California’s deserts, forests, grasslands, mountains, coastal scrub, and neighborhoods support an impressive variety of lizards. This guide to the types of lizards in California covers 36 native species and regional forms, including horned lizards, alligator lizards, fence lizards, whiptails, skinks, geckos, and the unusual legless lizards. Learn how to recognize them by appearance, habitat, behavior, size, and geographic range.
What Are the Main Types of Lizards in California?
The main types of lizards in California include fence lizards, alligator lizards, horned lizards, leopard lizards, whiptails, collared lizards, skinks, geckos, night lizards, and legless lizards. Some are widespread, while others occur only in specialized desert, mountain, coastal, or valley habitats. Most California lizards eat insects and other small invertebrates, although a few also consume plants, small vertebrates, or eggs.
1. Western Fence Lizard
Scientific name: Sceloporus occidentalis. The Western Fence Lizard is one of California’s most familiar reptiles. Adults commonly measure about 4 to 8 inches including the tail and have brown, gray, or olive backs with dark markings. Males often display a vivid blue patch on the throat and belly.
It lives in woodlands, chaparral, grasslands, rocky slopes, farms, parks, and suburban yards. Fence lizards bask on logs, rocks, fences, and walls, then quickly retreat when approached. Their diet consists mainly of ants, beetles, spiders, flies, and other small invertebrates.
2. San Joaquin Fence Lizard
Scientific name: Sceloporus occidentalis biseriatus. This regional form of the Western Fence Lizard occurs around the San Joaquin Valley and nearby foothills. It resembles other fence lizards but may show subtle differences in pattern, body proportions, and range.
Look for it on fence posts, fallen branches, rocky ground, and dry vegetation. It is an active insect hunter that often warms itself in open sunlight. Identification is most reliable when location is considered along with color and markings.
3. Coast Range Fence Lizard
Scientific name: Sceloporus occidentalis bocourtii. The Coast Range Fence Lizard is associated with coastal hills, oak woodland, chaparral, and valleys west of California’s interior ranges. Its brown or gray body usually blends well with bark, stones, and dry leaves.
Males may show blue coloring on the throat and abdomen. These lizards bask during the day and feed on insects and spiders. They are common in sunny clearings and along trails where rocks and branches provide both warmth and escape cover.
4. Great Basin Fence Lizard
Scientific name: Sceloporus occidentalis longipes. This form is found in parts of northeastern California and the Great Basin region. It occupies open woodland, sagebrush, rocky hillsides, and high desert environments.
Its mottled gray-brown appearance provides camouflage among granite, soil, and sagebrush. Like other fence lizards, it spends much of the day basking and searching for insects. Seasonal activity is strongly influenced by temperature and elevation.
5. Desert Spiny Lizard
Scientific name: Sceloporus magister. The Desert Spiny Lizard has strongly keeled, rough-looking scales and a sturdy body. It is usually gray, tan, or brown, with dark bars or patches that help it disappear against desert rocks.
It lives in the Mojave and Colorado deserts, rocky washes, canyon walls, and desert foothills. This fast, alert lizard feeds on insects, spiders, and occasionally plant material. It often perches on shrubs or rocks to survey its surroundings.
6. Great Basin Collared Lizard
Scientific name: Crotaphytus bicinctores. The Great Basin Collared Lizard is a large-headed desert lizard with two dark bands around the neck. It occurs east of the Sierra Nevada and in parts of northeastern and southeastern California.
Adults may reach roughly 10 to 14 inches including the tail. They eat insects, spiders, and sometimes smaller lizards. When startled, they can run rapidly on their hind legs, a behavior that makes them especially interesting to observe in open desert terrain.
7. Baja California Collared Lizard
Scientific name: Crotaphytus vestigium. This colorful collared lizard occurs in southern California’s desert regions, especially rocky areas near the Mexican border. It has a broad head, strong jaws, long tail, and dark neck bands.
