bioluminescent bay (Vieques, Puerto Rico)

Bioluminescent bay in Vieques, Puerto Rico, is a natural wonder where tiny microorganisms called dinoflagellates emit blue-green light when disturbed. This creates a glowing effect in the water during nighttime, especially when boats or swimmers move through it. The bay's unique environment—calm, warm, and nutrient-rich—supports a high concentration of these microorganisms, making the glow particularly bright. This phenomenon is a result of natural chemical reactions within the dinoflagellates, providing a mesmerizing, luminous experience that highlights the delicate balance of this protected ecosystem.
