Utah's Hogle Zoo Mourns the Passing of Sea Lion Diego

Utah's Hogle Zoo is mourning the passing of male California sea lion, Diego, who passed away on October 20, 2025.

Diego was diagnosed with degenerative disc disease in 2024, a spinal condition that affected his mobility and caused limited movement in his rear flippers.

Over the past year, Diego's animal care and veterinary teams worked closely to provide ongoing treatments for his degenerative disc disease, including laser therapy, medications, training adjustments, and habitat evaluations to ensure mobility and comfort.

Despite the care and treatment, Diego's condition suddenly worsened, and he showed a significant decrease in appetite and behavior, indicating discomfort, and unfortunately, did not improve.

No statement.
