Some people took the trouble to come to the California coast at night to see the unusual blue glow of the water.
A series of photos and videos posted by locals on the “Instagram” website show the unusual flash of blue water.
In one of the videos, a man threw his hands into the water, leaving traces of glowing, and in another, someone shot bright waves.
Bioluminescent plankton – the single-celled and two-celled algae known as nightlight or sea candle were reported to be behind the water’s glow.
