What is bioluminescence?
The breathtaking phenomenon of blue waves, known as 'bioluminescence' is caused by bioluminescent phytoplankton, specifically Noctiluca Scintillans, also known as "sea sparkle." It is a captivating natural phenomenon where chemical reactions within ocean-dwelling organisms produce mesmerising light displays.
These tiny organisms emit light when disturbed, typically due to natural factors like tidal movements, ocean currents, storms, or changes in water temperature and salinity. Environmental factors, including nutrient-rich waters, algal blooms, and human activities like pollution or dredging, can also contribute to bioluminescence.
This adaptive trait is shared among diverse marine species including fish, bacteria, and jellyfish.

''Spotted bioluminescence in Thiruvanmiyur beach. Was such a brilliant thing to witness. The last time we saw this was in 2019,'' commented another user.
''There are countless joys to living near the ocean, but today we added one more - bioluminescence on our beach! Message appeared on neighborhood WhatsApp group and we trooped down. It was truly magical to witness,'' a third said.
''Chennai's coastline is putting on a magical show! Witness the stunning #Bioluminescence as tiny organisms light up the sea at night. This rare natural phenomenon is turning our beaches into a glowing wonderland. Have you seen it yet?'' wrote a fourth.
