Sunday #Plankton #Factoid 🦐🦠

Several news articles recently about #bioluminescence showing glowing waves crashing against beaches. Usually caused by #dinoflagellates, this #chemoluminescence reaction (luciferin with luciferase) is widespread throughout the water column by many organisms (fish, jellyfish, zooplankton, mollusks, bacteria...). Very common in the deep sea for communication, predation, and escape, and often due to bacterial #symbiosis. Most light is blue or green but can be red.
