MARINELAND, Fla., Feb. 28 (UPI) -- A Florida theme park said its Atlantic bottlenose dolphin, Nellie, believed to be the oldest in human care, marked her 58th birthday with a fish and ice cake.
Nellie's birthday celebration was Sunday at Marineland park.
The dolphin was born at Marineland Feb. 27, 1953, and continues to perform in feeding and petting shows at the facility's Dolphin Conservation Center, The St. Augustine (Fla.) Record reported Monday.
Officials said Nellie is more than twice the average age of a female Atlantic bottlenose dolphin in the wild and 13 years older than Pebbles, the park's next-oldest dolphin.
The Sarasota Dolphin Research Program said it knows of one female dolphin believed to be older, a member of a free-range community of dolphins in Sarasota Bay. She was estimated to be about 60 years old in 2010.
