Fig. 3. Mean horizontal displacement of the limbs of (A) Tupaia glis and (B) Galea musteloides during stance phase. Pivot heights were scaled to the same vertical distance (=100%). Arrows indicate one-pivot-height distance away from the horizontal projection of the pivot's perpendicular. Note the caudal displacement of lift-off position with increasing age and the more consistent touch-down position. Animals are colour coded according to age (see Table 1).
