What is Bioluminescence?
Bioluminescence is a natural phenomenon where certain marine organisms emit light, creating a magical glow on the ocean surface at night. The primary contributors to this phenomenon are microscopic plankton called dinoflagellates, which shine due to a chemical reaction between the luciferase enzyme and luciferin compound in the presence of oxygen, producing a cold, blue-green light.

This captivating glow is not just limited to Chennai; it has been observed on other Indian shores, including Havelock Island in the Andamans, Mattu beach in Karnataka, and Bangaram Island in Lakshadweep. The phenomenon is particularly visible during warm weather and low-light conditions, usually in lagoons or near breakwaters.
Why Does Bioluminescence Occur?
The primary purpose of bioluminescence varies among marine creatures. It can be used to evade predators, attract prey, or even during mating. Apart from dinoflagellates, other sea organisms such as jellyfish, sponges, certain fish species, and worms also exhibit this magical glow.
In Chennai, the phenomenon occurs during warm weather when the plankton population peaks, and their 24-hour circadian cycle causes them to emit light, making the waves shimmer in low-light settings.
This awe-inspiring natural occurrence is a reminder of the ocean’s beauty and mystery, offering a rare opportunity to witness the wonders of marine life up close.
If you missed the bioluminescent waves in Chennai, you can still plan to visit other bioluminescent beaches across India and experience nature’s magic at its finest.
