Abstract

Unlike other primates, the South American titi monkey,Callicebus moloch, does not exhibit sex-differences in the size or shape of the canine teeth, or in the extent of loss or fracture from excessive use. Males and females have similar canines as well in each of six subspecies ofC. moloch. The lack of dimorphism is related to the low level of aggression in this species.

摘要

与其他灵长类动物不同，南美伶猴（Callicebus moloch）在犬齿的大小或形状上，以及在因过度使用而导致的磨损或断裂程度上，均未表现出性别差异。在伶猴的六个亚种中，雄性和雌性的犬齿也都相似。这种两性异形的缺乏与该物种较低的攻击性水平有关。
