Loxahatchee, Florida (CNN) -- Senior citizens are common in Florida but one 74-year-old is in a class of her own: "Little Mama" is believed to be the oldest chimpanzee in captivity. Born in Africa, she was one of the first residents at Lion Country Safari theme park in Loxahatchee, Florida, about 20 miles west of West Palm Beach. "She came here when the park opened in 1967," said Lion Country Safari Wildlife Director Terry Wolf, who has been with the park just as long. Wolf said the park's owners bought her from a pet dealer. "It was a whole different world then," explained Wolf. "Chimps in pet shops that were babies at that time could go for 10 grand."
