Arboreal and semiterrestrial guenons show similar osteological features of the limbs across a wide range of species, environments, and geography, while the more terrestrially committed guenons exhibit greater morphological divergence. An ecomorphological comparison of two sympatric guenons living in Kibale Forest, Uganda, reveals an array of anatomical adaptations for terrestriality in the limbs of Cercopithecus lhoesti similar to those found in Erythrocebus patas. In contrast, Cercopithecus aethiops, although also frequent users of the terrestrial environment, generally exhibit fewer morphological adaptations characteristic of a terrestrial lifestyle. It appears that significant morphological modification for terrestriality has occurred twice within the diverse radiation of living guenons with C. aethiops perhaps representing a third group in the making.
树栖和半陆生的长尾猴在广泛的物种、环境和地理范围内表现出相似的四肢骨骼特征，而更倾向于陆地生活的长尾猴则表现出更大的形态差异。对生活在乌干达基巴莱森林的两种同域长尾猴进行生态形态学比较发现，洛氏长尾猴四肢具有一系列适应陆地生活的解剖学特征，类似于赤猴。相比之下，黑长尾猴虽然也是陆地环境的频繁使用者，但通常表现出较少的陆地生活方式特有的形态适应特征。在现存长尾猴的多样化演化过程中，对陆地生活的显著形态改变似乎发生了两次，黑长尾猴可能代表正在形成的第三类。
