Fig. 2

Mean mass-specific metabolic rate (μL O₂ min⁻¹ g^−0.67) of swimming sea turtle hatchlings during the frenzy and post-frenzy. Error bars represent 95% confidence intervals. We present measurements made during routine swimming (circles with solid error bars) and maximal swimming (triangles with dashed error bars). Statistical differences between frenzy and post-frenzy metabolic rates within species are signified with the symbols * and ^. Numbers represent statistical similarities among species’ routine swimming metabolic rates within each behavioural stage, respectively. Letters represent statistical similarities among species’ maximal metabolic rates during the frenzy and post-frenzy, respectively. Statistical differences were determined using mixed-effects models and Tukey’s pairwise comparisons. Two outliers (Green frenzy: 126.97 μL O₂ min⁻¹ g^−0.67, Green 3wk post-frenzy: 159.87 μL O₂ min⁻¹ g^−0.67) were omitted from the figure to facilitate easier comparisons among behavioural stages and species. Both outliers were included in the analysis
