Bioluminescence is the ability of living organisms to produce their own light.
  2. It happens through a chemical reaction between luciferin (a pigment) and luciferase (an enzyme).
  3. Fireflies flash light to attract mates, one of the most familiar examples.
  4. Deep-sea creatures use glowing lures to hunt or scare away predators.
  5. Some squid and fish glow to camouflage themselves against faint ocean light above.
  6. The light produced is β€œcold light,” releasing little to no heat.
  7. Bioluminescence appears in bacteria, fungi, insects, and many marine animals.
  8. Certain glowing plankton make ocean waves sparkle when disturbed at night.
  9. Scientists study bioluminescence to develop medical imaging and bio-sensors.
  10. Nature’s living lights show how evolution uses chemistry for survival and communication.
