29 Types of Lizards in Texas (And How to Identify Each One)
November 7, 2026
Texas has more lizard species than almost any other state in the country, and most of them go unnoticed in backyards, rock piles, and roadside ditches every single day. From the spiky, blood-squirting horned toad to a tiny gecko that squeaks when it’s frightened, the types of lizards in Texas range from desert specialists in the Trans-Pecos to tree-dwelling anoles in piney East Texas gardens.
None of these species pose a real threat to people or pets, which sets them apart from some of the state’s venomous animals in Texas. What follows is a species-by-species look at the 29 lizards most commonly reported across the Lone Star State, with the physical traits, habitat preferences, and behaviors that make each one identifiable in the field.
1. Texas horned lizard
The Texas horned lizard (Phrynosoma cornutum) is the state’s most recognizable reptile and has carried the title of official state reptile since 1993. The Texas Horned Lizard was adopted as the Texas state reptile on June 18, 1993. Most Texans know it by its nickname, the “horny toad,” even though it is not an amphibian at all.
The Texas horned lizard is typically 2½ to 4 inches long and has a short, pointed snout, a broad, flat body, and a short tail, with a prominent crown of spines at the back of its head. Two rows of spiny scales run down each side of its body, which separates it from Texas’s other horned lizard species. When threatened, it can puff itself up and, famously, squirt blood from ducts near its eyes to deter predators.
Texas horned lizards feed primarily on harvester ants, also called red ants. That dependence has become a problem: the decline in the species has been linked to red imported fire ants, which are thought to out-compete native harvester ants for food and space. Because of this decline, the Texas horned lizard was one of the first species listed by Texas as threatened, on July 18, 1977.
Important Note: Because the Texas horned lizard is a state-threatened species, it is illegal to collect, handle, or keep one found in the wild. Observe and photograph them, but leave them exactly where you find them.
2. Round-tailed horned lizard
The round-tailed horned lizard (Phrynosoma modestum) is the smallest and plainest-looking of the three horned lizard species native to Texas. Unlike the Texas horned lizard, it lacks rows of enlarged spiny scales along its sides, and its horns are reduced to small, blunt bumps rather than a crown of spines. That stripped-down appearance, paired with its gray or tan coloring, makes it blend almost perfectly into the gravelly desert flats of the Trans-Pecos and far West Texas.
This species favors sparse, rocky terrain with little vegetation, often alongside creosote and yucca. Like its larger cousin, it relies on camouflage and a flattened, motionless posture rather than speed to avoid predators. Its range extends south into the deserts of northern Mexico, where related horned lizard species also occur.
3. Green anole
The green anole (Anolis carolinensis) is the only anole species native to the United States and one of the most familiar lizards in East and Central Texas gardens. It can shift between bright green and brown depending on temperature, mood, and background, a trait that has earned it the inaccurate nickname “American chameleon.”
Males display a pink throat fan, called a dewlap, which they extend during territorial disputes and courtship. Green anoles are strong climbers and spend most of their time on fences, shrubs, and tree trunks hunting small insects. Populations have shrunk in some urban areas where the introduced brown anole has moved in and claimed the same ground-level perches.
4. Brown anole
The brown anole (Anolis sagrei) arrived in the United States from Cuba and the Bahamas and has since spread through much of the Gulf Coast, including large parts of urban and suburban Texas. It has a mottled brown-and-gray body, a ridged tail, and an orange-red dewlap edged in yellow, which distinguishes it from the native green anole at a glance.
Unlike the green anole, this species rarely changes color and spends more time low to the ground than in the canopy. It is also more aggressive, often displacing green anoles from prime basking spots in yards and parks. Because it cannot survive hard freezes well, its range in Texas is concentrated in the warmer southern and coastal counties.
5. Texas spiny lizard
The Texas spiny lizard (Sceloporus olivaceus) is one of the most frequently seen lizards in the state, and for good reason. It is native to the south-central United States and is one of the most commonly seen lizards in Texas, often found in trees or on fences. It has strongly keeled, spiny dorsal scales that give it a rough texture, along with gray-brown to olive coloration with darker crossbands that provide excellent camouflage on bark.
