Mosquito Bay, Puerto Rico (2/8)

A biobay is a bay where the water literally glows. The bioluminescence of a bio bay is caused by single-celled microorganisms called dinoflagellates. These microorganisms glow briefly, usually in a blue-green color, whenever they are disturbed. This means that every splash and every movement in the water causes the dinoflagellates to light up in the water around you, giving the bay its distinctive glow.

As if that atmosphere isn’t romantic enough, it’s made all the cooler by the fact that you can’t actually photograph a biobay. It just doesn’t translate to film. Basically all of the photos online are edited, and they don’t come close to capturing what it’s really like. That means that you have to actually travel to a biobay to have this once-in-a-lifetime experience. What’s more romantic than that?
