DOCUMENTED PHENOMENA
A field atlas of living light.
Bioluminescence is light produced by living organisms. This editorial atlas introduces its roles without turning every mystery into certainty.
Recognition
Patterns of light may help animals identify or communicate with one another.
Attraction
A luminous point can draw attention in waters where visibility is scarce.
Defence
Some flashes startle, distract or redirect a nearby threat.
Camouflage
In the open ocean, making light can sometimes help a body disappear.
Human wonder
Science, photography and art translate living light into stories we can share.
