Bioluminescence and Fluorescence in Animals

Maddie explores why various animals, including bacteria, mushrooms, and jellyfish, glow in the dark. This bioluminescence is similar to a glow stick's chemical reaction involving luciferin and luciferase. Most bioluminescent animals live in the ocean's dysphotic zone. On land, fireflies use light for mating, being highly efficient light producers. The reason for scorpion fluorescence remains a mystery, with theories suggesting it might attract insects or serve as a sunscreen. Research on nocturnal animals is facilitated by their fluorescence, aiding in population studies and behavior analysis.
