    • n chameleon A lizard-like reptile of the family Chamæleontidæ, having a naked body, a prehensile tail, feet suited for grasping branches, and the eye covered by a single circular eyelid with an aperture in the center. There are about 59 species, of which the bestknown is Chamæleon vulgaris, a native of Africa, extending into Asia and the south of Europe. Its body is 6 or 7 inches long, and the tail 5 inches. The skin is cold to the touch, and contains small grains or eminences which are of a bluish-gray color in the shade, but in the light of the sun all parts of the body become of a grayish-brown or tawny color. The extraordinary faculty which the chameleon possesses of changing its color, in accordance with that of the objects by which it is surrounded or with its temper when disturbed, is due to the presence of clear or pigment-bearing contractile cells placed at various depths in the skin, their contractions and dilatations being under the control of the nervous system. Its power of fasting and habit of inflating itself gave rise to the fable that it lives on air. It is in reality insectivorous, its tongue, which is long and covered with a viscid saliva, being darted at its prey and securing it when touched.
