Fireflies adorning a tree as they flicker like Christmas lights – this is a beautiful sight. But swimming through clear water as you watch glowing plankton surrounding your limbs is an experience. In the darkness of night you feel like you’ve waded into a mythical sky, the stars at your fingertips.
Glowing plankton – or bioluminescent plankton – differs all around the globe. It can glow in different colors and intensities. The most typical color is blue, while red, orange, and green are less common. When the water is disturbed, for instance with a swift motion of a hand, the glowing dots multiply.
Here at Coconut Beach, our plankton glows blue and is plentiful. Because our beach is secluded, we do not have much artificial light disturbing the darkness after the sun sets. So when the moon is far from full and the waves are not too rough, we are more than happy to turn off the lights from our restaurant to ensure that our guests see the plankton as clearly as possible. We also provide snorkeling gear for those who want to see the sparkling critters vividly and below the water’s surface.
The little guys cannot be seen without a microscope. They are, of course, harmless. Yet they are kind enough to put on this unique light show for us every night, and we invite you to come enjoy it with us.
