Glowing blue beach in China

Xiangbi'ao Beach in Changle City in southeastern China suddenly glowed blue when night fell between July 30 and August 4, according to People's Daily Online.

This special phenomenon is created by a type of seaweed with the scientific name Noctiluca scintillans, also known as "sea ghost" or "sea spark".

Photographers, reporters and tourists flocked to Xiangbi'a Beach to witness the phenomenon. Photos taken at the scene showed a faint fluorescent green streak moving with the waves crashing onto the shore.

According to scientists, Noctiluca scintillans is an algae that is harmful to marine life as well as the fishing industry. This is a single-celled organism that usually eats plankton and is also food for many other organisms. This type of algae grows very quickly when nitrogen and phosphorus released into the sea by humans increase.

Glowing seas are not uncommon in China. The phenomenon has been observed in several cities in the past, including the eastern city of Dalian in April and the southern city of Shenzhen in May.
