The Georgia Aquarium, Atlanta, USA

The aquatic animals are displayed in five different galleries: Georgia Explorer, Tropical Diver, Ocean Voyager, Cold Water Quest, and River Scout. Each corresponds to a specific environment. At the left as one enters the aquarium is the Georgia Explorer exhibit, geared especially towards children. It features a number of touch tanks with rays and sharks as well as exhibits featuring sea turtles and the wildlife of Gray's Reef – a National Marine Sanctuary off the Georgia Coast. 

The second exhibit, River Scout, also reflects regional environments. It features an overhead river where visitors can see North American fish from the bottom up. In addition to local specimens, this exhibit displays piranha, electric fish, and other unusual freshwater life. 

The third section of the aquarium, Cold Water Quest, features animals from the polar regions of the world and contains most of the mammals in the aquarium's collection. This exhibit includes beluga whales in the aquarium's second largest habitat, Japanese spider crabs, and African black-footed penguins. 

The fourth exhibit, entitled Ocean Voyager, includes the vast majority of the aquarium's water and almost 100,000 fish. This exhibit is designed to feature the life of the Mesoamerican Barrier Reef System, and showcases the aquarium's whale sharks, as well as a 100 foot (30 m) underwater tunnel and the world's second largest viewing window. 

The final exhibit takes an artistic turn, as the Tropical Diver exhibit features many curious and haunting forms of aquatic life, including a living reef with live coral. The aquarium also features a "4D" movie "Deepo's Undersea 3D Wondershow", and other attractions, including the Ocean Voyager – Journey With Giants exhibit hall where the Chedd-Angier-Lewis production company, with Electrosonic Inc., has produced the Open Ocean Touchwall, a dynamic, interactive projection for species identification. 

This is a virtual aquarium where larger than life, fully articulated 3-D renderings of Open Ocean fish swim across six panels assembled to simulate a tank. Guests are invited to reach out and place hands or fingers on the fish. As they do so, fun and informative content bubbles appear to educate the guest about the particular species they have chosen.
