How old can a lizard become?

The lifespan of a lizard varies significantly depending on the species. Some small lizards may live only a few years, while larger species, such as iguanas and some monitor lizards, can live 15 to 20 years or more in captivity. In the wild, factors like predation and environmental conditions can affect their lifespan. Overall, with proper care, many pet lizards can live long and healthy lives.
