@fact_cus: Why the Ocean Glows Blue at Night Ever seen the ocean glow bright blue when touched? It’s not an effect—it’s real nature at work. Tiny organisms called bioluminescent plankton emit light when disturbed, creating a glowing blue effect in the water. This happens due to a chemical reaction that acts as a defense mechanism to startle predators. While it’s meant for survival, for humans it looks absolutely magical. #ocean #bioluminescence #DidYouKnow #naturefacts #sciencefacts factshorts Disclaimer: This video is for informational purposes only.
