Incredibly frightening footage has gone viral of a large silverback gorilla trying to attack a zoo visitor through a glass enclosure.
The gorilla, known as Kijito the silverback, lives at the Henry Doorly Zoo in Omaha, Nebraska.
Kijito is seen charging and jumping into the glass when the selfie-taking visitor, managing to remain incredibly calm, who had his back turned to the enclosure.
According to the man with the camera, the same gorilla broke a window last year.
He wrote online that ‘he is quite the character and plays with us whenever we go to the zoo’.
The poor gorilla seems stunned when he slams into the glass, instead of the red target that he was pursuing.
