What is bioluminescence?
Bioluminescence is a chemical reaction in an organism, triggered by motion. It is the main source of light in the natural marine environment, especially the deep sea.
For us humans the most common organisms emitting bioluminescence we observe are dinoflagellates - in Vieques of the 'Pyrodinum bahamenses' kind :). On the surface of the ocean bioluminescence can only be observed at night and with minimal light pollution. That's why it is a good idea to check the
moon schedule, if you plan to experience the biolumiscent bays in Vieques!!
Vieques has one of the brightest occurrences of bioluminescence in the Caribbean. Make sure you do not miss the mixing of luciferin and luciferase :) Better yet, jump in the water and get them going!
