Australia's Amazing Bioluminescent Lake (Also Bioluminescent Bay in Puerto Rico). An unusually high concentration of Noctiluca scintillans, a bioluminescent microorganism, turned the water a bright, glowing, ethereal blue.
Oooo, you're the best friend that I ever had ~ I've been with you such a long time ~ You're my sunshine, and I want you to know, That my feelings are true ~ I really love you! Oh you're my best friend! (Song lyrics by Queen)
