The iguana is a family of lizards native to tropical areas of Central and South America and the Caribbean. The green iguana, which is a popular pet, lives in tropical rainforest areas near water, such as rivers or streams. Other iguanas live in the dry, hot desert. Like other reptiles, the iguana is cold blooded meaning they do not produce their own body heat. If an iguana is cold, it will lie on warm rocks to soak up the sun's heat. Green iguanas are omnivorous meaning they eat both plants and meat, but they mostly eat plants. Play the following videos to learn more about the iguana.
