Clearwater, Florida — A prosthetic-tailed dolphin named Winter that starred in the "Dolphin Tale" movies died Thursday evening at a Florida aquarium despite life-saving efforts to treat a gastrointestinal abnormality, aquarium officials said.

The 16-year-old female bottlenose dolphin died while being held by animal care experts who were preparing Winter for a procedure at the Clearwater Marine Aquarium where the famous marine mammal has long resided.

"The CMA family is devastated," the aquarium wrote in a statement, according to CBS Tampa affiliate WTSP-TV.