Color varies by location and sex, with males often showing brighter blue, green, orange, or yellow tones. It hunts insects and other small animals from exposed rocks. Warm, open habitats with scattered boulders are excellent places to look for it.
8. Mojave Collared Lizard
Scientific name: Crotaphytus bicinctores in many California references. This desert collared lizard is recognized by its large head, neck bands, long limbs, and powerful sprinting ability.
It favors rocky desert slopes, canyon edges, and open flats with nearby cover. Its prey includes beetles, grasshoppers, spiders, and smaller reptiles. Because similar collared lizards overlap in appearance, exact location is important for identification.
9. Coast Horned Lizard
Scientific name: Phrynosoma blainvillii. The Coast Horned Lizard has a flattened body, pointed scales, and horn-like projections on its head. Its brown, gray, or reddish pattern closely matches soil, gravel, and leaf litter.
It occurs in coastal plains, valleys, foothills, chaparral, and open woodland. Ants make up much of its diet, especially native harvester ants. Habitat loss, invasive ants, roads, and disturbance can affect local populations.
10. Desert Horned Lizard
Scientific name: Phrynosoma platyrhinos. The Desert Horned Lizard is adapted to sandy and rocky deserts. It has a broad flattened body, short legs, a spiny back, and two prominent horns toward the rear of its head.
Its camouflage makes it difficult to spot as it sits motionless on desert ground. It mainly eats ants but may take other small insects. Never collect or handle wild horned lizards; observing them quietly is safer and less stressful.
11. Blunt-Nosed Leopard Lizard
Scientific name: Gambelia sila. The Blunt-Nosed Leopard Lizard is a threatened species of California’s San Joaquin Valley and nearby dry regions. It has a broad, blunt snout, long tail, and spotted or barred pattern.
It lives in open grassland, scrub, and alkaline valley habitats. This active predator eats insects, spiders, small lizards, and occasionally plant material. Agricultural conversion and habitat fragmentation have greatly reduced suitable habitat.
12. Long-Nosed Leopard Lizard
Scientific name: Gambelia wislizenii. The Long-Nosed Leopard Lizard has a pointed snout, long legs, and dark spots that resemble leopard markings. It occurs in deserts, shrublands, grasslands, and open valleys across much of inland California.
It hunts by sight and may eat insects, small mammals, young birds, and other lizards. Adults can become surprisingly large, sometimes exceeding a foot in total length. Open ground and scattered shrubs are typical habitat features.
13. Baja California Leopard Lizard
Scientific name: Gambelia copeii. This leopard lizard is associated with southern California and the Baja California region. Its body is usually tan or gray with bold spots, bars, or pale markings.
It favors dry open habitats where it can run quickly after prey. Its diet includes insects and smaller reptiles. Identification should include snout shape, pattern, habitat, and geographic location because several leopard lizards look similar.
14. Southern Alligator Lizard
Scientific name: Elgaria multicarinata. The Southern Alligator Lizard has overlapping keeled scales, a long body, short legs, and a tapering tail. Brown, gray, and olive patterns give it an alligator-like appearance.
It occurs in woodland, chaparral, gardens, coastal hills, and mountain foothills. It eats insects, spiders, slugs, small mammals, eggs, and other lizards. When threatened, it may bite, thrash, or release its tail, so wild individuals should be left alone.
15. San Diego Alligator Lizard
Scientific name: Elgaria multicarinata webbii. This southern form of the Southern Alligator Lizard is found in parts of coastal Southern California and nearby inland areas. It has a long, muscular body and strongly textured scales.
Look for it beneath logs, rocks, dense vegetation, and garden debris. It is most active during mild weather and feeds on a broad range of small prey. Its dark crossbands and narrow head can help distinguish it from other local lizards.
16. Sierra Alligator Lizard
Scientific name: Elgaria coerulea palmeri. The Sierra Alligator Lizard is associated with cooler forests and mountain habitats. Its coloring may range from brown and gray to greenish tones, with juveniles sometimes showing brighter colors.
