10 Animals That Can Literally Glow in the Dark

7. The Ocean's Light Show: Bioluminescent Plankton

Bioluminescent plankton are tiny organisms that create stunning light displays in the ocean. When disturbed, these plankton emit a bright blue light, illuminating the water with a magical glow. This bioluminescence is a defense mechanism, startling predators and attracting larger animals that might prey on the plankton's attackers. The most famous bioluminescent plankton are dinoflagellates, which are responsible for the phenomenon known as "sea sparkle." These organisms are found in oceans worldwide, and their glowing displays can be seen from beaches and boats alike. This section will explore bioluminescent plankton's biology, their ecological roles, and the environmental factors that influence their light production.
