Vieques' Bioluminescent Bay
As the sun sets billions of Dinoflagellates put on an interactive light show in Vieques’ famed Mosquito Bay. Dinoflagellates are tiny one-celled organisms that glow brightly when moved. A natural defense mechanism, their nightime glow attracts fish that eat smaller organisms preventing them from feeding on the Dinoflagellates. Named the brightest bio bay in the world by the Guiness Book of World Records, Vieques' Bioluminescent Bay is truly magical and a once-in-a-lifetime experience!
Why is the light blue?
Blue and green light travel farther than other wavelengths in water. Most marine animals are adapted to see these colors of light.
Is it the same year round?
The dinoflagillates are abundant all year round, and "shine brightest on nights following bright sunny days*". They are also best viewed on the darkest nights when there is little to no visible moon in the sky.