Texas spiny lizards are abundant fence- and tree-dwelling reptiles whose diurnal activity and visible displays make them conspicuous residents of yards and parks. Males perform rapid push-ups to defend territory and attract mates, revealing blue patches along the belly in the process. When approached, they typically dash around the far side of a trunk or post rather than fleeing outright, a behavior that makes them easy to spot but hard to photograph.
6. Blue spiny lizard
The blue spiny lizard (Sceloporus cyanogenys) is a larger, more strikingly marked relative of the Texas spiny lizard, limited in the United States to the Rio Grande Valley and a handful of South Texas counties. Males develop a bold blue-black throat and belly, visible even at a distance, while females stay a duller gray-brown.
This species favors tree trunks, rock walls, and building exteriors, where it basks in full sun before retreating into crevices. Its range extends much further into eastern Mexico than it does into Texas, making the state’s population something of a northern edge outpost. It shares the same spiny, keeled scales found throughout the Sceloporus genus.
7. Crevice spiny lizard
The crevice spiny lizard (Sceloporus poinsettii) is built for exactly the habitat its name suggests. It has a noticeably flattened body that lets it wedge into narrow rock cracks when threatened, a defense strategy shared with several other crevice-dwelling reptiles. Its tail is marked with dark bands, and its body is covered in large, keeled scales that give it a rugged, armored look.
This species is restricted to the rocky canyons and limestone outcrops of the Trans-Pecos region, where boulder fields and cliff faces provide constant access to escape routes. It feeds on insects and spiders encountered while basking near crevice entrances, rarely straying far from the safety of a retreat.
8. Rose-bellied lizard
The rose-bellied lizard (Sceloporus variabilis) is a small, ground-dwelling spiny lizard found in the brushlands and thorn scrub of South Texas. Males develop the rosy-pink belly patches that give the species its common name, bordered by black along the outer edges of the abdomen.
Unlike many of its Sceloporus relatives, which favor trees and fence posts, the rose-bellied lizard spends most of its time on the ground among leaf litter and low vegetation. Its rough, keeled scales and mottled brown coloring provide effective camouflage against sandy soil and dry brush, and it remains active through much of the year in the mild South Texas climate.
9. Prairie lizard
The prairie lizard (Sceloporus consobrinus) was once lumped together with the eastern fence lizard as a single wide-ranging species before researchers split the group based on genetic differences. It is a gray-to-brown lizard with faint dorsal stripes, closely resembling other fence lizards found throughout Central and North Texas.
It is a habitat generalist, turning up on fence posts, tree trunks, wood piles, and rocky outcrops across grasslands and woodland edges. Males show blue patches along the throat and belly during the breeding season. Because it overlaps so much in appearance and range with other spiny lizards, careful attention to geography is often the easiest way to confirm an identification.
10. Eastern collared lizard
The eastern collared lizard (Crotaphytus collaris) is one of the most colorful lizards found in Texas, with males showing a vivid green or yellow-green body set off by two bold black collar bands around the neck. Females are more subdued but develop orange markings along the sides when carrying eggs.
This species is strongly associated with the rocky outcrops and limestone glades of the Hill Country and Edwards Plateau, much of which overlaps with prime habitat for deer in Texas. Collared lizards are known for an unusual escape tactic: when sprinting at full speed, they can rear up and run on their hind legs alone, using the tail for balance.
11. Greater earless lizard
The greater earless lizard (Cophosaurus texanus) lacks visible external ear openings, a trait shared by several related species across the state. Its most distinctive behavior is tail movement: it curls its long tail upward over its back and wags it side to side, a display thought to confuse predators or signal fitness to rivals.
This lizard favors open, sunbaked ground in West and Central Texas, including sandy washes, gravel flats, and rocky streambeds. It is an exceptionally fast sprinter, relying on speed rather than camouflage once spotted, and is most active during the hottest part of the day when few other animals are moving.
12. Texas earless lizard
The Texas earless lizard refers to the nominate subspecies, Cophosaurus texanus texanus, found across the eastern portion of the greater earless lizard’s range, including the Hill Country and Edwards Plateau. It shares the same ear-less head structure and upward-curling, wagging tail display as other populations of the species.
