POWELL, Ohio -- A 28-year-old black rhinoceros named Kulinda has died at the Columbus Zoo and Aquarium.
Kulinda was humanely euthanized Friday because of her declining physical condition and poor prognosis, zoo officials said.
She had been diagnosed with iron overload syndrome, which results in progressive liver failure.
Kulinda may be remembered by some fans as the rhino they fed apple slices to during keeper talks, zoo officials said. She also used her upper lip to create paintings.
Kulinda was born at the Cincinnati Zoo and Botanical Garden on Oct. 19, 1988, and came to the Columbus Zoo the next year.
The zoo said the median life expectancy for black rhinos in North American zoos is 18.3 years.
