Invisible Nature: The Glowing Squid

The Hawaiian bobtail squid can cruise above its prey without casting a shadow—even on a moonlight night—thanks to its relationship with a bacterial partner.

This video was contributed by Annette Heist to bioGraphic, a magazine powered by the California Academy of Sciences to showcase both the wonder of nature and the most promising approaches to sustaining life on Earth.
