Now those are some cool pictures. To confuse the matter even more these 2 spp, Ozark Bass (Ambloplites constellatus) and the Rock Bass (Ambloplites rupestris) have another similar species called the Shadow Bass (Ambloplities ariommus). They are all in the Centrarchidae Sunfishes family. The Rock bass actually was found in the Neosho river drainage of Southwestern Missouri and is found mostly in the northwest corner of Arkansas. The Shadow and Ozark are more numerous with the Shadow Bass having a almost statewide distribution. The Ozark Bass belonging mostly in the White River Drainage. Technically there are many differences but Google and the Internet should help with most of it. I have caught all 3 species in north Arkansas and they all are very fun when wading the cool streams (lakes) of Arkansas. When you get into Scale Rows, Anal fins, Ratios of Body Depth to Standard Length and it can get way out there and boring. The most eye catching is the Color Blotching Pattern of the (Shadow) vs the Irregular Spotting (Ozark).
