The common name for an iguana is simply "iguana." Iguanas are a group of lizards that belong to the family Iguanidae, primarily found in Central and South America, as well as the Caribbean. The most well-known species is the green iguana, which is popular as a pet due to its distinctive appearance and relatively docile nature. Iguanas are primarily herbivorous, feeding on leaves, flowers, and fruit, and they are known for their impressive climbing abilities. In their natural habitat, they play an essential role in the ecosystem as both herbivores and prey for larger predators.
