TOO MUCH MONKEY BUSINESS: Chilling Footage Shows Gorilla Charging, Slamming Glass Enclosure in San Diego Zoo, Cracking It (VIDEO)

Denny the gorilla and the smashed glass.

Denny’s flexing left zoo visitors terrified.

A scary event took place at a California zoo, where an enormous gorilla can be seen charging and slamming at the glass wall of its enclosure.

The scary display smashed a layer of the thick glass panel.

The New York Post reported:

“Denny, a 10-year-old western lowland gorilla, shattered one layer of a three-layered tempered glass panel at the San Diego Zoo’s gorilla forest habitat on Saturday, zoo officials confirmed in a statement to The Post.

Footage obtained by CBS8 captured him catapulting toward the glass wall, causing several onlookers to gasp and scream as they walked away from the habitat.”

The ape was not injured in the incident.

Denny and the other gorilla will be cared for while the panel is replaced.

Denny lost a brother, Maka, who died from a cardiac event in August.

“Dr. Erin Riley, an anthropology professor at San Diego State University, said several factors could have provoked the behavior, including Denny’s grief for his late brother, CBS8 reported.

’Gorillas, particularly males, will often do what we call ’charging displays’, as a kind of an act of like showing off’, Riley told the outlet. ‘What I don’t know, of course, since I wasn’t there, is whether or not there was something that kind of provoked that display behavior’.”

In front of people at the San Diego Zoo, a gorilla broke through one of three layers of glass that separates them from visitors. The zoo said the gorilla habitat will remain closed for now until the glass can be replaced.
