Jellyfish glowing in dark

Bioluminescent jellyfish emit their own light in dark waters, a rare and fascinating natural phenomenon.

About this subject

Bioluminescent jellyfish are marine organisms capable of producing their own light, a process called bioluminescence. This occurs when a chemical reaction within the jellyfish's body results in the emission of light. Bioluminescence is used to attract prey, communicate with other jellyfish, and defend against predators. Jellyfish are found in oceans worldwide, but are more common in warm and tropical waters. The ability to produce light is an important adaptation for survival in low-light environments.
