GBIFID: 2563512689; Occurrence Remarks: Pine Nut Mountains. 2 individuals were seen this day, about 10 meters apart, and this is the smaller, younger one. Will post the larger, older Desert Horned Lizard as a separate observation later. Special note, they were located on an illegal dirt road in a drainage, that at the time had infrequent motorcycle and ATV traffic on it.. I ran into the president of the Pine Nut Trails Association (off-road organization) and one of his members here in 2018 and they agreed to notify their members to avoid this area. 2019 saw a continuation of the growing trend of off-roaders here, especially side-by-sides and four-seaters, a tenfold increase since 2017. These recreationists now pass through here in packs of 5 - 20 or more at high speeds with no concern for the native wildlife. I have been coming here since 1986, and things have changed... as far as reptiles go, they are disappearing from this area at an alarming rate. And before legislation was passed last year, reptile collectors were unregulated in their endeavors... that part of story has changed for the benefit of Nevadas reptiles.;; Coordinate Uncertainty in Meters: 4.00000.

Conservation Status: Vulnerable (S3S4) in California, US (NatureServe). Their range has been severely fragmented due to urbanization and habitat loss. Blainvilles Horned Lizard has a DOUBLE row of Side Scales on the flanks; Desert Horned Lizard (Phrynosoma platyrhinos) has a SINGLE row of side scales. Description: Juvenile has black spots on belley. Adults are 2.5 - 4.5 inches long from snout to vent (6.3 - 11.4 cm). It is a flat-bodied lizard with a wide oval-shaped body, scattered enlarged pointed scales on the upper body and tail, and a large crown of horns or spines on the head. The two center horns are the longest. Males have enlarged postanal scales and a swollen tail base during the breeding season. Each side of the body has two rows of pointed fringe scales. Each side of the throat has two or three rows of enlarged pointed scales. Females are larger in size than males. Color and Pattern: Color is reddish-brown, yellow, or gray, with dark blotches on the back and large dark spots on the sides of the neck. The belly is cream, beige, or yellow, usually with dark spots, and the belly scales are smooth. Activity: Diurnal. Active during periods of warm weather, retreating underground and becoming inactive during extended periods of low temperatures or extreme heat. Diet and Feeding: Eats mainly ants, especially harvester ants, but also consumes other small invertebrates such as spiders, beetles, termites, flies, honeybees, moth larvae, and grasshoppers.

Coast Horned Lizard: 2 rows of pointed fringe scales on flanks COMPARE My favorite Desert Horned Lizard (Phrynosoma platyrhinos) observations: Desert Horned Lizard (Phrynosoma platyrhinos) is a flat-bodied, well-camouflaged reptile in the Horned Lizards (Genus Phrynosoma) and Phrynosomatid Lizards (Phrynosomatidae) family that is found in arid habitats throughout the Colorado and Mojave deserts. The subspecies found in Southern California is the Southern Desert Horned Lizard (Phrynosoma platyrhinos calidiarum). Blainvilles Horned Lizard has a DOUBLE row of Side Scales on the flanks; Desert Horned Lizard (Phrynosoma platyrhinos) has a SINGLE row of side scales.

Lee Grismer and Marta S. Grismer, 2024. pp. 42-43 Desert Horned Lizard (Phrynosoma platyrhinos) is a mediumΓÇæsized, flatΓÇæbodied lizard of the Mojave and Colorado Deserts, easily recognized by its wide oval shape, blunt snout, and the short but sharp horns that project from the back of the head, with the two central horns being the longest. Its upper body is covered with small granular scales mixed with scattered pointed ones, and each side of the body carries a single row of wellΓÇædeveloped fringe scales, with a similar but smaller row along each side of the throat. Adults measure about 2.5 to 3.75 inches from snout to vent and show a range of colorsΓÇöreddish, tan, gray, beige, brown, or nearly black in lavaΓÇærock areasΓÇöusually matching the local soil. A pair of large dark blotches marks the neck, and the back shows wavy dark blotches that help break up the body outline. The underside is pale and smooth, with small black spots near the vent. Males are generally smaller than females and can be identified by postanal scales, femoral pores, and a slightly wider tail base, while juveniles show a more strongly contrasted pattern that softens with age. These lizards are active during the day and are well adapted to hot, open habitats, often basking on bare ground before moving to feed or burying themselves shallowly in loose soil. Their range in California includes most of the Mojave and Colorado Deserts, extending east to the Colorado River, south toward the Baja California border, and north through the Owens Valley to near Nevada, making them one of the characteristic reptiles of the stateΓÇÖs low desert landscapes.

