Iguanas are large lizards that belong to the family Iguanidae. They are primarily found in tropical areas of Central and South America, as well as the Caribbean. Iguanas are known for their distinctive long tails, spiky crests along their backs, and vibrant green color, although some species can be different shades. They are herbivores, mainly eating leaves, flowers, and fruits. These reptiles are excellent climbers and often reside in trees. Iguanas have a unique ability to regulate their body temperature by basking in the sun or seeking shade. They can also drop their tails as a defense mechanism to escape predators, allowing them to survive in the wild.
