簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 10; 背的軟條 (總數) : 11 - 12; 臀棘: 3. Distinguished from all congeners, except Micropterus tallapoosae, by the absence of red or orange pigmentation on fin rays (fin rays green or yellow-green); from M. tallapoosae and M. chattahoochae by having 68-72 lateral-line scales (vs. 61-67 ) and 30-32 scales around caudle peduncle ( vs. 26-29); from M. chattahoochae by its narrower head (postfrontal width 11.2% SL vs. 11.8%); and from M. coosae by its head width 11.2% (vs. 11.0%); from M. chattahoochae and M. cf. coosae (Savannah River) by a smaller tongue tooth patch (less than 1.0 mm in 51.7%, absent in 34.5% of specimens vs. in 66.7% or more and absent in 9.0% or less) and from M. warriorensis by more often having a tooth patch (absent in 34.5% vs. 82.9%). It further differs from all species by a unique pigmentation pattern along the midline of the body, having 6-12 blotches with the anterior 6-9 shorter, wider vertical bars followed posteriorly by rounded spots (Ref. 93229).