Compared to western populations of the greater earless lizard, Texas earless lizards tend to show slightly lighter dorsal banding that blends with the pale limestone soils common across Central Texas. They occupy the same type of open, rocky, sun-exposed ground and are often seen darting across hiking trails before vanishing into cover.
13. Lesser earless lizard
The lesser earless lizard (Holbrookia maculata) is smaller and plainer than its “greater” relative, lacking the bold black bars often visible beneath the tail of Cophosaurus species. It has a pale, sandy coloration with faint rows of dark spots down the back, suited perfectly to the loose, sandy soils of the High Plains and Panhandle.
This species does not perform the same dramatic tail-curling display as the greater earless lizard, instead relying almost entirely on speed and camouflage to avoid predators. It is most active in open prairie and shortgrass habitat with minimal vegetation, where it can be seen darting between patches of bare ground.
14. Keeled earless lizard
The keeled earless lizard (Holbrookia propinqua) takes its name from its distinctly keeled, or ridged, body scales, a texture that separates it from the smoother-scaled lesser earless lizard. It is a small, fast-moving species adapted to loose, shifting sand.
This lizard is concentrated along the barrier islands and coastal dunes of South Texas, including beach habitat that overlaps with nesting and foraging grounds for many water birds in Texas. Its pale coloration matches the bright sand of Gulf Coast beaches, and it is well adapted to the heat and instability of a constantly shifting dune environment.
Key Insight: The four earless lizard species in Texas share the same missing ear opening, but their tail behavior, scale texture, and preferred soil type offer the fastest way to tell them apart in the field.
| Species | Scale Texture | Preferred Habitat |
|---|---|---|
| Greater Earless Lizard | Smooth to slightly rough | Open gravel flats, West and Central Texas |
| Texas Earless Lizard | Smooth, lighter banding | Hill Country, Edwards Plateau |
| Lesser Earless Lizard | Smooth, pale sandy tone | Shortgrass prairie, High Plains |
| Keeled Earless Lizard | Distinctly keeled/ridged | Coastal dunes, barrier islands |
15. Common side-blotched lizard
The common side-blotched lizard (Uta stansburiana) is named for the dark blotch found just behind each front leg, a marking that remains visible even as the rest of its coloring varies widely between individuals. It is one of the most heavily studied lizards in North America because of its complex mating system, in which males display one of three throat colors, each tied to a different reproductive strategy.
In Texas, this species is found in the arid Trans-Pecos, favoring open desert flats, washes, and scrubland with loose soil for burrowing. It is small, fast, and short-lived, often completing its entire life cycle within a single year in harsher desert conditions.
16. Tree lizard
The tree lizard (Urosaurus ornatus) is a small, flattened lizard built for life on vertical surfaces, from tree bark and canyon walls to the sides of buildings. Its body color shifts between gray, brown, and olive tones to match whatever surface it is resting on, and a patch of enlarged scales on its back, mixed among smaller granular scales, helps separate it from other small lizards sharing its range.
Males show blue patches on the belly and throat, visible mainly during territorial standoffs. In Texas, the species is concentrated in the canyons and rocky uplands of the Trans-Pecos, where it forages for small insects along cracks and crevices throughout the day.
17. Long-nosed leopard lizard
The long-nosed leopard lizard (Gambelia wislizenii) is a powerful, large-headed predator among Texas’s smaller lizards, named for the dark leopard-like spots scattered across its pale body. Unlike most of the state’s lizards, which feed almost exclusively on insects, this species regularly eats other lizards, using its strong jaws to subdue prey nearly its own size.
It occupies the open desert flats of far West Texas, where sparse vegetation provides little cover and speed becomes essential for both hunting and escaping predators. It hunts using a sit-and-wait strategy, remaining motionless before bursting into a fast sprint to chase down prey or flee danger.
18. Six-lined racerunner
The six-lined racerunner (Aspidoscelis sexlineata) is named for the six pale stripes that run the length of its dark body, a pattern that makes it one of the easier whiptail-type lizards to identify. It is also one of the fastest lizards in North America relative to its size, capable of short bursts of speed that make it nearly impossible to catch by hand.
