Lizard Flashes and Dances
During mating season, male veiled chameleons signal their aggressive intentions and fighting prowess by adjusting the brightness of their skin. Individuals with bright stripes are most likely to charge. Once in combat, those whose heads most quickly brighten are likely to win a bout.
Male side-blotched lizards establish territories where they consort with one or more females. When challenged, males perform aerobic displays to each other. The duration of display accurately reflects a male’s physiological state and determines the winner.
