"Americans are most interested in natural phenomena, like chasing the Northern Lights, witnessing synchronized fireflies in Tennessee, or [seeing] bioluminescent plankton in Florida," said the spokesperson.
In Vero Beach, Florida, during the summer months, visitors can see bioluminescent waters glow brightly.
The light is due to a type of chemiluminescence in which there's a chemical reaction within a living organism, according to National Geographic.
