Peyote, (from the Nahuatl word peyotl), is a small, spineless cactus. It is native to southwestern Texas and through central Mexico. It is found primarily in the Chihuahuan desert and in the states of Tamaulipas and San Luis Potosi among scrub, especially where there is limestone.
It is well known for its psychoactive alkaloids, particularly mescaline. It is used world wide as an entheogen, and supplement to various transcendence practices, including meditation, psychonautics, and psychedelic psychotherapy. Peyote has a long history of ritual religious and medicinal use by indigenous Americans.
Chameleons are a distinctive and highly specialized clade of lizards. They are distinguished by their parrot-like zygodactylous feet, their separately mobile and stereoscopic eyes, their very long, highly modified, and rapidly extrudable tongues, their swaying gait, and the possession by many of a prehensile tail, crests or horns on their distinctively shaped heads, and the ability of some to change color. Uniquely adapted for climbing and visual hunting, the approximately 160 species of chameleon range from Africa, Madagascar, Spain and Portugal, across south Asia, to Sri Lanka, have been introduced to Hawaii, California and Florida, and are found in warm habitats that vary from rain forest to desert conditions.
The most well-known creature that changes color, the chameleon, usually does not do so for camouflage purposes, but instead to express its mood.
