The family Iguanidae includes a diverse group of lizards commonly known as iguanas. They are primarily found in the Americas, particularly in tropical and subtropical regions. Iguanids are characterized by their robust bodies, long tails, and distinctive dewlap, which is a flap of skin under the throat. Many species are herbivorous, feeding on leaves, flowers, and fruits. Iguanidae encompasses several genera, including Iguana, Ctenosaura, and Amblyrhynchus. These lizards are known for their adaptability to various habitats, from rainforests to deserts. Some species, like the Marine Iguana, are unique for their ability to swim and forage in the ocean.
