Anoles are abundant in the tropical and sub-tropical western hemisphere. While there are nearly 200 species throughout the hemisphere, only one species is native to North America. Anoles are very capable climbers and are frequently seen on the sides of buildings, on trees and fences. Their color changes in response to light and temperature. They will be green in the cool shade of a plant and brown when out in the heat on a fence. This species of anole can reach 8 inches in length.
