Phosphorescent Bays

My husband and I are currently traveling in Puerto Rico.  I desperately want to go zip-lining in the rainforest; he wants to show me the phosphorescent bays (also called bioluminescent bays).  We may not make it there this trip, but I have spent some time reading about them.  Holy amaz-a-balls.  They are gorgeous!

The protist dinoflagellate lives in the bays and upon a drop in pH (more easily defined on tours as "agitation of the waters") a molecule binds to a protein in the organism and emits a blue light.  These little creatures can use this to scare their predators - very cool.  For humans, the mechanism is beautiful to watch. 

A few of these bays exist in Puerto Rico and are really popular destination spots.  You can read more about them here:
