A stunning clip shows dolphins glowing as they glide through bioluminescent waves off the Californian coast.

The remarkable footage, which was filmed at Newport Beach on Wedensday (April 22nd), shows the marine mammals swirl through the Pacific waters while giving off an otherworldly hue of electric-blue light.

"We were out for a few hours and on our final stretch back we finally had two dolphins pop up to start the incredible glowing show," filmer Patrick Coyne told local media.

The effect is caused by bioluminescent algae which has been blooming in recent weeks off the Californian coast.
