English: Comparison of typical turning behaviour of the tree frog (R. pardalis) (upper video and animated graph) and the torrent frog (S. guttatus) (lower video and animated graph) on the LED-illuminated platform. Such turning takes place during rotation whenever the frogs find themselves facing downhill. Typically, body turning in the tree frog results in loss of body contact, so that the frog is subsequently attaching by its toe pads alone. However, torrent frogs usually turn without permanently losing body contact. Indeed, body contact area increases with the angle of tilt. The graphs show total contact area against platform rotation angle (a measure of time), the moving vertical line indicating the position in the video.
