The iguana is a large lizard native to tropical areas of Central and South America, as well as the Caribbean. They are known for their distinctive long tails, spiky crests along their backs, and vibrant green color, although some species can be gray or brown. Iguanas are primarily herbivorous, feeding on leaves, flowers, and fruits. Iguanas are excellent climbers and often reside in trees, where they can bask in the sun and escape predators. They are cold-blooded reptiles, meaning they rely on external heat sources to regulate their body temperature. Iguanas can live for over 20 years in captivity with proper care.
