11 Types of Lizards in Florida: A Backyard Guide to Native and Invasive Species
September 20, 2026
Step onto almost any patio in the Sunshine State and something small, scaly, and quick will probably dart past your foot within minutes. Florida has more established nonnative lizard species than anywhere else on the planet, and identifying the different types of lizards in Florida has become a genuine hobby for homeowners, hikers, and weekend naturalists alike. Some of these reptiles have lived here for thousands of years; others arrived in shipping crates a few decades ago and never left.
This guide walks through 11 lizards you’re likely to encounter across the state, from the sand-loving Florida scrub lizard to the imposing red tegu now turning up along South Florida roadsides. Knowing which species is native, which is invasive, and which is harmless but startling can change how you react the next time one scurries across your driveway.
1. Florida Scrub Lizard
The Florida scrub lizard (Sceloporus woodi) is one of the state’s true habitat specialists. Florida scrub lizards are habitat specialists that require open scrub with large areas of bare sand, but also trees and shrubs to provide shade during the heat of the day. They tend to stick to inland ridges of central Florida rather than beaches, and they grow to about 7 inches and feed on small insects.
Spotting one takes a sharp eye. Adults reach up to 7 inches long, with four light stripes running the length of the body and a portion of the tail, though juveniles are sometimes all black with no markings, and during the breeding season some males develop reddish blotches on the sides of the head. The easiest tell is on the underside: one of the easiest ways to spot the Florida Scrub Lizard is to look toward its belly, which has two brilliant turquoise spots, and the color is truly striking.
Pro Tip: Because scrub lizards depend on open sandy patches with scattered shade, they’re most active on warm, sunny mornings. Look for them near pine flatwoods or scrub oak, not in shaded yards or dense forest.
2. Skinks
Florida hosts several skink species, and they’re often mistaken for each other or for young anoles because of their smooth, shiny scales. The coal skink (Plestiodon anthracinus) is one of the more secretive members of the group. The Coal Skink is a secretive lizard that prefers to live in rural areas away from development.
Identification comes down to stripe patterns. They are brown or black and have four light stripes with two thicker dark stripes in between each pair, and any skink that is nearly black is a type of coal skink, while coal skinks have blunter heads than the five-lined skink and no stripe along the spine. Range and habitat details help narrow things down further: coal skinks stick to northwestern Florida, are commonly found in leaf litter in forests, measure 5 to 8 inches, and range in color from beige to black with a dark side stripe as the key identification mark.
Florida’s other common skinks — the five-lined, southeastern five-lined, and broad-headed skink — share the same general body plan but differ in size and stripe boldness. Readers researching lizard species Alabama-wide will recognize several of these skinks, since the same genus ranges across much of the Gulf Coast into neighboring states.
| Skink Type | Typical Size | Key ID Feature | Habitat |
|---|---|---|---|
| Coal Skink | 5–8 inches | Dark side stripe, no spine stripe | Leaf litter, moist forests |
| Five-Lined Skink | 5–8.5 inches | Blue-tinted tail (juveniles) | Woodlands, leaf piles |
| Broad-Headed Skink | 6.5–12.75 inches | Wide, orange-tinted head | Tree trunks, wooded yards |
3. Glass Lizards
Few Florida reptiles cause more confusion than glass lizards, which have no legs and are frequently mistaken for snakes. Florida is home to two groups of legless lizards that are often mistaken for snakes — the glass lizards and wormlizards. There are four species of glass lizards found in Florida, all belonging to the genus Ophisaurus, ranging in size from 15 to 40 inches long and usually tan, brown, or greenish, often with dark lengthwise stripes on their backs.
The giveaway that separates them from true snakes is anatomical, not just visual. Glass lizards are legless, and their long tails give them a very snake-like appearance, but unlike snakes, they have moveable eyelids and external ear openings. Their defense mechanism is dramatic: glass lizards have very smooth, shiny scales reinforced by bones called osteoderms, making the lizards’ bodies hard and brittle, so their tails break easily and they are often seen with broken tails in the process of regrowth.
The University of Florida’s wildlife extension program notes that these lizards prefer loose, sandy soil and spend much of their time burrowed underground, which is part of why they’re rarely seen despite being fairly common. Anyone comparing legless lizard species found in other tropical regions will notice similar burrowing adaptations show up worldwide, even among unrelated lizard families.
4. Green Anole
The green anole (Anolis carolinensis) is Florida’s only native anole and one of the few lizards on this list that predates European settlement. It’s slender, typically bright green (though it can shift toward brown depending on temperature and mood), and displays a pink throat fan called a dewlap during territorial disputes.
Green anoles play a genuinely useful role in yards and gardens. Green anoles are beneficial native species that eat pest insects and contribute to a healthy yard ecosystem. Carolina anoles are beneficial insect predators, and removing them disrupts a yard’s natural pest control.
Unfortunately, competition from an invasive cousin has pushed green anoles higher into the tree canopy across much of the state — a shift covered in more detail in the next section. Homeowners hoping to encourage native lizards, including those researching Alabama lizard identification for their own backyards, can help green anoles by reducing pesticide use and preserving shrubby cover near the ground.
