Magical scenes caused by glowing plankton have been spotted on the Welsh coast.
The impressive phenomenon was captured over the weekend illuminating the shoreline with a bright blue glow.
Last week the bioluminescent sight, caused by 'sea sparkle' or Noctiluca scintillans, was seen lighting up the night sky for the first time this year in Anglesey .
But keen photographers have also tracked it down as far south as Southerndown beach in Bridgend and Pobbles Beach in the Gower.
Part-time photographer Lee McGrath said he had been out taking pictures of the Milky Way when he first spotted the glow on Thursday night.
The 44-year-old said: "I could see it out of the corner of my eye. I returned on Friday at 1am with some friends to photograph it properly."
Lee, from Bridgend, urged those visiting the area to be wary of the tides while visiting at night.
He said: "It's a waiting game. Spend time in the dark to let your eyes adjust to the darkness, keep all torches off and a keen eye in between the rocks.
"If if is there it will show itself eventually. It will be obvious if is is particularly strong, but not guaranteed as on Saturday evening there was hardly anything.
"Just be patient and [with] a bit of luck and you will see it."
The awe-inspiring sight is caused by bioluminescent plankton which produces a blue light when disturbed.
The tiny organisms produce light using a chemical called luciferin as a defence mechanism to draw predators towards the creature trying to eat the plankton.
While it is usually spotted in warm coastal waters, like those in the Maldives and Tasmania, they are also known to appear in parts of Wales during the summer months.
Programmer Tim Bow also captured the scene over the weekend on the Bridgend beach.
The Swansea photographer said: "It's unpredictable, as you can imagine.
"We saw it in Aberavon and Caswell last year but it's quite faint.
"It's an ethereal colour, it's not something you expect to see and the fact there was only three other people there was pretty nice.
"It's even better in real life than it is on photos."
As well as Southerndown beach, the sight has also been reported at Pobbles Bay in the Gower.
Tim added: "People have spotted it down on Pobbles Beach. People were swimming in the water which a lot of people want to discourage and it's quite dangerous at night."
