Beloved Bonobo Max Passes Away at Columbus Zoo

Columbus, Ohio – The Columbus Zoo and Aquarium is mourning the loss of Max, a beloved 9-year-old bonobo, who passed away on June 18 following an unexpected and complex medical condition.

Born on November 8, 2015, Max quickly became a favorite among staff and visitors alike due to his lively personality and deep social connections. He was known for his intelligence, curiosity, and the strong bonds he formed with both his bonobo family and the animal care team.

According to the Columbus Zoo’s official statement shared via Facebook on July 24, Max appeared healthy and active shortly before he was found unresponsive during a routine wellness check. Veterinary professionals acted swiftly, initiating intensive care and bringing in external specialists to provide continuous support over six days. Sadly, despite their efforts, Max did not recover.

A necropsy revealed that Max suffered from gastric ulcers and signs of heat-related illness. While the sequence of events remains unclear, zoo veterinarians believe the ulcers may have led to his rapid health decline. The zoo emphasized that Max had access to proper care, including water and shaded areas, to ensure his comfort.

Max was a vital member of the zoo’s bonobo troop, a group that reflects the zoo’s ongoing commitment to the conservation of endangered great apes. Bonobos, sharing over 98% of their DNA with humans, have been under the zoo’s care since 1990. The average life expectancy of a male bonobo in managed care is approximately 31 years.

Although Max’s life was cut short, his impact on the Columbus Zoo and its visitors remains profound. His legacy lives on through the continued conservation work and the remaining 13 bonobos who call the zoo home.

“Max was deeply loved and will never be forgotten,” the zoo shared. “His spirit brought joy and connection to everyone around him.”
