Sea Of Ardora On The Beach Of Carnota (a Coruña)

CARNOTA, A CORUÑA GALICIA, SPAI, SPAIN - AUGUST 07: View of the Sea of Ardora on the beach of Carnota, on August 7, 2024, in Carnota, A Coruña, Galicia, Spain. The Sea of Ardora is a natural phenomenon in which the sea water glows with a bluish hue in the darkness of the night. This spectacle is due to bioluminescent microorganisms, specifically the dinoflagellate Noctiluca Scintillans and other species of microalgae, where the organisms emit light as a result of internal chemical reactions, creating the characteristic luminous effect in the water. When there is a high density of microalgae and the water is agitated, this reaction that generates the blue glow occurs, a reaction similar to that which occurs in terrestrial fireflies.
