Residents and visitors at Aberavon Beach in Port Talbot have been left amazed after witnessing the sea glow in brilliant shades of blue, caused by a rare display of bioluminescent plankton. The phenomenon has been observed over several nights, with the waves lighting up as they roll onto the shoreline.
Photographer Captures Elusive Display
Duane Evans, a wildlife photographer from Gorseinon, captured the spectacle after years of searching. He said: "I have been hunting bioluminescent plankton for about five years. Some nights there's no luck but I have been lucky the last few times." Evans described the experience as "amazing," adding that it is "right on our doorstep." He compared the sight to the Northern Lights, saying: "I don't know what's better – the Northern Lights or the plankton."
How Bioluminescence Works
Bioluminescence is light emitted by living organisms through chemical reactions within their bodies. Certain plankton species produce light when disturbed by breaking waves, swimming fish, or predators. Although individual plankton are microscopic, vast numbers gathering together can create a spectacular blue glow that illuminates the waves. The same ability is also found in squid, jellyfish, fireflies, and glow-worms.
Conditions and Popularity
The rare phenomenon depends on environmental conditions and cannot be guaranteed, making each appearance special. Evans noted his latest sighting occurred between 2am and 3am on Wednesday. The displays often attract photographers and nature lovers, with images and videos frequently going viral on social media.
