About this guide
Living Light is a small, independent guide to bioluminescence – made for anyone who has ever seen a firefly and wondered how it works.
What we are about
Bioluminescence is one of nature's most beautiful tricks, and one of its most useful. We want to make it easy to understand, easy to share and easy to go and see for yourself – responsibly.
We stick to well-established science. Where scientists are still debating something, like the exact purpose of a glow, we say so with words like "may", "thought to" or "one idea is".
Where our information comes from
Our content is drawn from ocean research institutes, national parks, tourism boards and peer-reviewed studies. Every page was fact-checked in October 2026, and the sources page lists the pages we used, grouped by page. If you spot an error, please let us know and we will fix it.
About the artwork
Every illustration on this site, including our jellyfish logo, is original artwork created for Living Light. The illustrations are decorative, so screen readers skip them – all the information is in the text.
Accessibility
Living Light is built to work with a mouse, keyboard, screen reader, voice control or magnifier, the same as the rest of Life's Uncertain. The illustrations are decorative and the glow animations switch off if your device asks for reduced motion. Read the full Accessibility Statement, and if anything is hard to use, please tell me.
