This is the hilarious moment a girl with buck teeth met her doppelganger - a fish with giant gnashers.

Footage shows student Ruby, 21, kneeling in front of a fish tank while a parrotfish appeared to stare back at her in amazement.

She laughed when her friend pointed out that her large pearly whites were similar to those of the fish.

Self-deprecating Ruby then copied the animal's facial expression, emphasising her protruding upper front teeth while the fish also opened its mouth to compare its own teeth with hers.

Ruby, who wears a brace to correct her overbite, said: 'Thankfully I'm not self-conscious. My teeth are what I was born with. And now we know the fish was, too. He's my little dental soulmate.

'My friend found it funny when we saw the fish. So did other people when they watched the video, so I'm happy that I've made people smile.'

Ruby's friend Sohan Vamora recorded the amusing scene in West Sumatra, Indonesia, on January 28.

He said: 'They were like twins. They look the same. Even their eyes are almost alike. It was so funny.'

Parrotfish have a beak-like structure of fused teeth, giving them a buck-tooth appearance. These fish use their teeth to scrape algae off coral and rocks.
