Fig. 3. (A) Relative capacity for fatty acid oxidation, expressed as a ratio of HOAD/CS activity, and (B) relative anaerobic capacity, expressed as a ratio of LDH/CS activity, of pharyngeal jaw muscles of Tramitichromis intermedius (means ± S.E.M). Gray bars represent males, and white bars represent females. Asterisks indicate significant difference in activity for muscles between males and females (P<0.05). Abbreviations: levator externus 2 (LE2), levator externus 3 (LE3), levator externus 4 (LE4), levator posterior (LP), protractor pectoralis (PP), pharyngeohyodius (PH), pharyngeohyodius cleithralis externus (PHCE), pharyngeohyodius cleithralis internus (PHCI), retractor dorsalis (RD), axial muscle (Ax), 3-hydroxyacyl-CoA dehydrogenase (HOAD), citrate synthase (CS), L-lactate dehydrogenase (LDH).
