What Is The Beautiful 'Blue Tide' Spotted Along Juhu, Ratnagiri Beaches And Why It Is Dangerous

The tide that produces bioluminescence made an appearance on Tuesday night on Juhu beach in Mumbai and Devgad beach in Sindhudurg along Maharashtra’s coastline.  The spectacle occurs when phytoplankton, commonly known as dinoflagellates, produce light through chemical reactions in proteins. Waves disturb these unicellular microorganisms and make them release blue light.

During this period all the animals (molluscs, fish, etc.) that feed on dinoflagellates also become toxic due to the accumulation of high amounts of toxins from dinoflagellates.
