Sea water glitters with neon blue in NE China
A rare scene of sea water turning into neon blue color was caught on the seashore near northeast China’s Dalian City on Saturday night.
This is a natural phenomenon caused by a chemical reaction called bioluminescence.
It is typically seen in calm waters, when billions of micro-organisms emit light when they are disturbed by waves or currents in the wake of ships that stir up oxygen.
Experts say the illuminating mechanism of micro-organisms is activated to scare off predators.
