Jellyfish glowing in dark

Bioluminescent jellyfish emit light in the dark, a rare and fascinating natural phenomenon.

About this subject

Bioluminescent jellyfish are marine creatures that have the ability to produce light. This occurs through an internal chemical reaction involving the molecule luciferin and the enzyme luciferase. The light produced is used to attract prey, communicate with other jellyfish, and defend against predators. Jellyfish are found in oceans all over the world, but are more common in warm and tropical waters. Bioluminescence is an example of the incredible diversity of adaptations that marine organisms have developed to survive and thrive in hostile environments.
