You are invited on a special "behind the scenes" tour of this extraordinary facility... from the outrageous otters of the River Journey building to the playful penguins of the Ocean Journey building, and everywhere in between. Enter the Tennessee Aquarium, on of the world's largest freshwater aquariums. Millions of people have marvelled at the wondrous creatures, both big and small, that live within its walls. But most visitors only see the animals through a large viewing glass. That's only part of their story. There's an entire world of interesting animal behaviours that remain unseen. To experience this, you have to be adventurous enough to go...beyond the looking glass.
