Bioluminescence in Gippsland Lakes, Australia -- The eerie blue glow is created by Noctiluca scintillans, a common marine dinoflagellate protist found worldwide in shallow coastal waters. As the dinoflagellates are disturbed by mechanical motion of the waves, they fire their lights. During blooms, waves literally glow icy blue as they crash onto the shore. I had the privilege of seeing this on Orpheus Island, Australia.
Bioluminescent bay @ Puerto Rico, you can go kayaking at night because it literally glows at night!
