The oxygen consumption of some profundal and other muddwelling animals was studied in relation to varying periods of starvation, varying temperatures and varying oxygen content of the water to find that this oxygen uptake corresponds to moderately active, not to a basal, metabolism. It is shown that for a number of activities in which the effects of respiration may safely be assumed, the values of the critical increments are consistent with those determined for processes of resppiration. Examples of these adaptations include blindness to semi-blindness caused by a lack of light, bioluminescence, and a sluggish metabolic rate, among other things.
