虽然休息是前肠发酵灵长类动物的主要行为之一（即，colobines），它们的休息姿势很少受到关注。我们假设，colobines更受限制，在其休息的位置比后肠发酵灵长类动物，colobines假设一个坐着休息的位置，为特定的原因。为了验证这一假设，我们采用了两种方法。首先，我们观察了8个物种中的两个圈养个体的休息姿势，并测试了colobines是否比其他灵长类动物更多地以坐姿休息。其次，我们收集了31个物种的自由放养标本的文献数据，并再次测试colobines是否比其他灵长类动物更多地以坐姿休息。这两种方法都表明，colobines花更多的时间在坐姿比其他灵长类动物（73.0%对23.2%在圈养和83.0%对60.9%在野生环境中，分别）。我们推测，消化室的位置和必须经常打嗝消化气体的必要性，迫使colobines采取坐姿，以避免对胸部和呼吸器官的压力。
Although resting is one of the dominant behaviors of foregut-fermenting primates (i.e., colobines), their resting posture has rarely received attention. We hypothesize that colobines are more constrained in their resting position than hindgut-fermenting primates and that colobines assume a sitting resting position for specific reasons. To test this hypothesis, we followed two approaches. First, we observed resting positions in two captive individuals each of eight species and tested whether colobines rested in a sitting position more than other primates. Second, we collected literature data on free-ranging specimens of 31 species and again tested whether colobines rested in a sitting position more than other primates. Both approaches indicated that colobines spent more time in a sitting posture than other primates (73.0% vs. 23.2% in captivity and 83.0% vs. 60.9% in the wild, respectively). We hypothesize that the position of the digestive chamber and the necessity of frequently having to eructate digestion gases force colobines to take a sitting posture to avoid pressure on the thorax and respiratory organs.
