how long do lizards live
Lizards can live anywhere from just a few years to over 40 years, depending mostly on their species and whether they live in the wild or in captivity.
Quick Scoop
- Many wild lizards average around 5 years because of predators, disease, and harsh conditions.
- Common pet lizards (like geckos and bearded dragons) often live 10–20 years with good care.
- Some large species, like iguanas , can reach about 20 years.
- Komodo dragons can live around 30–40 years , especially in captivity.
- A close reptile relative, the tuatara (not technically a lizard) can live well over 100 years.
Typical Lifespans by Type
| Lizard (or relative) | Typical lifespan | Notes |
|---|---|---|
| Small geckos / house geckos | About 10–15 years | [7][3][5]Common in homes and as pets. |
| Chameleons | About 5–7 years | [5][7]Generally shorter-lived than many other pet lizards. |

| Iguanas | Up to ~20 years or more | [7][5][3]Large lizards that need big, well-managed enclosures. |
| “Average” pet lizard | Roughly 10–15 years | [9][3]Most common species fall somewhere in this range. |

| Tuatara (close relative) | Well over 100 years | [5]Not a true lizard but often mentioned in longevity discussions. |
Why the Range Is So Big
Several factors shape how long lizards live.
- Species and genetics: Each species has a built‑in “expected” lifespan.
- Wild vs. captivity: Predators, injuries, and food shortages shorten wild lifespans; safe enclosures and steady food can extend them to decades.
- Diet and environment: Proper temperature, humidity, hiding places, and nutrition significantly boost longevity in pets.
If You’re Thinking About a Pet Lizard
If you’re considering a lizard, it’s realistic to plan for 10–20 years of care for popular species like leopard geckos or bearded dragons, assuming good husbandry and veterinary support.
TL;DR: “How long do lizards live?” Most common lizards live around 5 years in the wild and roughly 10–20 years as pets, with a few giants reaching 30–40 years or more.
