Louisiana’s diverse habitats—from swamps and wetlands to forests and urban areas—are home to a fascinating variety of lizard species. Whether you’re a nature lover, a budding herpetologist, or a homeowner curious about local wildlife, understanding the different types of lizards in Louisiana can enhance your appreciation of the state’s rich biodiversity. This guide covers ten common and notable lizard species found across Louisiana, providing detailed descriptions, habitat preferences, and tips for identification.
Green Anole (Anolis carolinensis)
The Green Anole is one of Louisiana’s most recognizable lizards, often called the American chameleon due to its ability to change color from bright green to brown. Typically measuring around 5 to 8 inches, this lizard thrives in trees, shrubs, and gardens, making it a common sight in residential yards. Its dewlap, a colorful flap of skin beneath the chin, is used for territorial displays and attracting mates, making it a fascinating species to observe up close.
Six-lined Racerunner (Aspidoscelis sexlineata)
The Six-lined Racerunner is a slender, fast-moving lizard characterized by six distinctive black lines running lengthwise down its tan or brown body. Usually reaching 7 to 10 inches, it prefers open, sandy areas, often found in pine forests and grasslands. Its speed and agility help it escape predators, and it primarily feeds on insects, making it an important part of the local ecosystem.
Southern Fence Lizard (Sceloporus undulatus)
This hardy lizard is easily identified by its rough, spiny scales and the characteristic blue patch on its throat and belly, especially prominent in males. Typically 4 to 8 inches long, the Southern Fence Lizard favors rocky outcroppings, fences, and wooded areas. Its territorial behavior and distinctive markings make it a favorite among wildlife watchers in Louisiana’s parks and backyards.
Common Five-lined Skink (Plestiodon fasciatus)
The Five-lined Skink is a vibrant lizard with five bright yellow or white lines running from its head to its tail, which can grow up to 8 inches. Juveniles display a striking blue tail, which fades as they mature. Found in leaf litter, logs, and brush piles, this skink plays a vital role in controlling insect populations and is often encountered in gardens and forests throughout Louisiana.
Broad-headed Skink (Plestiodon laticeps)
One of Louisiana’s largest skinks, the Broad-headed Skink can reach lengths of 14 inches and is distinguished by its broad head and robust body. Its coloration varies from brown to olive and features a yellow or orange stripe along the sides. Preferring wooded areas with ample cover, this species is a semi-arboreal predator that feeds on insects, snails, and small invertebrates.
Green Tree Monitor (Varanus prasinus) — Note: Not native but sometimes kept as pets
While not native to Louisiana, some Green Tree Monitors are kept by reptile enthusiasts in captivity. They are arboreal lizards with striking green coloration and a long, prehensile tail. Their presence in local pet trade influences sightings, but they are not naturally occurring in Louisiana’s wild habitats. This species is highly active and requires specialized care, making it a species for experienced herpetologists.
Slender Glass Lizard (Ophisaurus attenuatus)
The Slender Glass Lizard resembles a snake but is actually a legless lizard. It can grow up to 3 feet long and is characterized by its smooth, shiny scales and a long, tapering tail. Its camouflage—often blending with leaf litter and grass—helps it evade predators. It feeds mainly on insects and small invertebrates and is often found in grassy fields, prairies, and open woodlands.
Southern Thicktail (Barbaturex brunnea)
A lesser-known species, the Southern Thicktail is a robust lizard measuring about 8 inches, with a thick tail and a sturdy body. Its coloration varies from brown to reddish, and it prefers rocky or brushy habitats. Due to its secretive nature, sightings are rare, but it plays a role in controlling insects and small invertebrates in its environment.
Texas Spiny Lizard (Sceloporus olivaceus)
Although originally more common in Texas, the Texas Spiny Lizard has established populations in southern Louisiana. It features a spiny, rough-scaled body, usually with a greenish or brown coloration, and can grow up to 9 inches long. It prefers rocky hillsides, forest edges, and urban parks, often basking in the sun on logs or fences.
How to Choose
When selecting a lizard for observation or care, consider habitat preferences, size, and activity level. If you’re interested in a species that is easy to spot in yards or parks, the Green Anole or Fence Lizard are great options. For those interested in larger or more colorful species, the Broad-headed Skink offers impressive size and markings. Always prioritize species that are native or sustainable to observe in the wild and ensure you follow local wildlife regulations if considering keeping a lizard as a pet.
