Among those fortunate enough to capture the spectacle was photographer and wildlife enthusiast Duane Evans, from Gorseinon, who has spent years searching for the elusive display.
"I have been hunting bioluminescent plankton for about five years," he said.
Describing his latest experience Duane said: "I was amazed. I was lucky enough to catch it in the early hours of Wednesday morning between 2am and 3am."
Bioluminescence is light emitted by living organisms as the result of chemical reactions within their bodies.
Certain species of plankton produce their own light when disturbed by breaking waves, swimming fish, or predators.
The same natural ability is also found in some species of squid, jellyfish, fireflies, and glow-worms. Although individual plankton are microscopic when vast numbers gather together and are disturbed at the same time they create a spectacular blue glow that can illuminate the waves.
The magical displays often attract photographers and nature lovers with images and videos frequently going viral on social media.
Those hoping to catch a glimpse of the phenomenon are advised that sightings depend on the right environmental conditions and can never be guaranteed, making each appearance a special event for those lucky enough to witness it.
