Southern sea otters (Enhydra lutris nereis) offer a unique opportunity for testing this approach because (1) they consume a wide variety of prey that span multiple trophic levels, habitats, and ecologically defined functional groups; and (2) individual diet specialization can be validated with ...
通过检查196只带有无线电标记的南方海獭(Enhydra lutris nereis)的纵向数据,我们发现使用工具的个体,特别是雌性,可以接触到更大和/或外壳更硬的猎物。这些机械优势转化为在食品加工过程中减少牙齿损伤。我们还发现,工具的使用减少了获取不同猎物、牙齿状况和能量摄入之间的权衡,所有这些都取决于环境中相对猎物的可用性...

Weaning represents a major ontogenetic dietary shift in southern sea otters (Enhydra lutris nereis), as juveniles must transition from depending on mother's milk to independently processing hard-shelled invertebrates. When the skulls of juveniles have reached sufficient maturity to transition to a duro...
