Footage posted by a photographer through his account on the social networking site "Instagram", showed a swarm of dolphins swimming through vital algae off the coast of California.
Photographer Patrick Quinn, who took the video off the coast of Southern California, commented that the scene was one of the most charming nights of his life.
The display was caused by dolphins disturbing microorganisms, which glow with some form of response to fear.
"We were outside for a few hours, and in the end, Delphine appeared to start an incredible glowing show," Cowen wrote on Instagram.
It is noteworthy that the glow that appears during swimming dolphins, which is known as "sea fire", is produced by mono-cellular microorganisms known as "dinoflagellates".
Microorganisms produce two chemicals - luciferin, luciferase, and an enzyme. When combined, the enzyme stimulates a reaction to luciferin - leading to a distinctive blue flash that lasts up to about 100 milliseconds, according to the British newspaper "Daily Mail".
