Green Anole (Anolis carolinensis)
The Green Anole is one of the most recognizable lizards in Arkansas, known for its vibrant green coloration and ability to change to brown to blend into its surroundings. Typically measuring around 5 to 8 inches long, they thrive in gardens, shrubs, and tree branches, especially in warm, sunny areas. Their dewlap, a colorful flap of skin under the chin, is often displayed during territorial disputes or courtship displays, making them a fascinating species to observe.
Six-lined Racerunner (Aspidoscelis sexlineata)
The Six-lined Racerunner is a slender, fast-moving lizard characterized by six distinct black lines running down its tan or brown body. Reaching lengths of up to 10 inches, it is often seen darting across sandy or rocky areas, especially in open habitats like prairies and fields. Its quick movements and striking pattern make it a favorite among wildlife watchers and photographers.
Southern Fence Lizard (Sceloporus undulatus)
The Southern Fence Lizard is a robust, spiny lizard commonly found basking on rocks, fences, and tree trunks. It measures approximately 5 to 8 inches and is notable for its rough, keeled scales and vibrant blue patches on its belly and throat, especially during the breeding season. Their territorial behavior and ease of observation make them a popular species for those interested in herpetology.
Broad-headed Skink (Plestiodon laticeps)
The Broad-headed Skink is one of Arkansas’s largest lizards, growing up to 13 inches long. It features a robust body, a broad head, and a shiny, smooth scale pattern. Often found in wooded areas and leaf litter, this skink is a ground dweller that prefers moist habitats. Its striking coloration and size make it a remarkable sight for those exploring Arkansas’s forested regions.
Coal Skink (Plestiodon anthracinus)
The Coal Skink is a small, dark lizard measuring about 4 to 6 inches, with a shiny black or dark brown body and bright orange or yellow tail. It prefers moist, shaded environments such as leaf litter, logs, and rocky outcroppings. Its secretive nature often requires close observation to spot, making it a rewarding find for dedicated herpetologists.
Slender Glass Lizard (Ophisaurus attenuatus)
Despite its snake-like appearance, the Slender Glass Lizard is a legless lizard, reaching lengths of up to 3 feet. It has a long, slender body with a smooth, shiny scale pattern, and it can shed its tail to escape predators. Found in grassy fields and open woodlands, this species is fascinating due to its limbless form and elusive behavior.

It typically measures around 6 inches and displays a mix of brown, gray, and green coloration with distinctive markings. Its ability to thrive in disturbed habitats makes it a notable species for urban wildlife enthusiasts.
Green Tree Lizard (Lepidophyma flavivittatum)
While more common in southern parts of the U.S., the Green Tree Lizard can be found in some southern Arkansas regions. It’s a small, agile lizard that prefers arboreal habitats, often seen clinging to trees and shrubs. Its bright green coloration and active behavior make it a delightful species for those exploring the state’s forested areas.
Texas Alligator Lizard (Gerrhonotus infernalis)
