This article will explore the best locations to observe bioluminescence in Costa Rica and provide practical tips to enhance your experience. Continue reading to discover more about this remarkable spectacle. 

What is Bioluminescence?

Bioluminescence is a natural phenomenon in which living organisms produce and emit light through a chemical reaction involving luciferin and the enzyme luciferase. This process results in a cold blue light, that does not generate heat, distinguishing it from sunlight.

Commonly found in marine environments, bioluminescence is observed in organisms such as plankton, jellyfish, and various fish species. These creatures use light for multiple purposes, including attracting prey, deterring predators, and facilitating communication. The glow of bioluminescent plankton is particularly visible when movements, such as from boats or swimmers, agitate the water.

While often associated with the ocean, bioluminescence can also occur in terrestrial environments, as seen in insects like fireflies and certain species of fungi in decaying wood. For these organisms and other marine life, light serves similar roles, helping attract mates or repel predators, highlighting the fascinating functions of bioluminescence in nature.
