Anolis

Green Anole
The green anole is generally about five to eight inches (13 to 20 cm) long. Females are usually smaller and can be under five inches (13 cm) long. Green anoles have adhesive lamellae on their foot-pads for crawling along walls, much like geckos. Able to change color, the green anole can be anywhere from bright green to browns and grays. One thought is that the green coloration is related to dominance.

Their color varies depending on their mood, temperature, humidity and health. They are often referred to as the American chameleon, although they are unrelated to chameleons. Their tails and bodies are long and slender and their heads have pointed snouts. Males are distinguishable from females because males have a pink dewlap, a flap of skin that hangs in an arc below their neck. This dewlap is used for attracting females and in territorial disputes.
