Glowing Beach or Bioluminescent Bay (Bahía Bioluminiscente)

The ocean can glow and glitter like the stars in the sky than ks to a natural chemical process known as bioluminescence, which allows living things to produce light in their body.

In all over the world, there are some most wonderful, glowing, mysterious and interesting beaches that gleam neon blue during the evening. This natural miracle is brought about by phytoplankton (a kind of microalgae that coast at the outside of the seawater).

Glowing Beach Mosquito Bay, Puerto Rico

Mosquito Bay, better known as Bioluminescent Bay, is a tranquil, warm, shallow bay on the southern shore of the Puerto Rico island of Vieques. The bay is world famous for its extreme bioluminescence, declared as the brightest in the world.

Puerto Mosquito (Mosquito Bay) is located on the southern shore of the island of Vieques, one of the islands of Puerto Rico.  This bay is often referred to as “magical”, those blessed with the opportunity to experience it always agree.  The bioluminescent bay in Vieques was officially declared the brightest in the world by Guinness Book of World Records in 2008.  Hurricane Maria caused much destruction on the island, it sadly disrupted the delicate balance of the bay, the beloved Mosquito Bay went dark.  To everyone’s surprise the bioluminescent bay not only recovered, but it is also brighter than it ever was in the past.

Tiny sources of light

Bioluminescence doesn’t refer strictly to the phenomenon as experienced in the water—rather, it’s an umbrella term for the production of light in living organisms. You’ve already seen a form of this unique capability in action if you’ve ever caught fireflies.

When bioluminescence occurs in the water, it’s usually the result of single-celled organisms like algae or plankton. The organisms can use their light as a defense mechanism, working to attract larger predators that can protect the tiny organisms from smaller animals. (For us, however, it’s just a breathtaking visual treat!)

Go With the Glow!! Is it Magic?

No, it’s not magic. With each paddle stroke, the girls stir up millions of tiny dinoflagellates (dy-no-FLAH-juh-luhts). When stirred at night, these plantlike life-forms glow beautifully. Each gallon of Mosquito Bay water holds some 750,000 dinoflagellates. Their combined light creates spectacular evening shows.

On the island of Vieques off the coast of Puerto Rico, Mosquito Bay’s dinoflagellates give off their bioluminescent (by-oh-loo-mih-NESS-ent) light from dusk until dawn. “In other parts of the world, bioluminescence is seasonal,” explains Sharon Grasso, a tour guide on Vieques. “But here, the water glows brightly year-round.”

Each night Grasso shows off the natural beauty of the bay. Passengers stare in awe as the tour boat leaves a glittering trail. They dip their hands in the water, leaving greenish-blue trails of their own.

Mosquito Bay’s displays are threatened, however. Bright artificial light from nearby developments can outshine the natural glow. Pollution, destruction of mangrove trees, dredging, land development, and overuse of the bay’s water can kill the fragile dinoflagellates. “We can’t let the lights go out,” says Grasso. “The magic of Mosquito Bay should live on forever.”
