The Family Iguanidae consists of a diverse group of primarily large, herbivorous or omnivorous lizards, including iguanas, spiny-tailed lizards, and related species. They are found mainly in the Americas and parts of the Caribbean, inhabiting forests, deserts, and coastal areas. Iguanids typically have robust bodies, long tails, strong limbs, and well-developed claws for climbing or digging. Many species display colorful skin and dewlaps used in communication and territorial displays. Ecologically, they play important roles as herbivores, seed dispersers, and prey for larger predators, and several species are popular in the pet trade due to their distinctive appearance and behavior.