It prefers moist ground, fallen logs, rock piles, and forest edges. The species eats insects, worms, spiders, and other small animals. Higher elevations and shaded habitat are useful clues when identifying it.
17. Forest Alligator Lizard
Scientific name: Elgaria multicarinata multicarinata. The Forest Alligator Lizard occurs in northern California, the Central Valley margins, and nearby woodland habitats. It has a long tail, rough scales, and dark bands across the back.
It may climb, swim, or move through leaf litter when escaping danger. Forest edges, fallen timber, and shaded gardens provide suitable cover. Its diet includes insects, slugs, small reptiles, and other available prey.
18. Panamint Alligator Lizard
Scientific name: Elgaria panamintina. The Panamint Alligator Lizard is a localized species of the desert mountain ranges of eastern California. It is generally brown or gray with a long body and a banded tail.
Unlike many desert lizards, it often uses cooler, elevated habitats such as rocky springs, canyon vegetation, and mountain woodland. Its restricted range makes geography especially important for identification.
19. Northern Alligator Lizard
Scientific name: Elgaria coerulea. Northern Alligator Lizards inhabit cooler northern forests, mountain slopes, and moist woodland edges. Their rough scales, long bodies, and dark crossbands are characteristic.
They feed on insects, spiders, worms, and other small prey. These lizards often shelter under logs or stones and are less likely to be seen in hot, exposed desert landscapes.
20. Western Skink
Scientific name: Plestiodon skiltonianus. The Western Skink is a smooth-scaled lizard with a slender body and a bright blue tail, especially in young individuals. Adults may become brown or gray as the blue fades.
It occurs in woodland, grassland, rocky areas, and moist edges across much of California. It eats insects, spiders, and other small invertebrates. The blue tail is an excellent field clue, but color alone should not be used for exact identification.
21. Gilbert’s Skink
Scientific name: Plestiodon gilberti. Gilbert’s Skink is a smooth, shiny lizard that may have reddish, orange, or brown coloring along the head and body. It is found in parts of central and southern California.
It prefers areas with leaf litter, downed wood, rocks, and moderate moisture. Its diet consists mainly of insects and spiders. A quick glimpse may reveal only its glossy scales and fast-moving body.
22. Western Whiptail
Scientific name: Aspidoscelis tigris. The Western Whiptail has a slender body, long tail, and striped or spotted pattern. Its coloring ranges from gray and brown to yellowish, helping it blend into desert scrub and open woodland.
It is a fast-moving daytime hunter that eats insects, spiders, scorpions, termites, and sometimes smaller lizards. Sandy washes, rocky slopes, and dry scrub are common habitats.
23. Orange-Throated Whiptail
Scientific name: Aspidoscelis hyperythra. The Orange-Throated Whiptail is a small striped lizard of coastal Southern California and nearby Baja California. Males often develop a vivid orange throat and belly during the breeding season.
It prefers coastal sage scrub, chaparral, open woodland, and disturbed but vegetated areas. This active lizard searches through leaf litter and soil for ants, beetles, termites, and other small prey.
24. Baja California Whiptail
Scientific name: Aspidoscelis labialis. The Baja California Whiptail reaches the southern edge of California in limited areas. It has the long tail and quick movements typical of whiptails, with narrow stripes and muted brown or gray coloring.
It lives in dry scrub, rocky terrain, and open ground. Identification can be difficult where whiptail ranges meet, so distribution and detailed pattern are both important.
25. California Whiptail
Scientific name: Aspidoscelis marmorata. The California Whiptail is a slender, active lizard with fine striping and a long tail. It occurs in parts of southern and southeastern California, especially dry open habitats.
It spends much of the day searching for insects and other small invertebrates. Its speed, narrow body, and constantly moving tail distinguish it from heavier-bodied fence and alligator lizards.