5. Brown Anole
If there’s one lizard almost every Florida resident has seen, it’s the brown anole (Anolis sagrei). The Brown Anole was introduced to south Florida from the West Indies in the 1880s, and it has since become the state’s most numerous reptile by a wide margin.
Its population numbers are hard to overstate. Brown anoles are Miami’s most abundant non-native lizard, accounting for an estimated 44 percent of all reptiles and amphibians in Miami-Dade County in one recent university survey. The brown anole is the most widespread invasive lizard, and it has spread across Florida so thoroughly that many people think it’s native.
The competitive edge brown anoles hold over native green anoles comes down to where each species prefers to perch. Unlike green anoles, brown anoles tend to stay closer to the ground, effectively taking over backyards and pushing green anoles up into the trees.
Distinguishing the two is straightforward once you know the traits: brown anoles show tan, gray, and brown tones with a cream-colored belly that fades into brown on the sides, along with dark stripes running down the back that can be hard to spot.
6. House Geckos
Anyone who has flipped on a porch light in Florida after dark has probably met a house gecko. These small, nocturnal climbers are common throughout the state’s urban and suburban areas. This gecko is small and slender, measuring about 7 to 10 centimeters in total length, including the tail, with skin covered in small, granular scales and a pattern of pale gray or tan coloration, often marked with darker spots or bands.
Their climbing ability is the real party trick. The toes have expanded pads with tiny hairs that allow the gecko to climb smooth surfaces, and in Florida this species is often seen on the exterior walls and windows of buildings, especially in urban and suburban areas where artificial light attracts insects. The house gecko has adapted perfectly to urban life, and stepping outside on a warm night in southern Florida, you’ll likely see one clinging to a wall, waiting to snap up insects drawn to porch lights.
House geckos aren’t unique to Florida — similar species have colonized warm coastal regions of Hawaii and tropical parts of the Philippines through the same shipping and pet-trade routes. For a closer look at Florida’s broader gecko lineup, including the far louder tokay gecko, see this guide to Florida’s gecko species.
Pro Tip: If you hear a loud, repeated “to-kay” call at night, you’re likely not hearing a house gecko. That sound belongs to the much larger, invasive tokay gecko, which can bite if handled.
7. Green Iguana
The green iguana (Iguana iguana) is the lizard most responsible for Florida’s reputation as an exotic-reptile hotspot. Green iguanas are the most widely established large nonnative lizards in Florida, and they’ve become a common — if unwelcome — sight along canals, seawalls, and landscaped neighborhoods in the southern half of the state.
Size alone makes them hard to miss. Green iguanas have a subtympanic shield, a large round scale on each side of the head below the ear that’s unique to the species, and mature adults weigh between 10 and 20 pounds. They’re frequently confused with the state’s other large lizards, though Carolina anoles, knight anoles, and Cuban knight anoles are frequently mistaken for young iguanas due to their vivid green appearance, even though accurate identification matters because green iguanas cause significant property damage while the smaller green lizards are mostly harmless.
Because iguanas burrow into seawalls and levees, wildlife officials treat them as a genuine infrastructure concern rather than just a nuisance. Invasive lizards, especially iguanas, may require active management, and understanding the various types of iguanas in Florida can help homeowners identify which species they’re dealing with and choose the most effective approach. Anyone curious about how green iguanas compare to lizards kept legally as pets can find useful context in this overview of popular pet reptile species.
8. Peter’s Rock Agama (Rainbow Lizard)
Few Florida lizards turn heads quite like the Peter’s Rock Agama (Agama picticauda), better known locally as the rainbow lizard. The rainbow lizard is actually the Peter’s Rock Agama, originally from West Africa, and its arrival in South Florida has been recent enough that many longtime residents still find it startling.
Its coloring alone explains the nickname. Adult males in breeding coloration have a bright orange or red head, black body, and an orange and black tipped tail, subordinate males are duller with a greyish back, and females are a drab brownish gray with light green spots and stripes on the head and neck area.
The species belongs to a much larger reptile family: the family Agamidae has roughly 500 known species native to Africa, Asia, Australia, and Europe, and there are four species of Agamid lizards with established populations in Florida, with Peter’s Rock Agama the most widespread, growing to 12 inches in males and slightly smaller in females.
Population growth has been fast by any standard. Rainbow lizards and curly-tailed lizards have seen unprecedented rates of growth in South Florida, according to Christopher Searcy, an associate professor of biology at the University of Miami College of Arts and Sciences, whose lab studies the changing community of nonnative reptiles in Miami.

9. Curly-Tailed Lizard
The curly-tailed lizard gets its name from an obvious habit: it curls its tail into a tight spiral, especially when startled or displaying to a rival. Residents across South Florida’s tri-county area are seeing more of this bold-personality species, including the curly-tailed lizards running around and dashing across roads.
