Some animals don’t just survive in the dark — they light it up. From deep-sea predators to insects on the forest floor, living organisms across the planet have evolved the ability to glow. This phenomenon, known as bioluminescence, has appeared independently dozens of times in nature. But why? In this episode, we break down how bioluminescence works at the molecular level. Special compounds like Luciferin react with enzymes called Luciferase to produce light — no electricity required. ---+ For all things Earth Month, check out our playlist: https://www.youtube.com/playlist?list=PLnNZYWyBGJ1F8ofFm4H9UTrHxqU8zngK4 👉 Donate to KQED, the public media station that makes Deep Look: https://donate.kqed.org/deeplook SIGN UP for Deep Look’s newsletter, Nature Unseen: https://bit.ly/NatureUnseenSignUp SUBSCRIBE: https://www.youtube.com/@KQEDDeepLook?sub_confirmation=1 ---+ Find a transcript on KQED Science: https://www.kqed.org/science/2000492/why-do-animals-glow-the-science-of-bioluminescence ---+ More great Deep Look episodes: Why Mammals Gave Up On Laying Eggs https://www.youtube.com/watch?v=ilpmpCEDK8A I Simulated Insect Vision and It Got WEIRD https://www.youtube.com/watch?v=5UCQoFO9dIk Can You Spot These Insane Camouflaged Animals? https://www.youtube.com/watch?v=Gpvc5ZX5B08 ---+ Thank you to our top Patreon supporters ($10+ per month)!
