Fig. 2. Right lateral and dorsal views of A. sagrei (snout–vent length 5.5 cm, mass 5.0 g) moving on level 1 cm (A–D) and 10 cm (E–H) diameter perches at footfall (A,E), midstance (B,F), endstance (C,G) and midswing (D,H). The elapsed times after footfall of successive images for the 1 cm and 10 cm are 32, 60 and 88 ms and 36, 72 and 108 ms, respectively. The vertical lines on the perches are 5 cm apart. The forward speeds of the strides on the 1 cm and 10 cm perches were 52 and 55 cm s^–1, respectively. See http://www.biology.uc.edu/faculty/jayne/videos.htm for digital videos of Anolis locomotion.
