Abbreviations: AFF, Australian fur seal female; AFM, Australian fur seal male; ASF, Australian sea lion female; ASM, Australian sea lion male; BMR, basal metabolic rate; NFM, New Zealand fur seal male; SMR, standard metabolic rate; sSMR, mass-specific standard metabolic rate. The number following the species and sex identity is an individual identifier. Bold values indicate months when the seal was moulting. NA indicates a month when that individual was not measured.
