Did you know that there are beaches that light blue in the night? Well yes, they say sea ​​of ​​stars and it is thanks to bioluminescence, biological phenomenon that consists in the production of light by some living beings. The word comes from the Greek (bios) meaning “life” and the Latin lumen meaning “light.” we’ll tell you where you can see a sea ​​of ​​stars on the beach.


These organisms that produce light use it as a defense mechanism, like camouflage, to attract prey, as communication or simply for the most obvious lighting function. Some examples are fireflies, jellyfish, squids, dinoflagellates and other marine organisms.

Where are they?

Some bioluminescent aquatic ecosystems are found in Puerto Rico (Laguna Grande, Mosquito Bay and La Parguera Bay), Maldives (Vaadhoo Beach), Mexico ( Manialtepec lagoon in Oaxaca) and San Diego (California). In these places they inhabit microorganisms able to emit light when they are disturbed by some movement.

The highest concentration of these organisms is in Mosquito Bay, Puerto Rico. Where the dinoflagellate inhabits Pyrodinium bahamense, responsible for this phenomenon.


These places are sometimes unconsciously exploited; buildings are not controlled near the beaches and lagoons, nor it is regulated the tourism that accesses wildly. This can lead to degradation of the ecosystem, Then the number of bioluminescent emitters decrease and thus the beauty of the natural phenomenon.


This colorful show that happens in these places is something out of the ordinary. It generates incredible sensations to all who visit it. It is highly recommended as a tourist circuit. For almost all cases are parts of the options of relaxation of foreign visitors to these places. In the mornings and afternoons they usually visit shopping centers, swimming pools, restaurants, historic buildings and other interesting places. At night enjoy the starfish on the beach; is the most logical option for nature lovers.
