Fig. 3. Semi-logarithmic plots comparing the complete (open triangles, solid line) and corrected (filled triangles, broken line) bonito swimming speed–_O2 data sets. [Note: the corrected data set was obtained by the selective removal of 10 elevated-_O2, slow-speed data points (see text).] The two data sets are described by the best-fit equations: y=107e^0.015x, r=0.74, for the complete data set; y=70e^0.020x, r=0.84, for the corrected data set. Extrapolation of these equations to zero speed estimates bonito SMR as 107±22 mg O₂ kg^-1 h^-1 for the complete data set; 70±10 mg O₂ kg^-1 h^-1 for the corrected data set.
