1. The rate of oxygen consumption of the antarctic amphipod Orchomonella chilensis (Heller) was determined over a graded temperature series from -1.8° to 12°C.
2. The regression coefficients of double-log plots of rate:weight and weight-specific rate:weight were temperature-dependent. The correlation coefficients between size and rates of consumption were highly significant and varied significantly with temperature. Q10 varied with size.
3. The acutely determined R-T curve shows some regulation between -1.8° and 6° C. Metabolic compensation was evident.
