Notice the Anoles big pouch, they do this when their territoty is threatened. Or to attrcact a mate.
I had 6 of these as pets that lived 8 years, double their lifespan. They only ate live crickets. I had a large cage I made for them to get sunlight during the summer months. They had plants to sit on in their large terrarium, and I sprayed misted water on them and the plants at least 3 times a day. They also drank watr from small dish. I also gave them heat lamps, and made sure their tank was never moldy or wet. They can live a long time with care. Also had UV lights on top of their tank, with a wire mesh lid for fresh air.
