Quick answer
Green Iguanas (Iguana iguana) typically live around 10–15 years, longer in captivity. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Key takeaway
Green Iguanas (Iguana iguana) typically live around 10–15 years, longer in captivity. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Green Iguana lifespan in the wild
Field and museum records place most green iguanas near 10–15 years, longer in captivity. That figure blends ages at death across regions, so treat it as a planning range. Body size (about 5 kg) and risk lifestyle both shape the average.
What shortens green iguana lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever green iguanas share landscapes with people.
What helps green iguanas live longer
Connected habitat, low chronic stress, and reliable food support longevity. For captive or domestic relatives, species-correct diet and veterinary screening matter more than generic “pet” advice.
Green Iguana life stages
Juveniles usually face higher mortality than prime adults. Older animals may move less, show dental wear, or lose body condition — useful signs when ageing green iguanas in the field.
Habitat and range
Green iguanas are native to a wide band of the Americas, from Mexico and Central America through much of tropical South America, usually near rivers and lakes. They have also been introduced to places such as Florida and several Caribbean and Pacific islands, where they can become invasive. They favor warm, humid lowland forest.
As a pet
Green iguanas are widely sold as pets but are challenging to keep well. They grow large, need spacious enclosures with strong UVB lighting, high humidity, and warm basking areas, and can deliver painful scratches, bites, and tail whips if stressed. Many are surrendered when owners underestimate their size and care needs.
