Spotting a lizard darting across a sunny rock in the Ozarks or scurrying along a porch railing in Little Rock is a common experience for Arkansas residents, yet most people can only name one or two species. Fifteen lizard species call the state home, and understanding the types of lizards in Arkansas helps homeowners, hikers, and backyard naturalists tell a harmless native skink from a fast-spreading introduced gecko.
Fifteen lizard species live in Arkansas. 13 of them are native to the state, while the other two ā the Mediterranean house gecko and the brown anole ā are exotic lizards brought to Arkansas as a result of human activity.
None of them pose a venom threat to people or pets. There are no poisonous lizards in Arkansas. This guide walks through nine of the most recognizable species found across the state, covering how to identify each one, where it lives, and what makes it stand out from its neighbors.
Pro Tip: Most Arkansas lizards are shy and will flee rather than bite. If you want a closer look, approach slowly and avoid grabbing the tail, since several species can drop it as an escape tactic.
1. Western Slender Glass Lizard
The western slender glass lizard (Ophisaurus attenuatus attenuatus) is the lizard most likely to fool someone into thinking they have found a snake. The legless lizard, the western slender glass lizard, is often mistaken for a snake. The giveaway is in the details rather than the overall body shape.
Look closely and the differences become obvious. This lizard can be told apart from a snake because it has eyelids and ear openings, which snakes do not. Its common name comes from a defensive trick shared with true glass: its tail can break off easily if it’s caught, helping it escape from predators, and the tail can then grow back later. This species turns up in grasslands and open woodlands statewide, and it shares habitat preferences with several snake species found across Arkansas that are frequently confused with it at a glance.
2. Green Anole
The green anole (Anolis carolinensis) is arguably the most familiar lizard in the Southeast, prized for its ability to shift between bright green and brown depending on temperature and mood. Males announce their presence with a colorful throat fan. Green anoles and other species of anoles have dewlaps, colorful throat fans they can extend to communicate, a feature that makes them look a bit like tiny dinosaurs.
Arkansas residents sometimes worry about confusing this native species with an invasive look-alike, but the risk is fairly low. Cuban Green Anoles in Arkansas have a limited range, so if you find a Green Anole, it’s most likely native. True green anoles favor trees, shrubs, and garden vegetation, where their coloring helps them disappear against leaves. Anyone curious about how this species compares to lizards kept in captivity can check this overview of popular pet reptile species for context on care and temperament differences between wild and captive-bred anoles.
3. Eastern Collared Lizard
Few Arkansas reptiles draw as much attention as the eastern collared lizard (Crotaphytus collaris). It is the most colorful and regal of the Arkansas lizards, a common species found in exposed rock outcroppings throughout most of the Interior Highlands. The species gets its name from a pair of dark bands around the neck.
Physical traits make it easy to pick out on a rocky glade. This lizard has a large, broad head and chunky body with a round tail, with two dark collars on the neck, a thinner one near the head and a thicker one near the body, and coloring that is variable: greenish-blue, olive, brown, or yellow. Eastern Collared Lizards can be found in northwestern Arkansas in desert shrubland, open juniper-pinon forest, and grassland, where they prefer areas with rocks for basking, open space for running, and lots of sunlight.
Males are notoriously territorial. Adult males will not live in the same area, and if they’re placed in the same enclosure, they’ll fight to the death, often displaying dominance by standing on their hind legs, inflating their throat, and weaving from side to side.
Important Note: This species has declined sharply across its Arkansas range. According to the U.S. Forest Service, the Eastern collared lizard was once prevalent across the Ozarks 40-50 years ago, and is now considered a species of greatest conservation need in the state. Researcher Casey Brewster of the University of Arkansas noted that somewhere between 70-80% of our populations have disappeared in the past 40-50 years, largely tied to the loss of the periodic fires that once maintained open, rocky glade habitat.
4. Texas Horned Lizard
The Texas horned lizard (Phrynosoma cornutum) looks like a small, spiky dragon, and its unusual armor is not just for show. Texas Horned Lizards are found in western Arkansas in open, sandy land without much plant life. Its range in the state is limited compared to more widespread species like the prairie lizard or five-lined skink.
The horns aren’t the only defense this species carries. In addition to the two long central horns, two rows of spiky scales, called fringe scales, line the sides of the body. When seriously threatened, it has one more trick. These reptiles are even able to aim the foul-tasting blood directly into the predator’s mouth, talk about biting off more than you can chew. Anyone who has spent time watching horned lizards in the American Southwest will recognize the family resemblance; this species-in-decline story mirrors what has happened with several lizard species native to Texas, where habitat loss has similarly shrunk populations.
5. Common Five-Lined Skink
The common five-lined skink (Plestiodon fasciatus) is one of six skink species found in Arkansas, and it is among the easiest to recognize thanks to the bright stripes running down its back. Skinks are among the most common lizards; there are six different species of skinks that share several features.
