A rare fish with human-like teeth has been caught in the United States, leaving baffled beachgoers terrified.

The creature was caught by an angler off Jennette's Pier, a popular fishing destination in Nag's Head, North Carolina.

It was later identified as a sheepshead fish, which has uncanny gnashers - and has now gone viral online.

The fish was reeled in by Nathan Martin, and the photo was shared on Facebook.

The snap shows the nine-pound animal showing off a toothy grin.

The fisherman said he had been hoping to catch a sheepshead fish but was shocked after coming face-to-face with a "mouth full of teeth".

"It's a very good fight when you're fighting on the line, it's a really good catch, and it tastes very good," he told McClatchy News.

The so-called "demon fish" have a mouthful of molars, and two incisors.

The photo was captioned with the hashtag #bigteethbigtimes and it caused a stir on social media.

"Is this where dentures come from?" wrote one user.

The Department of Environmental Quality says the fish are generally found year-round in North Carolina’s coastal waters "ranging from inshore brackish waters to offshore rocky bottom".

It's not the only time a fish has been caught with what appears to be human teeth.

Back in 2014 Russian fisherman Aleks Korobov, 50, confused fish experts after he caught a terrifying looking fish with teeth like a human.

Aleks, from the city of Arkhangelsk in north-western Russia's Arkhangelsk Oblast district, caught it on a fishing trip on the Northern Dvina River.

He thought it was a common bream, but when he went to unhook it he saw it had a mouth full of teeth.

He said six years ago: "It was already dead but when I picked it up and smelt it, I could tell it was fresh.

"I then opened its gills which were nice and red but I noticed the mouth wasn’t right for a bream and when I opened it I nearly dropped the thing in surprise.
