A seven-year-old Bertha arrived at the zoo in the Philippines' capital the year it opened in 1959. Zoo officials believed Bertha was the oldest living hippo in captivity at the time of her death. Donna, who died in 2012 at the age of 62 at the US Mesker Park Zoo and Botanic Garden in Evansville, Indiana, was previously said to be the world's oldest hippo, according to media reports at the time. Two years ago, an adult male hippo named Bertie was euthanized at the Denver Zoo in Colorado at the age of 58, the reports said. Bertha's death leaves Mali, a 43-year-old Asian elephant, as the oldest remaining animal among the some 500 residents at the Manila Zoo, Dichaves said.
