Even with proper nutrition and housing, iguanas may develop health problems or become injured. You may think the hatchling is cute, and easily housed in a terrarium. Green iguanas originate from the rain forests of northern Mexico to southeastern Brazil where the temperatures and humidity are high. Iguanas live in the trees and bask in the sun. Their captive environment must duplicate this as much as possible.
Green iguanas are egg layers.
Like many turtles, the eggs are buried in the sand by the mother and once the eggs hatch, the hatchlings are on their own. They can grow up to 6 feet and weigh 18 pounds. With proper care, they may live 15 years or more. Heat Iguanas are cold-blooded and require supplemental heat for proper digestion. If a reptile is cold it cannot properly digest its food and is more likely to become ill.
