Bioluminescent bays are uncommon due to its delicate nature and surrounding ecological issues. The phenomenon of luminescence occurs irregularly in tropical warm waters around the world. Puerto Rico, luckily, is one of a few places that has three well-preserved bio bays. The healthiest two are located in Fajardo and Vieques. La Parguera has the least (compared to other two) number of dinoflagellate microorganisms that glow when water is agitated.