This species is a widespread, active forager found across most of Texas, from open woodlands to suburban yards, where it searches leaf litter and loose soil for insects and spiders detailed in guides to insects in Texas. Unlike ambush predators, racerunners spend most of daylight hours constantly moving, flicking their tongues to track prey by scent.
19. Texas spotted whiptail
The Texas spotted whiptail (Aspidoscelis gularis) combines pale longitudinal stripes with rows of light spots in the darker bands between them, a pattern distinct from the plain stripes of the six-lined racerunner. It is one of the most commonly encountered whiptails in Central and South Texas gardens, parks, and woodland edges.
Like other whiptails, it is an active, all-day forager that relies on scent as much as sight to locate prey, including small caterpillars documented in field guides to butterflies in Texas. Its long, whip-like tail accounts for roughly two-thirds of its total body length and can be shed if grabbed by a predator.
20. Common spotted whiptail
The common spotted whiptail, typically identified in Texas as the marbled whiptail (Aspidoscelis marmorata), shows light spots scattered across a darker background rather than the continuous pale stripes seen on the Texas spotted whiptail. This pattern provides strong camouflage against the mottled gravel and caliche soils of the Trans-Pecos and far West Texas.
Like its whiptail relatives, it forages constantly through the day, hunting insects and occasionally moths cataloged among moths in Texas. Populations of this species are all female in some regions, reproducing through parthenogenesis, a trait documented in several whiptail species across the arid Southwest.
| Species | Pattern | Primary Range |
|---|---|---|
| Six-Lined Racerunner | Six continuous pale stripes | Statewide |
| Texas Spotted Whiptail | Stripes with spots between bands | Central and South Texas |
| Common (Marbled) Spotted Whiptail | Scattered spots, no continuous stripes | Trans-Pecos, West Texas |
21. Great Plains skink
The Great Plains skink (Plestiodon obsoletus) is the largest skink species found in Texas, with adults sometimes reaching more than a foot in length. Its smooth, shiny scales are arranged in a pattern of dark-edged rows that fade with age, while juveniles display a bright blue tail that gradually darkens as they mature.
This species favors grasslands and rocky hillsides across much of Central and North Texas, where it hunts beetles and other invertebrates covered in guides to beetles in Texas. It is a strong burrower, often found beneath rocks, logs, and debris rather than basking in the open like many of the state’s spiny lizards.
22. Five-lined skink
The five-lined skink (Plestiodon fasciatus) is best known for its juvenile coloring: jet-black skin marked with five cream-colored stripes and a strikingly bright blue tail. As the lizard matures, both the stripes and the blue tail color fade, leaving adults a more uniform olive-brown.
In Texas, this species is concentrated in the moister forests of the eastern part of the state, favoring leaf litter and rotting logs similar to habitat shared with several salamanders in Texas. Its smooth, glossy scales and secretive habits often lead people to briefly mistake it for a small, legged amphibian before noticing its clearly reptilian scales.
23. Little brown skink (Ground skink)
The little brown skink, also called the ground skink (Scincella lateralis), is one of the smallest and most overlooked lizards in Texas, rarely growing past a few inches long. Its smooth, glossy, golden-brown scales and secretive, ground-hugging habits make it easy to miss even in areas where it is abundant.
This species lives almost entirely within leaf litter and moist ground cover in East and Central Texas woodlands, hunting tiny invertebrates similar to the prey covered in guides to stink bugs in Texas. Rather than climbing or basking openly, it moves in quick, snake-like undulations through debris, staying hidden from both predators and casual observers.
24. Texas alligator lizard
The Texas alligator lizard (Gerrhonotus infernalis) has a long, armored body, short legs, and a distinctive fold of skin running along each side, giving it a look that splits the difference between a lizard and a small crocodilian. Its slow, deliberate movements and elongated shape often cause it to be mistaken for a snake in Texas at first glance.
This species is concentrated in the rocky canyons and juniper-oak woodlands of the Hill Country and Edwards Plateau, where it hides under rocks and leaf litter by day. Despite its tough, armor-plated appearance, it is harmless to people and feeds mainly on insects, snails, and occasionally smaller lizards.
