Female in the Mirror
Females change color to communicate their sexual status to males, Hughes says. Female Mediterranean chameleons, for example, display yellow spots to signal sexual receptivity, according to a 1998 study.
Female social signals may be fewer “because they choose and males are competing to be chosen.”
And if she sees herself in a mirror? It would likely be more subtle than the male reaction, Hughes says—although there isn’t enough knowledge of female chameleons to know for sure.
“Female-female communication in chameleons is generally not well understood,” he says, and may be less obvious than interactions between males.
Color us humans envious of an animal who looks in a mirror and sees little that needs changing.
Male in the Mirror
Chameleon colors aren’t just camouflage, says Eli Greenbaum, an evolutionary geneticist at the University of Texas at El Paso—they also change due to temperature shifts or emotions.
And males get emotional when they see other males that could be rivals for females or habitat.
“Male chameleons will, in most cases, immediately change colors in response to seeing another male, and in this instance, to itself in a mirror,” says Daniel F. Hughes, a doctoral candidate in Greenbaum’s lab. (Related: “What Do Animals See in the Mirror?“).
To illustrate his point, he referred us to a YouTube video of a male panther chameleon, a species native to Madagascar, doing that very thing.
A male chameleon that sees a “rival” would get excited and change from its camo green to noticeable hues of yellow, orange, or even red, says Michel C. Milinkovitch, a biophysicist at the University of Geneva … read more –> http://news.nationalgeographic.com/2016/06/…
