TN Aquarium Debuts New Mussels Exhibit
CHATTANOOGA, Tenn. (WDEF) – The Tennessee Aquarium is flexing its mussels with a brand-new exhibit that shines a spotlight on some of the river’s most overlooked but important residents—freshwater mussels.
Housed in the Ridges to Rivers gallery, this exhibit introduces visitors to species like the Purple Wartyback, Threehorn Wartyback, and Painted Creekshell—native to the Duck River, one of the most biodiverse waterways in North America.
Though they may look like simple rocks nestled in the riverbed, freshwater mussels play a crucial role in aquatic ecosystems.
They act as natural filters—pulling in water, removing pollutants, and releasing it cleaner than before. Multiply that by tens of thousands, and these mollusks become a living filtration system for our rivers.
Tennessee is home to more than 70 mussel species, making it one of the most biodiverse regions in the world for freshwater mussels—especially in the Tennessee River Valley.
Unfortunately, mussels are among the most endangered animals in the country.
Pollution, sedimentation, and habitat loss continue to threaten their survival. That’s why education and conservation efforts like this exhibit are so important.
The exhibit is supported by the Tennessee Department of Environment and Conservation, as part of a broader effort to protect water quality and preserve mussel habitats.
In 2024, Governor Bill Lee signed an executive order focused on protecting the Duck River watershed—an essential step toward ensuring clean drinking water for over 250,000 Tennesseans and a healthier future for freshwater species.
With engaging visuals and a powerful message, the Aquarium hopes guests leave with a deeper appreciation for these small but mighty river dwellers—and an understanding of how we all play a part in keeping our waterways clean.
