Light shapes life in ways most of us never notice.

Duke biologist Sönke Johnsen takes us beneath the ocean's surface to explore a hidden world where animals use light to survive, communicate, and disappear in plain sight. Through stunning images captured by Johnsen and his students, discover how marine organisms have evolved remarkable strategies involving transparency, bioluminescence, and vision—and why studying these mysteries matters for science, technology, and our understanding of the natural world.

After all, nature has been writing this language for millions of years. We're just beginning to learn how to read it.
