The zoo's oldest animal is a marabou which lived there even before it was a zoo. I saw it when I went there on July 2022.
Is the Nile Hippopotamus cow known as "Rosa" still alive? She would by now be fifty-five years old, and arrived from Leipzig in 2002.
No, she is not. She was already gone on my first visit, back in early 2014. Gordo, Gurba and Blue (their calf) are the only hippopotamuses in Itatiba.
