How long do iganas live?

Iguanas can live for up to 20 years in captivity, although their lifespan in the wild is typically shorter. The common green iguana (Iguana iguana) has an average lifespan of 15-20 years, while some species of rock iguanas (Cyclura spp.) can live for up to 30 years. The maximum recorded lifespan of an iguana is 35 years, which was achieved by a captive Galapagos marine iguana (Amblyrhynchus cristatus).
