الأشواك الظهرية (المجموع) : 10; الأشعة الظهرية الناعمة (المجموع) : 12 - 14; شوكة شرجية: 3; أشعه شرجية لينه: 10 - 11. A member of Micropterus coosae species group but differs from all other members of the group by having red on the distal one-half of second-dorsal, caudal, and anal fins, and entire length of pectoral-fin rays (vs. green, yellow-green, or orange on smaller portions of fins in other species) and midline row of blotches partial to lacking, typically with 6 or fewer anterior vertical blotches with the remainder too diffuse to recognize as blotches or spots (in 76% of individuals; remaining 24% with midline row of blotches extending total body length, having 10-13 blotches). It further differs from M. tallapoosae and M. chattahoochae by a combination of the following characters: smaller scales (2.6 vs. 2.9% SL); higher scale counts, including lateral-line scales (mode 70 vs. 65 or 66; range 68-73 in 83.8% vs. 61-67 in 77.2%), and scale rows around caudal peduncle (mode = 30 vs. 29; range 30-32 in 80.0% vs. 26-29 in 94.1%). It can be further separated from M. warriorensis by the presence of a tooth patch (vs. absent; from M. tallapoosae, M. warriorensis, M. cahabae, M. chattahoochae, and M. cf. coosae (Savannah River) by a narrower postfrontal width 11.0% SL (vs. 11.2% SL or more); and from M. cahabae by the presence of more pronounced white tips on the caudal fin (Ref. 93229).
Inhabits rocky runs and pools of creeks and small to medium rivers (Ref. 205); also found in upland streams (Ref. 10294). Oviparous (Ref. 205).
