Known as a ratfish, this 300 million-year-old species lives in very deep water where its abnormally large eyes help it to see in the dark.

This particular specimen was reeled up by 19-year-old angler Oscar Lundahl.

“We were looking for blue halibut which is a rare species about five miles (8km) off shore,” he said. “I had four hooks on one line and felt something quite big on the end of it.”

“It took me about 30 minutes to reel it in because it was 800 meters deep.”

“It was pretty amazing. I have never seen anything like it before. It just looked weird, a bit dinosaur-like. I didn’t know what it was but my colleague did.”
