When it first opened, the Tennessee Aquarium was the largest freshwater aquarium in the world. With the expansion added in 2005, it has so much more.
The Tennessee River Journey
We begin our visit in the River Journey building, which is the original freshwater building. As we go up a two-story escalator (an elevator is available for those who need it), we learn that we will follow the life of a raindrop from the sky to the sea.
You can go to the bayou country in the Delta Swamp section and look at all the alligators, ducks, and freshwater fish of the Mississippi. You can watch American otters playing, and look at some of the largest catfish on display in an aquarium (a blue catfish weighing in at 90 pounds.)
