Fig. 3. The concentration of myoglobin in the swimming muscles of different age
classes of Weddell seals. The concentration of myoglobin was significantly
higher in the swimming muscles of juveniles compared with either pups or
adults. In addition, myoglobin concentration was also significantly higher in
adults compared with pups. Values are means ± s.e.m. (N=6).
* denotes significantly greater than pups;
denotes significantly greater than adults (P<0.05, ANOVA).
