S1 Data -

Contains data used for Fig 2 (sheet 1: critical swimming speed in BL s−1; sheet 2: SMR and MMR; sheet 3: hypoxia tolerance) and Fig 3 (sheet 4: gene expression of Hb, Mb, Cytgb, and Ngb), as well as S1 Fig (sheet 2: age versus mass), S2 Fig (sheet 1: critical swimming speed, cm s−1), S3 Fig (sheet 2: SMR versus mass), S4 Fig (sheet 2: MMR versus mass), and S5 Fig (sheet 2: AAS and FAS). AAS, absolute aerobic scope; BL, body length; Cytgb, cytoglobin; FAS, factorial aerobic scope; Hb, haemoglobin; Mb, myoglobin; MMR, maximum metabolic rate; Ngb, neuroglobin; SMR, standard metabolic rate.
