Bioluminescent plankton
Bioluminescent plankton are tiny marine organisms that emit light when disturbed, creating a magical glow in the water. In Colombia, this natural phenomenon can be observed in several coastal locations, particularly along the Caribbean coast. This glowing effect, often referred to as the “sea of stars,” provides a mesmerizing experience, you can see the water light up as you swim, kayak or simply walk along the shore. The phenomenon is best observed on dark, moonless nights when the glow is most visible.
Fun Facts:
- Bioluminescence in plankton is typically caused by a chemical reaction that occurs when these microorganisms are agitated, such as by waves, boat wakes, or even swimming. The light produced is often blue or green and creates a glowing effect in the water.
- Viewing bioluminescent plankton has become a popular ecotourism activity in Colombia. Guided night tours often include kayaking or boat trips to areas where the phenomenon is most visible, offering a unique experience for nature lovers.
