Often seen in parks and residential areas on walls, fences, trees, and low bushes, green anoles reach a maximum length of six to eight inches. Their bodies are slender, with a long, thin tail. Like true chameleons, green anoles have the ability to change color; this ability is limited in anoles, however--coloration is usually green, yellow, brown, gray, or a mixture. Most healthy, non-threatened anoles are bright green in appearance. The male anole has a large pink fan of skin on its neck, called a dewlap, which can be extended for courtship or territorial display.
Active and agile creatures, anoles have specially adapted pads on their feet which permit them to climb, cling, and run on virtually any surface. Another adaptation of the anole is its extremely fragile tail which drops off its body when grabbed, allowing the anole to escape from predators; in time, the anole will regrow a new (although generally shorter) tail. Anoles feed on small insects such as crickets, cockroaches, spiders, moths, and grubs.
I spotted this green anole at the Sabal Palm Sanctuary near Brownsville, Texas.
