Marine bioluminescence is produced by an incredible range of organisms, from bacteria and single-celled protists to fish and squid.

 

Some especially interesting examples are:

  • A squid which changes the color of its luminescence to match moonlight and sunlight.

  • A fish with its own "night-vision" light.

  • Crustaceans which send out coded messages to their own species when it is time to mate.

 


New Section:
Guides to growing dinoflagellates in the home and the lab.

These pages include suggestions for experiments involving dinoflagellates, and information and links to other dinoflagellate pages.


 

Here is a partial list of bioluminescent organisms.

If an organism is listed here it means that at least one species in that group is luminescent, not that all such creatures make light.

This list is intended to give an idea of the diversity of bioluminescent creatures. It is not meant to be comprehensive, and there may be other luminous creatures which are not included here.
