Gorilla break glass at Henry Doorly Zoo and Aquarium in Omaha, Nebraska Caught on Camera!

OMAHA, Neb. (KMTV) – A video of a gorilla at Omaha’s Henry Doorly Zoo and Aquarium has gone viral.

Zoo Curator, Dan Cassidy, says with three gorillas, aged 17 to 22 trying to establish dominance in the same space, they're bound to see testosterone and aggression as these gorillas transition into adulthood.

In the video you can see the reflection of a little girl pounding on her chest as she looks at the male gorillas. One of the gorillas, known as "Kijito", charges to the glass and breaks through the first of three layers of protective glass.

The zoo says this isn't the first time they've seen this before. It's common for the glass to break because of environmental or engineering causes. Gorillas also beat on the glass to makes sounds that scare off their peers.

Curators say while the gorilla did break through a layer of glass, the zoo checks and replaces the glass frequently.

The three gorillas in the exhibit are currently transitioning from blackbacks to silverbacks, as they enter into manhood. ​
