• Jordan Robin, 26, recorded the phenomenon at Plantation Point in Jervis Bay
• This rare event only occurs on the shoreline there once or twice each year 
• It is caused by tiny organisms dubbed 'sea sparkle' that glow when disturbed
• Otherwise the microscopic creatures cause the water to look reddish instead

Mesmerising footage shows the moment bioluminescent algae glow bright blue as a photographer runs his hand through sea water off the coast of Australia.

Jordan Robin, 26, captured the gorgeous natural phenomenon which he found taking place at Plantation Point in Jervis Bay, on Australia's east coast.

The rare event — which only happens there once or twice a year — is caused by a microscopic organisms dubbed 'sea sparkle' that glow when disturbed.

In the video, the award-winning photographer can be seen moving his hand through the water, which triggers the algae to glow with an eerie, bright blue light.

'This rare occurrence only usually happens once or twice a year,' said Mr Robin, who hails from New South Wales, Australia.

'The video was taken on the 14th of January 2020.'

'What can be seen as a red tide during the day, the microalgae Noctiluca scintillans produces a bright blue glow at night, like seen in the video,' Mr Robin added.

Commonly called the 'sea sparkle', 'sea ghost' or 'fire of the sea', Noctiluca scintillans is a microscopic single-celled organism.

Each individual Noctiluca scintillans is around 0.02 inches (0.5 millimetres) in diameter and has a tentacle-like 'flagellum' that helps it eat plankton.

The microscopic creatures bob around in the water column, regulating their buoyancy in order to move up and down.

WHAT DO WE KNOW ABOUT SO-CALLED 'SEA SPARKLE'? 

Commonly called the 'sea sparkle', 'sea ghost' or 'fire of the sea', Noctiluca scintillans is a microscopic single-celled organism.

They can appear as a red tide in the daytime but when disturbed, however, they glow bright blue.

In high enough numbers, this effect can even be detected by satellites orbiting the Earth.

This phenomenon is called the 'milky seas effect', or 'mareel' — as derived from the Old Norse for 'sea fire'.

Each individual Noctiluca scintillans is around 0.02 inches (0.5 millimetres) in diameter and has a tentacle-like 'flagellum' that helps it eat plankton.

The microscopic creatures bob around in the water column, regulating their buoyancy in order to move up and down. 

They are found widely distributed across the world's oceans.
