Study shows male chameleons fighting prowess tied to color changing abilities

(Phys.org) —Two researchers from Arizona State University have found that male chameleons use their color changing abilities for far more than hiding from predators. In their paper published in the journal Royal Society Biology Letters, Russell Ligon and Kevin McGraw describe a study they conducted with captive chameleons that showed that male veiled chameleons use their colors to intimidate other males and that head coloring can predict who might win in a scuffle.