25. Slender glass lizard
The slender glass lizard (Ophisaurus attenuatus) is a completely legless lizard, a fact that regularly leads people to misidentify it as a snake and treat it as one of the dangerous animals in Texas when it is entirely harmless. Two features give it away as a true lizard: movable eyelids and external ear openings, neither of which snakes possess.
Its name comes from an extreme version of tail autotomy; when grabbed, a large portion of the tail can shatter into several pieces, a defense so dramatic it looks as though the animal has broken like glass. This species is found in grasslands and open woodlands across much of the eastern two-thirds of Texas, where it hunts insects and other small invertebrates along the ground.
26. Texas banded gecko
The Texas banded gecko (Coleonyx brevis) is a small, nocturnal species with soft, granular skin rather than the sticky toe pads associated with many other geckos in Texas. Juveniles show bold dark bands across a pale body, a pattern that breaks up into blotches as the lizard matures.
This species is found across the Trans-Pecos and South Texas, where it hides by day beneath rocks and debris, emerging at night to hunt small insects and spiders. When handled or threatened, it produces an audible squeak, an unusual defense among lizards that often startles people who encounter it for the first time.
27. Mediterranean gecko
The Mediterranean gecko (Hemidactylus turcicus) is an introduced species, originally native to the Mediterranean region, that has become one of the most commonly seen types of geckos in Texas around buildings statewide. Its translucent, pinkish-gray skin and large, dark eyes make it easy to spot clinging to walls near porch lights after dark.
Unlike the native Texas banded gecko, this species has specialized sticky toe pads that let it climb smooth vertical surfaces, including glass and stucco. It has thrived in urban and suburban environments by exploiting the insects drawn to outdoor lighting, making it one of the few lizards in the state more often seen at night than during the day.
| Species | Toe Pads | Active Period | Origin |
|---|---|---|---|
| Texas Banded Gecko | None (granular skin) | Nocturnal | Native |
| Mediterranean Gecko | Sticky adhesive pads | Nocturnal | Introduced |
28. Texas night lizard
The Texas night lizard (Xantusia vigilis) belongs to a small, secretive family of lizards rarely encountered by casual observers. It has smooth, granular scales, small eyes, and a flattened body suited to squeezing beneath rocks and decaying yucca and agave debris.
In Texas, this species is restricted to the rocky deserts of the Trans-Pecos, where it remains hidden through the day and emerges briefly at night to feed on small insects. Unlike most Texas lizards, which lay eggs, night lizards give birth to live young, an adaptation that may help offspring survive in the unpredictable desert climate.
29. Northern curly-tailed lizard
The northern curly-tailed lizard (Leiocephalus carinatus) is not native to Texas at all. It originates in the Bahamas and Caribbean, the same region covered in guides to lizards in Jamaica, and was introduced to the southern United States, where isolated populations have since become established in parts of the state.
True to its name, this robust, heavy-bodied lizard carries its tail curled up and forward over its back, a posture unlike any native Texas species. It is a ground-dwelling, sun-loving lizard that forages actively for insects and even small vertebrates, and its presence in Texas remains limited and localized compared to its widespread success in Florida.
Pro Tip: If a lizard in a Texas yard has a tail curled tightly over its back like a scorpion, it is very likely the introduced northern curly-tailed lizard rather than any native species.
Final Thoughts on Texas Lizard Diversity
From the armored, ant-eating horned lizard to geckos that thrive on porch lights, the types of lizards in Texas reflect just how varied the state’s landscapes really are, spanning Gulf Coast dunes, Hill Country canyons, and Trans-Pecos desert flats within a single state line. Every one of these 29 species is harmless to humans, a point worth remembering next to the far more cautious approach warranted around the state’s poisonous animals in Texas.
Readers curious about how Texas compares to other regions can explore related guides covering lizards in Tennessee or the very different lizard fauna of South Africa. Whichever species turns up on a fence post or porch wall next, a closer look at its scales, tail, and toes is usually all it takes to put a name to it.
