CLEARWATER, Fla.—The prosthetic-tailed dolphin that starred in the “Dolphin Tale” movies may be fighting a gastrointestinal infection, officials said.

The Clearwater Marine Aquarium said in a news release on Sunday that staff members noticed on Nov. 1 that Winter was not eating and was acting abnormally. Initial bloodwork showed the possible infection.
