The spotted bass (Micropterus punctulatus) is a species of freshwater fish sunfish family (Centrarchidae) of order Perciformes. One of the black basses, it is native to the Mississippi River basin and across the Gulf States, from central Texas through the Florida panhandle. Its native range extends into the western Mid-Atlantic States and it has been introduced into eastern North Carolina and Virginia. It has also been introduced to southern Africa, where it has become established in some isolated waters. It is often mistaken with the similar and more common largemouth bass.
