"Perched over the river that runs through downtown Chattanooga, the Tennessee Aquarium offers a novel way to discover the magic of sea life. Exhibits here trace the path from mountain streams to the sea, showcasing aquatic animals in representations of their natural habitats. In the ocean display, visitors can see exotic fish gliding over multicolored coral reef formations, but the most popular attractions are the river otters cavorting in cascading waterfalls, and the penguins diving in and out of their cold-water habitat. The aquarium also features thousands of insects that flutter from flower to flower in the butterfly garden, as well as a gigantic IMAX 3-D theater that screens fascinating movies about nature and science."
