Giant jellyfish with '40ft tentacles' captured on camera
Iestyn Morgan said he wants to raise awareness about the 'threats our seas are facing'
A free diver has said he "couldn't believe his luck" after spotting a giant jellyfish off the Welsh coastline.
Iestyn Morgan, from Pembrokeshire, said the lion's mane was the "length of a bus" with a size of about 10 to 15 metres (32ft 8in to 49ft 2in).
The 21-year-old conservationist, who records footage for social media to raise awareness about the "threats our seas are facing", said it was the first lion's mane he had seen in Wales.
More commonly found in the colder waters off Scotland, a marine biologist said although the lion's mane sting was "nasty", it was not dangerous.
The lion's mane jellyfish was spotted near the Pembrokeshire coast
Morgan said he was swimming near Trefin Beach in Pembrokeshire when he spotted the tentacles in the water.
"Three turned to 10, and then to 20. They just kept on coming," he added.
The jellyfish was so big the tentacles went "beyond the range of visibility".
He initially thought it was a compass jellyfish, which are native to UK waters, before realising it was too big.
