Studies on the oxygen consumption in tropical poikilotherms

In non-gravid femaleParatelphusa sp. total metabolism decreases with progressive starvation. On the first and on the fourteenth day of the experiment theb values are 0·7449 and 0·7104 respectively. When the starvation is continued to the twenty-first-day, oxygen uptake decreases further in smaller crabs but in the larger crabs the oxygen consumption increases reaching a steadier level when compared to the values of the fourteenth day.
The decrease in weight is progressive but negligible. Hence decrease in oxygen consumption is due to the effect of starvation.
