Beachgoers amazed as glowing algae puts on stunning bright blue underwater light display

[China] Footage has emerged of glowing blue algae putting on a stunning underwater light show, leaving beachgoers amazed.

The video , shot earlier this month in the port town of Qinhuangdao in north-eastern China, shows the living creatures giving off an ethereal blue glow .

The effect is caused by bioluminescence – the production and emission of light by living organisms.

The phenomenon is found widely in marine animals, especially in the open sea, with about three-quarters of all deep-sea animals producing some form of light.

But it is much less common to find light-emitting creatures so close to the shore.

Even some land-dwelling creatures, such as fireflies, are bioluminescent.

Animals can use this effect to attract prey or a mate, but in algae it is used to startle predators.

It is triggered when the water is disturbed, so it is usually seen in choppy waters.

While such a scene is unlikely to be seen in British waters , bioluminescent animals can be found on almost every continent on Earth .
