Q. Which city in India recently witnessed bioluminescent waves?
Answer: Chennai
Notes: Chennai recently witnessed bioluminescent waves, a natural phenomenon caused by marine organisms like dinoflagellates. These microscopic plankton emit light at night, visible on the ocean surface. Bioluminescence is common among many marine animals such as jellyfish, fish, and algae, used for evading predators, attracting prey, or mating. It occurs when the enzyme luciferase reacts with luciferin in the presence of oxygen. This phenomenon is often visible in warm weather and low light. Other beaches in India like Havelock Island, Mattu Beach, and Bangaram Island have also experienced it.
