Quizplus · Accepted Answer

The intermembral index is the ratio between the length of the arms and the length of the legs. A value higher than 100 indicates that the arms are longer than the legs, while a value lower than 100 indicates that the legs are longer than the arms. Since the gibbon has an index of 129, its arms are significantly longer than its legs.
