Glow-In-The-Dark Plankton
Have you ever seen a field full of flickering fireflies? What about a video of glowing jellyfish or anglerfish in the deep sea? These animals aren’t the only glow-in-the-dark creatures on Earth. The most common ones, though, are much, much smaller.
Some plankton can glow in the dark. The word for this is “bioluminescence,” which comes from “bio,” meaning life, and “lumin,” meaning light. Most of these plankton glow blue, but a few can glow green, red, or orange.