Skinks share a set of family traits that separate them from anoles and fence lizards:
- Shiny, smooth scales rather than rough or spiny texture, as all have shiny, smooth scales and possess tails that easily break when handled
- A fast, low, snake-like crawl through leaf litter
- A preference for hiding under logs, rocks, and loose bark
- Juveniles with brighter, more electric-blue tails than adults
Young five-lined skinks display a strikingly bright blue tail that fades to gray as they mature, a trait that likely helps redirect predator attacks away from the vital body. Gardeners in the region who want to compare this species with lizards found in neighboring states can review this guide to lizard species in Tennessee, where several of the same skink species overlap.
6. Little Brown Skink
The little brown skink (Scincella lateralis) is easy to overlook, and that is precisely the point. That’s a very handy adaptation for one of the smallest reptiles in Arkansas. Its small size and drab coloring let it slip through leaf litter almost unnoticed.
Being tiny comes with tradeoffs, since this skink sits fairly low on the local food chain. The Little Brown Skink has many predators, including snakes, larger lizards, and birds of prey, and when they try to sneak up on a “sleeping” Little Brown Skink, often the skink can run away using the element of surprise. Homeowners who find these skinks under mulch or garden stones can generally leave them alone, since they help control small insect pests. For a look at other small arthropod predators sharing the same leaf-litter habitat, this breakdown of centipede species in Arkansas covers a group that competes for some of the same prey.
7. Prairie Lizard
The prairie lizard (Sceloporus consobrinus) belongs to the spiny lizard family, a group defined by rough, keeled scales that give the skin a slightly bristly texture. The Texas horned lizard and prairie lizard represent the spiny lizard family; the western slender glass lizard is a legless species living in Arkansas.
This species is one of the most widely distributed lizards in the state, favoring open, sun-exposed ground rather than deep woods. Most of Arkansas’ native lizards inhabit the prairie lands throughout the state. Fence posts, rock piles, and dead logs at the edge of open fields are typical basking spots. Its gray-brown, mottled coloring provides camouflage against bark and stone, making it one of the harder species to spot despite being common.
8. Mediterranean House Gecko
The Mediterranean house gecko (Hemidactylus turcicus) is one of only two lizard species in Arkansas that did not arrive naturally. The Mediterranean house gecko and the brown anole are exotic lizards brought to Arkansas as a result of human activity. Its pale, translucent skin and large, lidless eyes make it easy to distinguish from any native species in the state.
Unlike Arkansas’s native diurnal lizards, this gecko is almost exclusively nocturnal, and it has adapted well to buildings. It is most often seen clinging to exterior walls near porch lights, where it picks off moths and other insects drawn to the glow. Its sticky toe pads let it climb smooth vertical surfaces that would stop any native Arkansas lizard cold. Readers interested in how introduced gecko species have spread through other states can compare notes with this guide to lizard species found in Florida, where several similar non-native geckos have established large populations.
9. Brown Anole
The brown anole (Anolis sagrei) is the second introduced species on this list, and it has a reputation for outcompeting native green anoles wherever the two overlap. The brown anole lizard, also called the Cuban brown anole, is light brown with dark brown markings on its back, along with light color lines on the sides.
Males can grow noticeably larger than their green anole counterparts. The dewlap ranges in color from bright orange or red to yellow, and males grow to around eight inches in total length. Because brown anoles are ground-dwelling and aggressive toward green anoles, homeowners who notice green anole numbers dropping in a yard sometimes find an expanding brown anole population is the reason. The species has spread widely through the southeastern United States, following a pattern similar to lizard introductions documented in this overview of lizard species in Arizona, where non-native reptiles have likewise established footholds in urban areas.
| Species | Status in Arkansas | Typical Habitat |
|---|---|---|
| Western Slender Glass Lizard | Native | Grasslands, open woodlands |
| Green Anole | Native | Trees, shrubs, gardens |
| Eastern Collared Lizard | Native (declining) | Rocky glades, Interior Highlands |
| Texas Horned Lizard | Native (limited range) | Open sandy ground, western Arkansas |
| Common Five-Lined Skink | Native | Leaf litter, under logs |

| Prairie Lizard | Native | Open fields, fence posts, rock piles |
| Mediterranean House Gecko | Introduced | Buildings, exterior walls |
| Brown Anole | Introduced | Ground cover, urban yards |
Whether a lizard is basking on a limestone bluff in the Ozarks or clinging to a porch screen in Fayetteville, most Arkansas species pose no threat and fill useful roles controlling insect populations. Learning to recognize the nine species covered here, along with the six other skinks and racerunners rounding out the state’s fifteen species, turns a quick backyard glimpse into a genuine identification.
