The Denver Zoo euthanized Rudy, a 32-year-old black rhinoceros, on Tuesday. 

He had spent the month in end-of-life care, suffering from age-related mobility challenges and chronic health conditions, including iron overload disorder, the zoo posted online. 

Rudy will be remembered for inspiring staffers in their conservation quests, as a “once-in-a-lifetime animal” with a “tender spirit.”

His oversized presence will be missed by staff and zoo visitors alike. 

“That 3,000-pound hunk o’ love made everyone feel special and consistently had a gentle, healing energy radiating out of his pores,” wrote animal care specialist Gracie, in a statement. “He was a beam of golden light, a carrot connoisseur, a world-champion duration farter, and a friend to everyone with a hand that was willing to rub him behind the ears.”

So, what happens next to Rudy’s body? 

Just after Rudy died, the Denver Zoo Conservation Alliance’s vet team examined his body to better understand his decline. 

The vets hope the research contributes to the larger body of knowledge about black rhino care and conservation, zoo spokesperson Jake Kubie explained in an email. 

“After that, we are shipping tissues out to other facilities and organizations for further research, and the rest of his remains will go to Denver Museum of Nature and Science,” he wrote. 

Zoo staffers are heartbroken. 

“Rudy is the air that I breathe and the heart in my chest,” wrote Catherine, an animal care specialist, in a statement. “I live to watch him lumber his way over to me every morning, not even looking for a snack, but my attention. Feeling his warm breath huff out of his nostrils on my face as he greets me with a sniff.” 

“He was more than a rhino in my care but my friend, confidante, my reason for coming in every single day and giving my best because he deserved nothing less,” Suzanne, another animal care specialist, wrote. 

“Though my life has been thoroughly rocked by his absence, I will always be thankful for those quiet moments together, and will always take a second to come back into my body on the craziest of days because of the lessons he has taught me,” Gracie wrote. “I thank you and love you forever, Rudy the Reasonable.”
