Mary Beth McDonald, left, reacts with her daughter, Catie, 8, after petting an American alligator held by house zoologist Todd Quinn during a live reptile show held at the Imaginarium in Fort Myers on Thursday. The McDonalds are in town from Green Bay, Wis., visiting Mary Beth’s father, and she said that her children “wanted to come back” to the museum during their visit. “They will touch anything,” she said. The exhibit is part of the “Reptiles, Real and Robotic” special exhibition at the museum through May 14. It features live reptiles and their mechanical counterparts.
