The variability in number of oocytes or diverticulae in the ovariuterus of scorpions, increases during development. It is low in the small, rudimentary oocytes or diverticulae, increasing in the embryonic ones, and is considerably higher in the post-partum diverticulae. Possibly, because there are generally more than one generation of the latter that can be traced in the ovariuterus. Variability in embryo and juvenile numbers as well as the latter’s mass vary within and among species as well as between different families. The lowest variability in number of embryos was 30 %, and in litter size about 20 %. The lowest variability in juvenile mass was 1.8 % and the highest 12.1 %. The significance of these findings for the reproductive ecology and survival of scorpions is discussed.
