指猴拥有高度适应的手，它们使用专门的第三指通过敲击来调查潜在的食物来源，并使用第三或第四指将食物转移到嘴里。在呈现食物或新奇物体后，对 11 只圈养指猴（10 只野生捕获；1 只圈养繁殖）进行了观察，并对握持、敲击和手指喂食的手部使用情况进行了评分。尽管没有一致的模式，但其中 8 个人对 3 种措施中的一项或多项表现出显着的手部偏好。这些初步结果与其他狐猴物种的结果进行了比较。
Aye-ayes possess highly adapted hands, using their specialized third digits to investigate potential food sources by tapping and the third or fourth digits to transfer food to the mouth. Observations were conducted on 11 captive aye-ayes (10 wild-caught; 1 captive-bred) following presentation of food or novel objects, and hand use for holding, tapping and digit-feeding was scored. Eight of the individuals showed significant hand preferences for one or more of the 3 measures, although there was no consistent pattern. These preliminary results are compared to those from other lemur species.