These lizards are ground-dwellers through and through, which sets them apart from anoles and geckos that spend most of their time climbing. Ground-active lizards that sprint across open areas are more likely skinks, racerunners, or curly-tailed lizards rather than the vertical-surface specialists like anoles and geckos. Their thick, spiny-scaled bodies and stocky build make them fairly easy to tell apart from Florida’s slimmer native reptiles once you know what to look for.
Like the rainbow lizard, curly-tailed lizards have expanded rapidly through South Florida’s warm, developed neighborhoods, often turning up on sidewalks, parking lots, and rock walls. Interested readers researching Alabama wildlife guide topics may notice this species hasn’t established populations that far north yet, since curly-tailed lizards remain concentrated in Florida’s warmest coastal counties.
10. Red Tegu
Of everything on this list, the red tegu (Salvator rufescens) represents the newest and most closely watched arrival. Red tegus have been found in south Florida, but with no evidence of breeding, and they spend most of their time on land, often observed on roadsides or disturbed areas, according to a fact sheet from the Everglades Cooperative Invasive Species Management Area.
Wildlife managers pay close attention to tegus specifically because of what they eat. Tegus are diet generalists and opportunistic feeders that consume native fruits, insects, small reptiles, and occasionally small mammals and birds, and they have an affinity for eggs, making them a threat to ground-nesting birds and reptiles including threatened and endangered species such as sea turtles and burrowing owls.
Context matters here: red tegus are one of several large lizard species that arrived through the exotic pet trade. Species of nonnative reptiles breeding in Florida currently outnumber native species, illustrated by the fact that the four largest lizards breeding in Florida are from Africa, South America, Central America, and Mexico. The University of Florida’s quick reference guide to large lizards is a useful tool for anyone trying to tell tegus, monitors, and iguanas apart in the field.
Pro Tip: If you spot a red tegu or Argentine black-and-white tegu in the wild, Florida wildlife officials ask that sightings be reported rather than handled, since both species are part of active removal efforts in South Florida.
11. Eastern Fence Lizard
The eastern fence lizard (Sceloporus undulatus) rounds out this list as one of Florida’s most familiar native reptiles, especially outside the peninsula’s southern tip. This species ranks among the most common lizards in the state, alongside the brown anole and green anole, and it’s a frequent sight on tree bark, fence posts, and woodpiles.
Habitat preference sets this species apart from the sand-loving scrub lizard covered earlier. In Florida’s wetlands and marshes, species like the eastern fence lizard and the five-lined skink are excellent swimmers and can often be seen basking on logs or rocks near the water. Its rough, gray-brown, keeled scales provide natural camouflage against tree bark, and males display blue patches on the throat and belly during breeding season.
Because its range stretches well beyond Florida into Texas and even portions of Arizona, the eastern fence lizard is one of the few species on this list that a visitor could recognize from several states away. It’s also common enough in Alabama and across the broader Southeast that most native Alabama reptiles lists include it as a baseline species for lizard identification.
Telling Native Species from Invasive Arrivals
Florida’s lizard population tells a bigger story about the state’s ecology. Florida has experienced more introductions of nonnative reptile species than any other region on Earth, and there are approximately three times as many established nonnative lizard species in the state as native ones, ranging in size from the small Cuban brown anole to the large Nile monitor, with roughly 50 nonnative lizard species established overall.
That imbalance matters for anyone trying to identify what’s sunning itself on the back porch. Exotic lizards currently outnumber native lizards by roughly 3 to 1, with no natural predators allowing them to rapidly reproduce and quickly overwhelm native species, sometimes by preying on them directly or competing for food and habitat. The good news is that most of the truly native species — green anoles, fence lizards, scrub lizards, and the various skinks — are harmless and genuinely beneficial to have around.
For a broader look at how Florida’s reptile diversity compares to other regions, this guide to lizard species found in Tennessee shows how far fewer nonnative species have established themselves outside the subtropics. The contrast highlights just how unusual Florida’s situation is among U.S. states.
Frequently Asked Questions
Readers new to Florida’s reptile scene tend to ask the same handful of questions. Are any of these lizards dangerous? None of the 11 species covered here pose a serious threat to people — tegus and iguanas can bite if cornered or handled, but they aren’t aggressive toward humans under normal circumstances.
What should you do if you find one in your house? Most indoor sightings involve house geckos or anoles that wandered in through an open door; they’re harmless and will typically find their way back outside on their own or can be gently guided out with a cup and piece of paper.
Should invasive species be reported? Florida Fish and Wildlife Conservation Commission asks residents to report sightings of large invasive species like tegus, green iguanas, and Nile monitors, since early detection helps limit their spread into new counties.
The sheer variety covered in this rundown of the types of lizards in Florida barely scratches the surface of the state’s full reptile diversity, but it covers the species most people will actually encounter. Whether it’s a green anole doing push-ups on a fence post or a rainbow-colored agama sunning on a rock wall, each of these lizards has a story tied to Florida’s unusual mix of native wildlife and decades of accidental introductions.
