Comments: Right lateral view of lizard running quadrupedally uphill on a treadmill inclined 30 degrees.
Distance between vertical lines in the background grid is 10 cm.
The tread surface is moving opposite to the direction of running. Consequently, movement of the lizard relative to the background is slower than relative to the tread surface.
