Bioluminescence is caused by Noctiluca scintillans, a type of phytoplankton that convert their chemical energy into light energy when washed ashore.
It is found in many marine organisms such as bacteria, algae, jellyfish, worms, crustaceans, sea stars, fish and sharks. According to marine experts, the phenomenon is an indicator of climate change and can have an impact on deep sea fishing.

Dr. Pravakar Mishra, a specialist in Coastal Processes and Shoreline Management Studies at National Centre for Coastal Research (NCCR), said the bioluminescence could have been caused by heavy rain and discharge of sewage into the ocean on Sunday night.
“NCCR has been monitoring beaches in Chennai for the past five years. This is the first time that we are noticing this type of plankton bloom”, said Dr. Mishra. “The phytoplankton burst could have occurred due to heavy rain and discharge of sewage into the ocean on Sunday. Factors such as pattern of the wind and the temperature of the ocean also determine the occurrence of bioluminiscent waves,” Mishra added.
