World's oldest hippo dies at 62 from arthritis
CHICAGO (AFP) - Donna, believed to be the world's oldest hippo, has died at the age of 62 after living more than two decades beyond the massive mammal's usual life expectancy, zoo officials said.
Donna had lived most of her life in the small town of Evansville, Indiana at the Mesker Park Zoo & Botanic Garden.
"It is with great sadness for us to announce that Donna, the world's oldest living Nile hippopotamus in captivity, was humanly euthanised this morning due to her declining quality of life caused by her debilitating severe arthritis," zoo director Amos Morris said in a statement on Wednesday.
Donna was born at what is now the Memphis Zoo in 1951 and arrived at Mesker Park on Aug 7, 1956.