26. Common Side-Blotched Lizard
Scientific name: Uta stansburiana. The Common Side-Blotched Lizard is small, widespread, and highly variable in color. A dark spot behind the foreleg is a useful clue, while males may show blue or orange throat and belly colors.
It lives in deserts, grasslands, chaparral, woodland edges, parks, and yards. It eats insects and spiders and often basks on small rocks or bare soil. Its abundance makes it one of California’s easiest lizards to encounter.
27. Sagebrush Lizard
Scientific name: Sceloporus graciosus. The Sagebrush Lizard is a small, rough-scaled species found in sagebrush, pine woodland, mountain meadows, and dry slopes. It usually has a gray or brown body with subtle dark markings.
Males may show blue coloring on the belly and throat. It hunts small insects from the ground, rocks, and low vegetation. Elevation, sagebrush habitat, and its smaller size help separate it from larger fence lizards.
28. Western Sagebrush Lizard
Scientific name: Sceloporus graciosus gracilis. This regional form occurs across portions of California’s inland valleys, foothills, and mountain landscapes. It has a delicate build and muted pattern that blends into dry vegetation.
It is active in daylight and feeds on ants, beetles, flies, and other small arthropods. Look for it on sunny rocks, fallen wood, and open ground near shrubs.
29. Common Chuckwalla
Scientific name: Sauromalus ater. The Common Chuckwalla is a large, heavy-bodied desert lizard with loose skin and a thick tail. Adults may exceed 15 inches in total length, and their gray, brown, or reddish colors vary by location and sex.
It lives among boulder piles in the Mojave and Colorado deserts. Chuckwallas eat leaves, flowers, and other plant material. When threatened, they wedge themselves into cracks and inflate their bodies so predators have difficulty pulling them out.
30. Desert Iguana
Scientific name: Dipsosaurus dorsalis. The Desert Iguana is a pale, heat-tolerant lizard with a rounded body, long tail, and a row of enlarged scales along its back. It is common in hot desert valleys and sandy washes.
Unlike many California lizards, it eats a significant amount of plant material, including leaves, flowers, and fruit. It often shelters beneath creosote bushes, which provide shade and food.
31. Common Leopard Gecko
Scientific name: Gambelia wislizenii is sometimes confused with leopard geckos in casual descriptions, but California’s native leopard lizards are different from the common pet leopard gecko. True leopard geckos are not native California wildlife.
When identifying a wild California lizard, rely on habitat, body shape, and regional range rather than pet-trade names. Do not release captive geckos outdoors, where they may suffer or create ecological problems.
32. Western Banded Gecko
Scientific name: Coleonyx variegatus. The Western Banded Gecko is a small nocturnal lizard with soft-looking skin, large eyes, and dark bands across the tail and body. It occurs in desert regions of southeastern California.
Unlike daytime baskers, it becomes active after sunset and hunts insects and spiders. Rocky crevices, sandy washes, and debris provide daytime shelter. Its eyelids and slow, deliberate movements help distinguish it from many other desert lizards.
33. Great Basin Night Lizard
Scientific name: Xantusia vigilis. The Great Basin Night Lizard is a small, secretive lizard with a short tail and compact body. It often lives beneath fallen yucca leaves, logs, rocks, or dense desert vegetation.
It is generally crepuscular or nocturnal and eats small insects and spiders. Because it spends so much time hidden, it is less frequently observed than fence lizards or side-blotched lizards.
34. Southern Sagebrush Night Lizard
Scientific name: Xantusia henshawi. This localized night lizard occurs in rocky coastal and inland habitats of Southern California. It has a small body, subdued brown or gray pattern, and secretive habits.
It shelters beneath rocks and plant debris and feeds on tiny invertebrates. Its restricted range and concealed lifestyle make careful habitat-based identification important.
35. Southern California Legless Lizard
Scientific name: Anniella stebbinsi. The Southern California Legless Lizard looks more like a small snake than a lizard because it lacks visible legs. It has a cylindrical body, smooth scales, and a blunt tail that can resemble its head.
