An iguana is a type of reptile belonging to the family Iguanidae. They are predominantly found in Central and South America, as well as the Caribbean. Iguanas are known for their distinctive features, including a long tail, robust body, and a characteristic dewlap—an extension of skin beneath their chin. These reptiles are primarily herbivorous, feeding on a diet of leaves, flowers, and fruits. Iguanas are also popular pets due to their unique appearances and relatively calm nature when properly cared for. However, they require specific environmental conditions to thrive in captivity.
