Original title: 57 years old! The world's oldest rhinoceros died on the same day a baby rhinoceros was born
The world's oldest rhinoceros has died in Tanzania at the age of 57.
Fusta, an Eastern black rhinoceros, was first discovered in the Ngorongoro Crater in 1965, when she was only three years old.
She spent 54 years at liberty in the crater, but later in her life, health problems forced her to receive specialist treatment in a shelter.
One of the reasons ngorono has never had a baby rhino is that she has never been a conservationist.
By 2016, Foster's vision was deteriorating, sustained by hyenas.
Dr Freddie & middot; manongi, of the Ngorongoro conservation agency, told the BBC: 'fierce animals, especially hyenas, began to attack her and she developed a very severe ulcer. "By 2016, we have to get her out of the wilderness and take special care of her. '
Symbolically, on the day forsta died, another rhino was born.
"Records show that forsta is the longest surviving rhino in the world, and she died naturally on the night of December 27. '
In the wild, rhinos usually live to the age of 37 to 43, or 50 years in captivity.
The eastern black rhinoceros is listed as an extremely endangered species. Its numbers are dangerously low because they are often poached for their horns, but they are increasing as conservation efforts are added.
