Fig. 8. Cellular redox potential in muscle tissue of A. opercularis
individuals throughout the swimming experiment. A0–A4 smaller
individuals [open circles, N=8–17, shell height
50.42±4.185 mm (mean ± s.d.)]; B0–B4: bigger individuals
[filled circles, N=9–18, shell height 69.18±2.747 mm
(mean ± s.d.)]. Groups with the same letter are significantly different
from each other with P<0.05.
