Most years in south Wales, the waters along the Heritage Coast and beyond show off the natural phenomenon of bioluminescence.
It’s the “production and emission of light by a living organism” – in this case plankton.
So far this year, there have been a number of sightings, and over the weekend, Porthcawl photographer Mark J Davies took these pictures just down the coast at Aberavon.
Many thanks to Mark for letting the Glamorgan Star use these photographs.
