HOW LONG DO IGUANAS LIVE?
Because of heavy predation in the wild, iguanas are lucky to live to the ripe old age of 7-9 years. However, in captivity, with the proper husbandry, an iguana can live up to 20 years or more.
Sadly, too many iguanas do not live out their full life expectancy in captivity. This is a direct cause of poor diet, inadequate housing and/or lighting.
If you are thinking of buying or adopting an iguana, be prepared to house a lizard that has a potential life expectancy of a small dog or cat.
