Similarly, the zoeae at 25° C. have completed the third molt before those at 20° C. have begun. At molt IV (Fig. 4) there is an even greater difference in zoeae reared at different temperatures and at 20° C. the spread of time for the molt is considerable. This difference is carried over into the molt to the first crab (Fig. 5). As shown in Figure 6, the duration of.
