The Iguana is a species of lizard inhabiting various tropical regions, including parts of Central America, South America, the Caribbean and Mexico. The common name comes from the Taino word “iwana.” On average, mature adults reach lengths between 5 to 6 feet (1.5 to 1.8 m). Certain species have a unique light-sensing organ that acts as a “third eye.” This parietal eye is photoreceptive and helps the animal regulate hormone production for thermoregulation and control circadian rhythmicity. A keen sense of vision allows iguanas to see and distinguish between different shadows, colors and shapes, and to detect movement at varying distances. High levels of visual acuity enable the iguana to navigate through densely forested habitats efficiently. Visual cues are used to communicate with other individuals. These lizards are strict herbivores, consuming various types of foliage and vegetation. Herbaceous iguanas require a powerful bite force to consume and digest plant material properly.
