What is Bioluminescence?
Bioluminescence is the emission of light created by a living organism. In the Salt River Bio Bay, you will experience the light-emitting phenomenon of the single-celled microorganisms called dinoflagellates. As the water is agitated by the passing of your transparent kayak, it will seem as if your entire boat is engulfed in a light glow, or depending on the conditions, a cloud of pixy dust, or a starry galaxy racing beneath you!
