Nerves or hormones (adrenaline secreted by the adrenal gland and hormones of the hypophysis) Actually, the chameleon is constantly changing its color. Chameleons possess in chromatophores (cells that give skin's color) two types of pigments: one black (melanin) and another one, of various colors. Chromatophores retire or display their ramifications, changing this way their color. Their movements are under the control of nerves or hormones (adrenaline secreted by the adrenal gland and hormones of the hypophysis). These colors respond perfectly to the needs of their arboreal life: 130 species of chameleons out of 156 live in trees. Colors displayed by the chameleons vary from gray to whitish, black, vivid green, green-yellow, olive or blue. http://news.softpedia.com/news/Why-Do-Chameleons-Change-Color-47360.shtml Jun 02 09, 11:34 PM
