• Movie 1 -

  Movie 1. Chrysopelea paradisi gliding flight sequence 1. In this clip, the snake jumped from the launch branch and landed out of the field of view, making a small turn at the end of the trajectory. The snake (mass 27·g and SVL 63·cm) traveled a horizontal distance of 12.8·m, reaching a maximum speed of 9·m·s^–1 and minimum recorded glide angle of 27°. The view is from an overhead video camera attached to the right side of the tower. The snake launched from a height of 9.62·m. The yellow and black markers on the ground are references used in trajectory reconstruction. Recorded at the Singapore Zoological Gardens in Singapore.

• Movie 2 -

  Movie 2. Chrysopelea paradisi gliding flight sequence 2. The glide trajectory in this sequence is similar to that in Movie 1 but is shown to illustrate the view from the second overhead camera on the left side of the tower. This medium-sized snake (mass 36·g and SVL 69·cm) traveled a horizontal distance of 14.7·m, reaching a maximum speed of 9·m·s^–1 and a minimum recorded glide angle of 27°.

• Movie 3 -

  Movie 3. Chrysopelea ornata aerial locomotion sequence 1. In this clip, the snake jumped from a height of 9.4·m and traveled a horizontal distance of 4.5·m. This was one of the longest trajectories recorded for this species; although of similar size (mass 43·g and SVL 62·cm), there is a large contrast between it and the C. paradisi individuals in Movies 1 and 2. The view is from directly overhead. Recorded at the Prince of Songklha University in Thailand.

• Movie 4 -

  Movie 4. Chrysopelea ornata aerial locomotion sequence 2. This clip further illustrates the dramatic difference in aerial performance between C. ornata and C. paradisi. This relatively large snake (mass 150·g and SVL 89·cm) only traveled a distance of 3.1·m when launched from a height of 7.3·m. C. ornata is more robust than C. paradisi and forms a less flattened shape in cross-section when airborne. Recorded in Lockport, IL, USA.
