Spotted bassScientific name:
Micropterus punctulatusAlternative common names:
Spotty, spots, Kentucky spotted bass, spotted black bass.
The spotted bass has been introduced to southern Africa where it has become established in some isolated waters. Similar to the largemouth and the smallmouth bass, it is called the 'in-between' species. It is distinguished from the smallmouth bass by the dark, blotchy lateral band from head to tail. It tends to be found in areas with more current than largemouth bass like, and usually inhabits areas that are too warm, turbid and sluggish for smallmouth bass.
