Captive iguanas often live to be 10-12 years old. There are reports of them having lived past 20 years in captivity. Only about a third of the iguanas sold in pet stores survive to maturity because of importation stress, improper diet, temperature and sunlight. In the wild, the number is even lower because the babies are finger-food for a number of jungle predators.
The lizard with the shortest lifespan is the chameleon, which typically lives just one to three years in captivity. Most lizards live an average of 10 to 20 years. Geckos and iguanas both live into their teens or early 20s. Other lizards, such as the Mexican Beaded Lizard, sometimes live into their 30s.
