River Journey / Discovery Hall
As the water from the Tennessee River meets the Ohio River and empties into the mighty Mississippi, a moist, swampy environment is created.
Guests explore an underwater world where vibrantly colored sunfish float like jewels or peak into the swamp nursery where baby alligators bask. They can also meet an ancient-looking lake sturgeon that is making a comeback in the rivers of Tennessee as part of a long-term restoration effort led by the Tennessee Aquarium Conservation Institute.
Visitors can also see the nation's largest salamander, the hellbender, which breathes through its skin, as a variety of tree frogs chirp and call around them.
