Fig. 2. Schematic figures of the right hindlimb for a single complete stride for C. calyptratus (A) and D. dorsalis (B) moving on a level treadmill. The five figures for each animal indicate (from left to right) footfall, midstance, endstance, midswing and the subsequent footfall. The red, blue, yellow and green portions are the femur, tibia, metatarsal and toe, respectively. Both of the strides are to the same scale.
