A, untreated crayfish (control) ; B, both eyestalks removed; C, three pairs of walking legs removed; D, both uropods removed. In the groups where legs or uropods were removed, the regenerated legs or uropods were removed again one day after the third molt. Roman numerals I, II, III, IV and V, show the 1st, 2nd, 3rd, 4th, and 5th molt, respectively. Large variation, however, was observed among the individuals. For example, in the first molt the earliest crayfish molted on the seventh day but the last crayfish molted on the fifty-third day. As clearly shown in Figure 1, this variation became more pronounced in the later molts. Eyestalkless crayfish. Twelve of 23 treated crayfish died between the third and fifth molts. The remaining 11 completed all five consecutive molts within 43 clays. T50 from the first to the fifth molt was 6 ( compared to the value of.
