A Florida aquarium will temporarily close to treat its resident prosthetic-tailed dolphin that starred in the “Dolphin Tale” movies. The famous marine mammal is now in critical condition from a suspected infection. The Clearwater Marine Aquarium said in a statement it will shut its doors Friday “to create the best possible environment” for medical staff to treat Winter, a 16-year-old female bottlenose dolphin suffering from a gastrointenstinal infection.
