• A group of students witnessed phenomenon of bioluminescence along the coast of Visakhapatnam recently.

About Bioluminescence

• Bioluminescence occurs due to the presence of some marine planktons called dinoflagellates that produce light when the water is disturbed.
• These planktons emit light on the ocean surface at night.
• Many marine creatures like sponges, jellyfish, worms, species of fish, anthropods, echinoderms and unicellular alga exhibit bioluminescence to either evade predators, attract prey or during mating.
• In Visakhapanam, this phenomenon is most likely the result of an algal bloom of the dinoflagellate species of noctiluca and ceratium.
• This occurs when the luciferase enzyme reacts with luciferin compound in the presence of oxygen to produce a cold light.
• The dinoflagellates follow a circadian cycle (24-hour cycle) and as a result this phenomenon occurs during the night which is visible in low light conditions.
• This unique phenomenon has been visible in some other beaches in India including Havelock Island in the Andamans, Thiruvanmiyur beach in Chennai, Mattu beach in Karnataka and Bangaram Island in Lakshadweep.
