Abstract
Like humans, other primates, including spider monkeys (Ateles geoffroyi), show handedness biases. However, evidence is mixed on whether spider monkeys exhibit a species-level bias. Spider monkeys are also unique in that they also have a prehensile tail that functions as a fifth limb with remarkable fine motor control, Figure 1. An open question is whether hand preferences in spider monkeys relate to how they use their tails, which may also show side biases. Such patterns could reflect behavioral lateralization. We explored whether hand and tail side preferences align, suggesting individual- or species-level lateralization.
