Anolis is a genus of lizards commonly known as anoles, found primarily in the Americas. They are known for their ability to change color and their distinctive throat flaps, called dewlaps, which are used in communication and mating displays. Anoles are typically small, with many species adapting to various habitats, including forests, grasslands, and urban areas. These lizards are insectivorous, feeding on a diet of insects and other small invertebrates. Anolis species are often studied in ecology and evolutionary biology due to their diverse adaptations and behaviors. They play a significant role in their ecosystems as both predators and prey, contributing to the balance of their environments.
