"It is a very sad day for Shedd Aquarium – we've lost a family member," said Tim Binder, vice president of collection planning at Shedd Aquarium. "As one of the oldest of her species living in a U.S. aquarium, and one of the first dolphins here at Shedd, we've had the tremendous privilege to care for, and learn from, Tique for more than two decades. The relationships and bonds our dedicated staff built with her during that time make this loss a difficult one."