It lives underground in loose soil, sand, leaf litter, and coastal or inland habitats. It eats insects and other small invertebrates. Unlike snakes, it has movable eyelids and external ear openings, which are useful identification clues.
36. Northern California Legless Lizard
Scientific name: Anniella pulchra. The Northern California Legless Lizard is a slender burrowing species often associated with sandy soils, coastal dunes, and loose woodland ground. Its color may be silver, tan, brown, or dark depending on the form and location.
It spends much of its life beneath the surface, where it hunts small insects and larvae. Habitat disturbance, soil compaction, and loss of sandy ground can threaten local populations.
How Are These Lizards Classified?
California lizards belong to several families and evolutionary groups. Fence lizards, spiny lizards, and sagebrush lizards are generally placed in the Phrynosomatidae family. Alligator lizards belong to the Anguidae family, while skinks belong to the Scincidae family.
Whiptails are members of the Teiidae family, horned lizards belong to the Phrynosomatidae, and legless lizards are placed in the Anguidae family. Common names can be confusing, so scientific names and geographic range are useful when species look alike.
Where Do These Lizards Live?
- Deserts: Chuckwallas, desert iguanas, horned lizards, collared lizards, leopard lizards, geckos, and whiptails.
- Forests and mountains: Alligator lizards, fence lizards, sagebrush lizards, and skinks.
- Coastal scrub: Coast horned lizards, orange-throated whiptails, alligator lizards, and legless lizards.
- Valleys and grasslands: Side-blotched lizards, leopard lizards, fence lizards, and whiptails.
- Rocky habitats: Chuckwallas, collared lizards, spiny lizards, and night lizards.
- Underground or hidden habitats: Legless lizards and night lizards.
What Do California Lizards Eat?
Most California lizards are insectivores that eat ants, beetles, grasshoppers, termites, flies, spiders, and other arthropods. Larger predators such as leopard lizards and collared lizards may also eat small lizards, rodents, or young birds. Chuckwallas and desert iguanas eat mostly plants, including leaves, flowers, and fruit. Legless lizards consume small underground invertebrates.
How Do California Lizards Behave?
- Basking: Many species warm themselves on rocks, branches, pavement, or fence posts.
- Running: Whiptails and collared lizards are especially fast in open ground.
- Climbing: Fence lizards and alligator lizards commonly use logs, shrubs, trees, and walls.
- Burrowing: Legless lizards and some horned lizards spend substantial time below the surface.
- Tail defense: Some lizards can drop their tails when attacked.
- Camouflage: Desert species often match sand, gravel, rocks, or dry vegetation.
How to Identify Different Types of Lizards in California
- Start with the habitat: desert, coastal scrub, forest, grassland, mountain, or urban yard.
- Note the body shape: flattened, slender, heavy-bodied, long-tailed, or legless.
- Look for special markings such as blue belly patches, neck collars, horns, stripes, spots, or tail bands.
- Estimate size, but remember that age and tail loss can change appearance.
- Observe behavior, including basking, climbing, sprinting, burrowing, or nighttime activity.
- Use range and elevation to separate similar-looking species.
- Take photographs from a distance rather than catching the animal.
Outdoor Observation Tips
Search on mild sunny days when lizards are likely to bask. Move slowly, stop often, and scan rocks, logs, fence posts, shrubs, and trail edges. Early morning and late afternoon can be productive in hot deserts, while midday may be better in cooler mountain habitats.
Use binoculars or a camera with a zoom lens when possible. Never overturn rocks or logs without replacing them carefully, and avoid blocking a lizard’s escape route.
Are California Lizards Dangerous?
Most California lizards are harmless to people and prefer to flee. Alligator lizards can bite if handled, and the Gila monster, a venomous lizard found in limited areas of southeastern California, should never be approached or touched. Wash hands after handling reptiles, and keep pets away from wild animals.
