The Aquarium takes viewers behind the scenes at the largest aquarium in the Western Hemisphere - Atlanta's Georgia Aquarium. The Aquarium focuses on the care given to the thousands of individual animals that call the 10 million gallons of water at the aquarium home, and the bonds the staff form with them. The series follows the day-to-day activities of the aquarium's biologists, researchers and trainers as they interact with rescued Southern sea otters and sea lions, endangered African penguins, massive whale sharks and more.
