Bioluminescent Bay

Vieques Island, Puerto Rico - April 2007

Mosquito Bay on Vieques Island is home to the most bioluminescent water in the world. The microscopic dinoflagellates that live in the water glow whenever they are disturbed which means that every splash creates a wondrous glowing aura around whatever is moving in the water. It is believed that the light is the plankton's defense mechanism.

Anything that touches the water will glow, this includes boats, fish, stingrays and people.

The wake stirred up by the boat's outboard motor giving off an eerie glow.

The water is not only safe to swim in but it is a fantastic experience. If you remain perfectly still, the glowing stops but as soon as you move, you become surrounded with greenish light.
