Summary

Description
English: Use of the LED-illuminated platform enabled the visualisation and measurement of contact area during adhesion to a rotating glass platform. Here, at near 180 degrees (fully upside-down position), the tree frog (R. pardalis) shows dynamic stability, using its toe pads alone. Under the influence of gravity, the limbs slide towards the body and are re-extended at intervals, while the fingers of the fore-limbs slide centripetally towards the hand, again being replaced in an extended position at intervals. Such ‘dancing’ behaviour allows the frog to avoid falling for it keeps the angle between pad and surface as small as possible, avoiding detachment by peeling (see [17] for a full explanation).
