This video from the USA says about itself:
The largest Green Anole ever!
The Carolina anole (Anolis carolinensis) is an arboreal lizard found primarily in the southeastern United States and some Caribbean islands. Other common names include the green anole, American anole and red-throated anole. It is also sometimes referred to as the American chameleon due to its ability to change color from several brown hues to bright green. While many kinds of lizards are capable of changing color, anoles are closely related to iguanas and are not true chameleons. The Carolina is a small lizard; male adults are usually 15 cm (5.9 in) long in adulthood, about half of which is its tail, and it can weigh from 3–7 g (0.11–0.25 oz). Exceptionally, these anoles will grow up to 20 cm (7.9 in) in length.
From Breaking News:
A lizard species in Florida has evolved very quickly to deal with invaders

In as little as 15 years, lizards native to Florida – known as Carolina anoles or green anoles – have adapted to deal with the threat of an invading species of lizard, Cuban or brown anoles.
This video is called Egg-laying brown anole (Anolis sagrei), Aruba. This female brown anole was filmed during digging a hole in the sand in which she layed an egg.
After having contact with the invasive species, said to have first gone to America from Cuba in the 1950s, the native lizards starting perching higher up in trees. Over the course of 15 years and 20 generations, their feet evolved to become better at gripping the thinner, smoother branches found higher up.
The change was rapid. After a few months the native lizards started moving higher up the branches and over 15 years, their toe pads had become larger with stickier scales on their feet.
“We did predict that we’d see a change, but the degree and quickness with which they evolved was surprising,” said Yoel Stuart, a post-doctoral researcher in the College of Natural Sciences at The University of Texas at Austin and lead author of the study.
“To put this shift in perspective, if human height were evolving as fast as these lizards’ toes, the height of an average American man would increase from about 5 foot 9 inches today to about 6 foot 4 inches within 20 generations — an increase that would make the average U.S. male the height of an NBA shooting guard,” said Stuart. “Although humans live longer than lizards, this rate of change would still be rapid in evolutionary terms.”
This latest study is one of only a few well-documented examples of what evolutionary biologists call “character displacement,” where similar species competing with each other evolve differences to take advantage of different ecological niches.
The researchers speculate that the competition between brown and green anoles for the same food and space may be driving the adaptations of the green anoles. Stuart also noted that the adults of both species are known to eat the hatchlings of the other species.
“So it may be that if you’re a hatchling, you need to move up into the trees quickly or you’ll get eaten,” said Stuart. “Maybe if you have bigger toe pads, you’ll do that better than if you don’t.”
The research was published in the journal Science.
