Russia: The terrifying fish has shocked scientists as it appears to have the teeth of a human.

If you thought a boy with shark teeth was weird, now there's a fish with human teeth!

Russian fisherman Aleks Korobov, 50, has 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 one of the worlds weirdest animals 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 what looked like human teeth.

He said "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.

"Inside were a load of human teeth."

He then rushed to his local pub to show his friends the mysterious catch.

His friend Anton Efimov, 60, said "We know Aleks can tell some tall tales but when he came in and said he had a fish with human teeth we thought he’d certainly been drinking.

"But then he got it out and we were totally shocked.

"None of us had ever seen anything like it in our lives."

Aleks then contacted the Institute of Fisheries and Oceanography for their expert opinion.

Expert Gennady Dvorykankin said: "We had to do an autopsy and carry out a series of examinations to determine the species and an explanation for the teeth.

"We are convinced it is a member of the Piranha family, and that it is a herbivore piranha, not one of the meat eating ones you see in films.

"It is very unlikely that it made its way from its natural tropical waters to our Arctic and then into the river so we can only assume it was dumped by an owner of exotic fish," he added.

Thrilled Aleks said: "I don’t think people will be doubting my fishing stories again after this."
