You might have seen this glowing water in Moana or Avatar, but it actually exists in real life. It's not magic or some sort of underwater light show. What you're actually seeing is called bioluminescence. It happens on beaches around the world, like Laguna Beach, Cocoa Beach, and the Indian River. It is emitted by tiny organisms called bioluminescent algae that live in the water. This algae contains a chemical called luciferin. When the water is disturbed or exposed to external pressure, the luciferin reacts with oxygen, turning chemical energy into light. And it’s actually meant to scare predators away. Inside the water, billions of tiny plankton live. When they feel threatened, they start glowing as a way to scare off any predators nearby.
