Fig. 9. The kinematics and the path traveled by a snake using the lunging behavior to cross a gap. (A) Forward and (B) lateral displacement versus time, and (C) a lateral view of the path traveled by the snout of the snake (SVL=106 cm) while crossing a 52 cm gap. The times between the last thirteen successive points are 33 ms; all other time intervals between successive points are 200 ms. The snake touched the perch on the far side of the gap at 0 s. Different colored symbols indicate four attempts to bridge the gap, for which only the last was successful. The rapid forward and vertical velocities (slope) within the last 0.5 s indicate when the snake lunged. The end and top center of the initial perch are at the origin of the x, y and z axes.
