Males are territorial and will aggressively defend specific areas that typically include more than one female. Following the mating period, female iguanas find suitable nesting sites, dig their nesting burrow, and lay between 2 and 20 eggs. The female defends the burrow for a short time, to prevent other females from nesting in the same place.
The young iguanas hatch months later, and take about a week to dig their way out of the nest. If they survive the first difficult years of life, when food is often scarce and predators are a danger, land iguanas can live for more than 50 years.
In , the status of the extant populations of land iguanas was considered good. Then in , two populations on different islands Cerro Cartago on Isabela and Conway Bay on Santa Cruz were decimated in less than six months by feral dog packs. Unlike tortoises, adult iguanas are not predator-proof. Saving them meant removing them from their natural habitat until dogs were eliminated. A breeding and rearing center was quickly established, but it was not large enough for all of the adults.
A management technique used only once before in Galapagos, in the s, was implemented. Thirty-eight Santa Cruz iguanas, about half of the original group brought to the center, were released on the small islets of Venecia off the northwest coast of Santa Cruz.
This semi-captive population lived under natural conditions, but the islets had no large areas suitable for nesting. Approximately m 3 of soil was moved to Venecia from Santa Cruz and an artificial nesting area was built. The population thrived. The iguanas on Venecia continue to breed today and many of the resulting juveniles are repatriated to Santa Cruz, approximately every three years.
Unlike tortoises, the young land iguanas could not be repatriated to their original habitat unless the introduced predator problem was solved. Dogs eat adults as well as young iguanas, while cats eat only young animals.
Once feral dogs had been eliminated on both southern Isabela and northwestern Santa Cruz, iguana repatriations were generally successful. The land iguanas of Baltra have a very different history.

The longest of the iguanas is the green iguana. It grows to between 5 and 7 feet 1. The smallest of the group is the spiny-tailed iguana, which grows to 4. The heaviest iguana is the blue iguana. It can weigh up to 30 lbs. Iguanas like warm temperatures because they are cold blooded. This means that the outside temperature is what keeps them warm since they have no way to regulate internal heat with their own bodies.
They typically live in tropical and subtropical forests, deserts and coastlines, according to the San Diego Zoo. The University of Florida also reports that there are iguanas running free in south Florida due to people setting their pets loose.
