Appendix A<br />

One cycle <strong>of</strong> spectacle blood flow in the resting<br />

coachwhip<br />

This appendix is a video file <strong>of</strong> one cycle <strong>of</strong> blood flow in a coachwhip snake’s spectacle vasculature.<br />

<strong>The</strong> file name <strong>of</strong> this video file is “Appendix_A_-_spectacle_flow_at_rest.mov”. <strong>The</strong> false colour cast<br />

is due to the near-infrared capture. <strong>The</strong> video begins with spectacle vessels constricted and therefore<br />

invisible. <strong>The</strong> dark lines and spots across the image are scratches and abrasions in the spectacle scale.<br />

At 11 seconds into the clip, blood flow begins in a ventral to dorsal direction. It ceases again just<br />

before the end <strong>of</strong> the clip.<br />
