Jamaican Gray Lizard (<em>Anolis lineatopus</em>) (IMAGE) University of Missouri-Columbia Caption The throat fan of the Jamaican Gray Lizard (Anolis lineatopus) appears to glow when light passes through it from the back. The new study shows that this glowing effect increases the efficacy of the lizard's visual signal by making the colors of the throat fan stand out against the background.
