Great numbers of hyænas are produced in Africa, which also gives birth to multitudes of wild asses. In this species each male rules over a herd of females. Fearing rivals in their lust, they carefully watch the pregnant females, and castrate the young males with their teeth, as soon as they are born.[1] The pregnant females, on the other hand, seek concealment, and endeavour to bring forth in secret, being desirous to increase their opportunities of sexual indulgence.
