Brachiation was the main form of locomotion and took place along branches and boughs in the upper canopy. The posture during feeding depended on the substrate, with the gibbons sitting on branches but hanging in twigs. During foraging the gibbons hung more, even on branches, but as only short stops were made this is probably to increase mobility. Feeding on fruit took place mainly in the middle canopy on small trees; feeding on leaves and foraging occurred evenly throughout the middle and upper canopies. Gibbons are light mobile animals with a rapid and direct form of locomotion that enables them to exploit dispersed food sources and to defend a large territory.
臂行是主要的移动方式，沿着上层树冠中的树枝和大树枝进行。进食时的姿势取决于支撑物，长臂猿坐在树枝上，但在细枝上则是悬挂着。觅食时，长臂猿更多地悬挂着，即使在树枝上也是如此，但由于只是短暂停留，这可能是为了增加移动性。以水果为食主要发生在中层树冠的小树上；以树叶为食和觅食在中层和上层树冠中均匀分布。长臂猿是体型轻盈、行动灵活的动物，具有快速直接的移动方式，这使它们能够利用分散的食物来源并保卫大片领地。
