Bahía Fosforescente de Lajas
Phosphorescent Bay of Lajas (La Parguera)
is a common phenomenon in the open sea, but rarely occurs in coastal bays. In the region of La Parguera are two sheltered bays that exhibit this phenomenon.
At night, the waters of the Phosphorescent Bay and Monsio Jose Bay glow when turned over by the waves, by a passing school of fish or by the simply stiring movement of a
The bioluminescence of the Phosphorescent Bay water is generated by millions of its resident micro-organisms known as dinoflagellates; among which the most aboundant is the Pyrodinium (pyro-dinium-fire). Occasionally, other organisms greater in size may contribute to the emission of the light noticed in the Bay.
The light or "glow" in the water resulting from a chemical reaction between substances in them which when combined, flash. This flashing will occur when the water is stirred to the passage of a boat, water padeling oars, or even by the effect of rainfall.
These organisms are aboundantly found in the Phosphorescent Bay due to the narrow entrance of the bay, and the low tidal fluctuation. The bay is like a trap in which they are concentrated.
