Fig. 5. Diving metabolic rates (DMR) in relation to mass. Each point is the mean
DMR of an individual seal (N=8 seals). The solid line is the line
fitted by least-squares regression, weighted by the number of dives from each
individual. The equation for this line is: log DMR = log mass (0.76-1.79)
(r2=0.92, P<0.0001). The broken line
represents Kleiber's prediction of BMR in terrestrial mammals.
