The famous group of islands are known for being a heaven on Earth. But Vaadhoo Island has a lot of surprises, that are revealed at night.

This phenomena has been called the “Sea of Stars” due to its glowing blue waves. It’s definitely a fantasy-like experience but before you roll over in search for that specific beach in Vaadhoo to see the so-called Sea of Stars, better know more about the beautiful little creatures that cause this unbelievable glowing effect.

The mesmerizing shining water looks like a mirror, that reflects the sparkling stars above. However, the secret is this: phytoplankton – the marine microbes – are bioluminescent and emanate the blue glow. The species create the most romantic natural lighting in the world.


This phenomenon is caused by a natural chemical reaction known as bioluminescence, which occurs when a microorganism in the water is disturbed by oxygen. These microorganisms or marine microbes are called phytoplankton and there are a variety of its species that create bioluminescence seen in different parts of the world.

One of the most common phytoplankton that cause marine bioluminescence are known as dinoflagellates. Although dinoflagellates have this blue glow, it doesn’t mean that they’re friendly at all. Some dinoflagellatesproduce toxins harmful to fish, humans, and other creatures. The blue light is believed to be some sort of a defense for these marine organisms. Predators which eat the glowing dinoflagellates may attract bigger predators because the phytoplankton can still glow even when inside another creature.


The marine phenomenon can be best seen during moonless nights. Scuba divers can wave their arms or run their fingers on the sand while under the sea to cause a reaction on the glowing planktons.
