Tadpole Madtom
Noturus gyrinus
About This Fish

The Tadpole Madtom is widespread throughout lowland central and eastern North America from Texas to Saskatchewan and east to Massachusetts, including the Mobile Basin and the lower Tennessee and Cumberland river drainages. They live over soft substrate in slow water of creeks to large rivers. As members of the catfish family, all madtoms have whiskers (barbels) around their mouth with taste buds that aid in finding food. Like all members of the genus Noturus, Tadpole Madtoms are smaller catfish reaching a maximum size of five inches.
