The intermembral index compares the length of the hindlimbs to the length of the forelimbs and is used to determine whether an animal is adapted for quadrupedal or bipedal locomotion. A high intermembral index indicates that the hindlimbs are longer than the forelimbs, which is characteristic of bipedal animals such as humans. A low intermembral index indicates that the hindlimbs are shorter than the forelimbs, which is characteristic of quadrupedal animals such as dogs. It is not a measure of overall size or relative strength, and it does not take into account the length of fingers and toes.
