My Bucket List / Experience Goals
Visit A Bioluminescent Beach
Ticked off in 2020
What it is
Bioluminescent plankton glow blue when the water is disturbed.
How to do it
Kayak tours in Puerto Rico's Mosquito Bay are among the brightest.
Top tip
Go on a moonless night.
My experience
The stunning phenomenon of bio luminescent beaches is actually a chemical reaction that allows living creatures to produce light.
The glittering critters were dinoflagellates, a phytoplankton species found across the world’s oceans. These tiny organisms emit light to startle predators and, some scientists think, to draw the attention of other creatures that eat the original predators. In high concentrations, flashing dinoflagellates can make the water glow.
