Fig. 5. Tracings from videotapes showing lateral (left) and dorsal (right) views of different gap-bridging behaviors. (A) Crawling behavior of a snake with SVL=136 cm crossing a 67 cm gap. (B) Lunging and tail wrapping behaviors of a snake with SVL=106 cm crossing a 52 cm gap. The most anterior anchor points in A and B are the fifth right peg and the third left peg from the edge of the initial perch, respectively. The white marks indicate intervals approximately one-eighth SVL along the body of the snake. The times before contacting the destination perch are to the left of each figure. The portion of the snake spanning the gap was nearly straight during crawling, whereas early in the lunge the body had several lateral bends that were later straightened.
