Description:
The Pygmy Madtom is a federally endangered species that is known from only a few locations in the Tennessee River Drainage. They live over gravel substrates in swift-moving water of medium rivers. As members of the catfish family, all madtoms have whiskers (barbels) around their mouth with taste buds that aid in finding food. As the common name suggests, Pygmy Madtoms are smaller catfish reaching a maximum size of only 1.5 inches!
