Overview

• Denny, a 10-year-old western lowland gorilla, struck a tempered viewing panel on Saturday, cracking one of its three protective layers, according to the zoo.
• Officials confirmed no people or animals were injured and said the gorillas are being cared for behind the scenes while the damaged panel is replaced.
• A social-media video posted by local outlets shows the charge into the glass as visitors react, and an eyewitness described a large crack directly in front of her.
• The zoo has not provided a repair timeline or said whether the replacement will use a different glass product, the San Diego Union-Tribune reported.
• Experts cited typical male gorilla display behavior as a likely explanation and noted other possible factors, including crowd interactions or social stress after a recent group loss.
