Andatu - the famous sumatran rhino calf - wrote this on his Facebook page earlier today:

“On Monday, my grandfather, Ipuh, died. He lived at the Cincinnati Zoo in the United States, which is also where my dad was born. I never met Grandpa Ipuh, but they say he was about 33 years old – the oldest Sumatran rhino in any zoo. He also fathered three calves – my dad Andalas, my Aunt Suci and my Uncle Harapan – making him the most prolific male of our species in captivity. This makes me very proud.”
