1 mmHg=approx. 0.01316 kPa.
PwO2crit, critical hypoxic water O2 partial pressure required for maintenance of standard metabolic rate; IMR, immobile metabolic rate; AMR, active metabolic rate; Ucrit, maximum sustainable aerobic swimming speed (please see text for details); BL, body length.
Values are means ±1 S.E.M., N=8 in all cases.
