Which big lizards live in Georgia
In Georgia, the largest lizards residents regularly encounter are adult green anoles and introduced Caribbean brown anoles, often reaching 8 to 10 inches snout-to-vent. Native species such as the broad-headed skink and eastern fence lizard can grow larger, while occasional reports of much bigger lizards usually trace to nonnative tegus or released pets like iguanas. This guide covers identification, behavior, habitat, risks, and humane management for the big lizards most likely to appear in Georgia yards, gardens, and neighborhoods.
Key species overview
Green anole (Anolis carolinensis)
The most familiar large lizard in Georgia, often called the American chameleon for color shifts between green and brown. Adults commonly reach 6 to 8 inches, with a long tail, pink throat fan in males, and climbing ability on walls and trees. Often seen on porches and in gardens, they feed on insects and are generally shy around people.
Carolina anole (same species, regional name)
No biological distinction; refers to the same green anole across the Southeast, adapted to yards, farmland edges, and urban settings throughout Georgia.
Broad-headed skink (Plestiodon laticeps)
One of the largest native lizards in Georgia, adult males with broad jaws and large orange heads. Juveniles are dark with light stripes; adults can exceed 12 inches total length. They forage under debris and logs, eat insects and other small prey, and favor mature hardwood edges.
Eastern fence lizard (Sceloporus undulatus)
Medium-sized and common in forest edges and yards, adults reach 5 to 7 inches. Known for quick, darting runs and keeled scales. Important prey for birds and snakes, they help regulate insect populations.
Introduced and occasional species
Caribbean brown anole has spread across the state, often outnumbering greens but remaining similarly sized. Rare reports of tegus and iguanas stem from released pets; tegus can grow very large but are not established breeding populations in Georgia.
Identification tips and key facts
Use color, size, pattern, and behavior to identify big lizards in Georgia.
- Green anole: slender, long tail, dewlap in males, color changes with mood and temperature.
- Broad-headed skink: heavy body, large head, in life males have orange head and jaw; juveniles striped.
- Eastern fence lizard: keeled scales, quick side-to-side running, less flashy throat color.
- Caribbean brown anole: similar to green anole but often darker, more aggressive toward greens.
- Iguanas and tegus: unlikely to be breeding, usually released pets; tegus can exceed 4 feet and are strong diggers.
| Attribute | Verified Detail | Source Type |
|---|---|---|
| Typical adult size (green anole) | 6–8 inches snout-to-vent; total length to 10–12 inches | Field guides and herpetological references |
| Typical adult size (broad-headed skink) | Up to 12 inches total length; robust body and large head | Regional herpetology resources |
| Caribbean anole presence | Established across much of Georgia, often in urban and suburban areas | Recent distribution surveys |
| Established breeding tegus in Georgia | No confirmed breeding populations; occasional captures suggest releases or transient individuals | Wildlife agency records |
| Iguana establishment in Georgia | Not established; reports involve released or escaped pets with limited survival in colder areas | Wildlife agency and research notes |
Habitat and where you’ll find them
Green anoles inhabit yards, gardens, fence lines, and tree trunks, favoring sunny spots with cover nearby. Broad-headed skinks prefer wooded edges, rock piles, and logs where they can shelter and forage. Eastern fence lizards occur in forest openings, fence posts, and brushy areas. Introduced brown anoles now occupy many suburban habitats, often outcompeting greens in direct encounters.
Behavior and daily patterns
Most large lizards in Georgia are diurnal, warming in the sun in the morning and hunting through the day. Anoles and skinks are agile climbers and frequent vertical surfaces. Males defend territories with displays, head-bobs, and push-ups. While generally nonaggressive, they may bite if handled. Tegus are more powerful diggers and foragers but remain uncommon and are not known to breed in the state.
Risks, disease, and myths
Big lizards are not a major public health threat; they rarely carry diseases that affect humans and more often help by reducing insects. Salmonella risk is low with basic hygiene, such as washing hands after handling. Myths exaggerate aggression; anoles and fence lizards display threat postures but prefer to flee. In Georgia, no native lizards are venomous, and the strongest danger is from frightened pets lashing with tails.
Humane management and deterrence
To manage large lizards humanely, reduce ground clutter and debris where they hide, secure trash, and keep outdoor lights off at night to limit insects they eat. Exclude skinks from foundations with tight-fitting screens and seal gaps near doors. Avoid relocating lizards long distances, as this is stressful and often ineffective. If a tegu or large nonnative is repeatedly seen, contact local wildlife authorities for safe removal guidance.
When to call professionals
For repeated tegu sightings, concerns about very large lizards, or safe handling of nonnative species, reach out to Georgia Department of Natural Resources or a permitted wildlife control operator. Routine anoles, skinks, and fence lizards do not require removal and can be left alone to perform insect control.
