FAQs

1. Which beach is renowned for having the most intense bioluminescence?
Mosquito Bay in Puerto Rico is renowned for its exceptional bioluminescence, making it the brightest in the world according to Guinness World Records. Located on the southern coast of Vieques, just off the east coast of mainland Puerto Rico, this narrow inlet surrounded by mangroves forms a dolphin-shaped bay, creating a protected environment where bioluminescence thrives.

2. Where can you see glowing waves at night?
At Hermosa Beach in California, you can observe the ocean waves glowing at night. This phenomenon is caused by microscopic phytoplankton known as Lingulodinium polyhedra, which emit blue light through a molecule called luciferin. This natural occurrence gives the ocean a mesmerizing, magical glow during the night.

3. What are the locations of the five bioluminescent bays worldwide?
