If you happen to be in Bermuda during a summer full moon, you may see a very surprising sight – Glow Worms!
Native to Bermuda, these bioluminescent worms usually live in tunnels under the sand, but during warmer months, they’ll suddenly all emerge together under the light of the full moon to mate. Scientists still aren’t totally sure how exactly they know it’s the full moon.
Being bioluminescent, their pale green glow comes from a chemical reaction inside their bodies. It’s known as a “cold” glow because nearly all of the energy from the reaction is used to generate light instead of heat.
Watch the video below to see one of these glowy little worms in action!
