What is the Pyrodinium bahamense ?
This microalgae is a type of dinoflagellate , a microscopic marine organism that belongs to the plankton. Its name combines the Greek words pyro (fire) and dinium (whirlpool), due to its ability to glow, making it visible in the dark. It is native to tropical and subtropical areas. In Puerto Rico, it is very present and abundant in coastal bays and lagoons. And when there is little light pollution, such as the famous Puerto Mosquito Bay in Vieques , it produces magical nighttime spectacles. Other places where it can be seen are in Parguera, in Lajas, and in Laguna Grande, in Fajardo.
Why is it so special?
He Pyrodinium bahamense is famous for its Bioluminescence : When water is agitated, it emits flashes of blue light thanks to a cellular chemical reaction. This phenomenon, which turns waves, fish wakes, or raindrops into aquatic shooting stars, attracts visitors from around the world. Furthermore, this organism plays a vital ecological role: it forms part of the base of the food chain and helps maintain nutrient balance in marine ecosystems. It is, in turn, an unquestionable indicator of environmental health: its presence indicates healthy waters, as it is sensitive to changes in salinity and pollution.
Puerto Rican and Caribbean Treasure
In Puerto Rico, our bioluminescent bays are globally recognized natural gems. The one on Vieques, considered the brightest in the world, is a source of pride that reflects the richness of our biodiversity. These places are not only a spectacle, but also living laboratories for studying species' adaptation to fragile environments. However, they require protection: pollution, excessive coastal development, and even our excessive presence threaten their survival.
A show that unites us
He Pyrodinium bahamense It reminds us that nature is art and science in motion. For Puerto Ricans, its glimmering light is part of our Caribbean identity, a gift that connects local communities, tourists, and scientists. Preserving it means caring for our coasts, reducing waste, and supporting responsible tourism practices, such as kayaking tours that avoid damaging their habitat. And this very respectful tourism model has the power to sustain communities in our towns.
