Chameleon \Cha*me"le*on\ (k[.a]*m[=e]"l[-e]*[u^]n), n. [L. Chamaeleon, Gr. chamaile`wn, lit., ``ground lion;'' chamai` on the ground + le`wn lion. See Humble, and Lion.]

(Zo["o]l.) A lizardlike reptile of the genus Cham[ae]leo, of several species, found in Africa, Asia, and Europe. The skin is covered with fine granulations; the tail is prehensile, and the body is much compressed laterally, giving it a high back.

Note: Its color changes more or less with the color of the objects about it, or with its temper when disturbed. In a cool, dark place it is nearly white, or grayish; on admitting the light, it changes to brown, bottle-green, or blood red, of various shades, and more or less mottled in arrangment. The American chameleons belong to Anolis and allied genera of the family Iguanid[ae]. They are more slender in form than the true chameleons, but have the same power of changing their colors.

Chameleon mineral (Chem.), the compound called potassium permanganate, a dark violet, crystalline substance, KMnO4, which in formation passes through a peculiar succession of color from green to blue, purple, red, etc. See Potassium permanganate, under Potassium.
