An enormous fish has been discovered after an unsuspecting dog walker stumbled upon the endangered creature.
The fish, reported to be roughly four metres in length, was discovered at Oxwich Bay in Wales on June 10, as reported by WalesOnline.
The dog walker said they noticed a sizeable object in the distance and went over with their pooch, Sasha, to take a closer look. The dog walker quickly realised it was an unusually large sea creature, describing it as "the biggest fish we've ever seen".
The fish has since been identified as an Atlantic bluefin tuna - an endangered species and the largest of its kind, according to the World Wife Fund for Nature (WWF).
Ecologist Thomas Faulkner, who works closely with the Wildlife Trust of South & West Wales, recognised the fish and offered his thoughts on why it might have found itself washed up on Welsh shores.
He said that bluefin tuna were "recolonising south western coastland...after previously going extinct".
Mr Faulkner added that this particular species was "typically rare visitors to the UK and even rarer to Wales".
"They can reach up to four metres long, so you can identify this one just from the sheer size of it," he said, adding: "the south or westerly winds could have washed it up from Cornwall or the Celtic deep."
