Tony, one of the oldest animals at the Audubon Zoo in New Orleans, died on May 17. Cause of death was not released. He was 44.
Born in a Mississippi zoo, Tony was three years old when he moved to Louisiana. In general, hippos live up to 45 years in the wild and a few years longer in captivity. An African hippo, Tony spent most of his days submerged in water to keep cool and support his large body.
Tony lived with his mate, Rosebud, for 16 years. She died in 1989 at the age of 19 after giving birth to a female hippo named Duffy. The baby died six days later because she refused to eat after her mother died. Zoo officials tried to force feed Duffy under anesthesia, but to no avail.
Tony was the only remaining hippopotamus at the zoo.
