The Manila Zoo is mourning the loss its longest-living resident, Bertha the hippo.
Bertha, who lived at the zoo since it opened in 1959 was found dead in her enclosure last week, and is believed to have been 65-years-old – the oldest living hippo in captivity, according to Letaba Herald.
Bertha first came to the zoo when she was just 7-years-old.
An autopsy indicated she died due to multiple organ failure, and complications of old age.
Zoo officials say Bertha lived far beyond expectations for her species. Hippos typically live between 4-50 year, both in the wild and captivity.
