This amazing footage was taken at a zoo in Nebraska.
Visitors to Omaha's Henry Doorly Zoo & Aquarium in Nebraska, United States were shocked to witness this fight between two gorillas.
It seems to have been caused when one of the gorillas crossed in front of the other one, causing him to charge and collide into him. After a brief scuffle, the gorillas back off from each other.
Whilst the fight is quite scary to see and the guests were clearly very concerned - with one shouting 'Where are the zookeepers!?' - experts say this is actually a fairly minor scuffle.
Dan Houser, who works at the zoo in question, said: 'It looks like a big battle but on the gorilla scale, it’s no more than one kid pushing another kid.'
Well, if that's the case, we dread to think what a serious fight would look like...
