Why bioluminescence is a must do whilst in the Cayman Islands!

The Wonder of Bioluminescent Bay

One of the most remarkable and exciting experiences awaits you along the coast of Grand Cayman. At night, you will experience a beautiful blue-green light in the water as millions of tiny organisms glow in the dark.

It is a magical experience for any who are present as the sun falls beyond the horizon, and you see the waters begin to glow.

The fascinating light is caused by tiny half plant and half animal creatures give off a bluish and greenish light when they are agitated. They must be agitated a lot judging from the constant and eerie light that comes from the water for miles around. The light is bright enough to enable you to read a book from it.

Each gallon of seawater contains roughly 720,000 single-celled creatures per gallon that are called bioluminescent dinoflagellates. This display of creature created light is best experienced during the phase of a new moon. The Guinness Book of World Records has declared the bioluminescence the brights example of this type of creature induced light in the world.

The light occurs when these small creatures come into contact with each other or are shaken or disturbed in any manner. Since they are in the ocean, there is a great propensity for both of these events to occur.

Currently, these creatures are in danger of being exterminated due to the rapid development of the area. There is no swimming allowed in the area, and any chemicals or lotions, such as sunscreen, bug repellent, and such items will adversely affect the ecosystem of the bay. There are also penalties for throwing trash objects of any kind into the bay.

The smallest foreign object, a piece of trash, or contamination can kill thousands of the creatures immediately. The threat of pollution that would result from further development is also a major concern.
