What Is Bioluminescence?

Bioluminescence is a natural process where living organisms produce light through a chemical reaction inside their bodies. This glow is often called “cold light” because it gives off almost no heat. It is most commonly seen in marine life, especially in microscopic organisms called plankton that float near the surface of the water. When these tiny creatures are disturbed by waves, fish, or even a splash, they create a beautiful glow that lights up the sea. This is what makes bioluminescent beaches so magical to witness in person.

The glow is most visible at night when the surroundings are dark, allowing the light to shine more brightly. On calm nights, the movement of the water causes the plankton to sparkle, creating an unforgettable sight. Many people travel from different places to find glowing beaches at night where they can watch the ocean light up with blue and green hues. The brightness often depends on the temperature, tides, and moonlight, which is why visiting during darker nights can make the experience even more breathtaking.
