sorry, but just the opposite is true...The spotted bass has a top dorsal fin that is clearly connected while the largemouth bass has a separate or almost separate dorsal fin. Also, the front dorsal fin on a spot has 9 spines, while the largemouth has only 7. Another good indicator (besides the tooth on the tongue of spotted bass) is the lines of black dots along the side belly of the fish (below the lateral line). Largemouth do not have those black dot lines. The fish in the picture is a spotted bass.
