Fig. 6. Comparison of the relationship between the scaling with body mass of whole-animal metabolic rate (_O2), muscle aerobic capacity (CS activity) and a muscle metabolic process (AP resynthesis) following tail-flipping responses in three species of crustaceans. Data are reported as means ± s.e.m. All regression slopes were significantly different from zero except for CS activity (_O2=32.0M^–0.21, r²=0.95, P<0.05; AP resynthesis rate=1.22M^–012, r²=0.77, P<0.05; CS activity=6.18M^0.09, r²=0.68).
