The Mooneye is found from Gulf Coast drainages, including the Mobile Basin, the Mississippi River Drainage, including the Tennessee and Cumberland river drainages, extending north to Hudson Bay drainages in Canada. Construction of dams has greatly reduced the range of this migratory species. They are found in open waters of medium to large rivers and tolerate turbidity. Mooneyes have a deep silvery body with a fleshy keel along their belly. As the common name suggests, Mooneyes have large silvery eyes that resembles the moon.
