The total number of young crabs lacking their right cheliped was 318, while 293 had lost their left cheliped. The total number of the young crabs with two large chelipeds was 300.

The large chelipeds of young males differ in size relative to the carapace width of the giant cheliped from adult males, the small chelipeds of those young males that still have them, and those of adult females. In short, the large chelipeds of the young crabs are intermediate between the small and giant ones. The numbers of the two sexes were nearly equal after differentiation of the chelipeds had occurred. The sex was determined by examining the abdominal 20 - 1O - O 20 - 10 - April D_ 20 - 10 - O. CARAPACE WIDTH (mm) WITH ONLY ONE CHELIPED D WITH TWO LARGE CHELIPEDS FIGURE 2.
