Fig. 10. Anterior views of the position of the hip (black inverted triangles), knee (red circles), ankle (yellow squares), metatarsal (green triangles), and toe tip (blue diamonds) for a single C. calyptratus moving on a level perch (A) and a level treadmill (B), and a single D. dorsalis moving on a level treadmill (C). Each panel is a composite of four strides, with approximately 25 points per stride. The mean position traveled by the mid-dorsal line was standardized to z=0.
