Color-morphing chameleons

Color-morphing may sound less intimidating than, say, baring teeth or dragging hooves, but male chameleons rely on such psychedelic intimidation to ward off male rivals, according to a new study.

Chameleons are popularly thought to use their color-changing abilities to blend into their environments, but, in recent years, researchers have found this shade-shifting may play a larger role in social interactions than in camouflage. (Live Science)