For example: Blainvilles Horned Lizard (Phrynosoma blainvillii), a.k.a. Coast Horned Lizard: 2 rows of pointed fringe scales on flanks COMPARE My favorite Blainvilles Horned Lizard (Phrynosoma blainvillii) observations: Juvenile Spotted Belly: https://www.inaturalist.org/observations/128403054 Closeup: https://www.inaturalist.org/observations/49844521 Closeup of Sweet Face by Gary Nafis: Blainvilles Horned Lizard (Phrynosoma blainvillii), a.k.a. Coast Horned Lizard is a flat-bodied, well-camouflaged reptile in the Horned Lizards (Genus Phrynosoma) and Phrynosomatid Lizards (Phrynosomatidae) family that is native to Central and Southern California and northern Baja California, Mexico. Conservation Status: Vulnerable (S3S4) in California, US (NatureServe). Blainvilles Horned Lizard (Phrynosoma blainvillii), a.k.a. Coast Horned Lizard range has become heavily fragmented by development and habitat loss and is considered vulnerable in the state. Adults are about 2.5 to 4.5 inches from snout to vent and have a wide oval body with scattered pointed scales on the upper surface, a large crown of head horns with the two central horns longest, a blunt snout, and a distinctive double row of pointed fringe scales along each side of the body, a key feature that separates it from the desert horned lizard, which has only a single row. Each side of the throat carries two or three rows of enlarged pointed scales, and females grow larger than males, while males show enlarged postanal scales and a swollen tail base during the breeding season. Juveniles are easy to recognize by the dark spots on the belly, a pattern that fades with age. Their coloration ranges from reddishΓÇæbrown to yellow or gray, usually matching the local soil, with dark blotches on the back and large dark spots on the sides of the neck, and the belly is cream, beige, or yellow with smooth scales and dark spotting. These lizards are active during the day in warm weather and retreat underground during long periods of cold or extreme heat. They rely heavily on camouflage and short bursts of movement to avoid predators and feed mainly on ants, especially harvester ants, but also take spiders, beetles, termites, flies, honeybees, moth larvae, and grasshoppers.

Occurrence Remarks: Desert Horned Lizard (Phrynosoma platyrhinos), about 4 inches long, ran across the trail and was photographed through branches of a Creosote Bush. Huge boulders is all that remains of the historic old mining settlement called Pine City in Joshua Tree National Park in the Mojave Desert. My favorite Desert Horned Lizard (Phrynosoma platyrhinos) observations/photos: 1 row of fringe scales on flanks: Desert Horned Lizard (Phrynosoma platyrhinos) is a flat-bodied, well-camouflaged, diurnal, arid desert-adapted reptile in the Horned Lizards (Phrynosoma) genus and the Phrynosomatid Lizards (Phrynosomatidae) family. There are 2 subspecies: Northern and Southern Desert Horned Lizard. The subspecies found in Southern California Colorado and Mojave deserts is the Southern Desert Horned Lizard (Phrynosoma platyrhinos calidiarum). Desert Horned Lizard (Phrynosoma platyrhinos) has a SINGLE row of side scales on flanks; (Blainvilles Horned Lizard (Phrynosoma blainvillii), a.k.a. Coast Horned Lizard, has 2 rows of pointed fringe scales on flanks. Desert Horned Lizard (Phrynosoma platyrhinos) is a mediumΓÇæsized, flatΓÇæbodied lizard of the Mojave and Colorado Deserts, easily recognized by its wide oval shape, blunt snout, and the short but sharp horns that project from the back of the head, with the two central horns being the longest. Its upper body is covered with small granular scales mixed with scattered pointed ones, and each side of the body carries a single row of wellΓÇædeveloped fringe scales, with a similar but smaller row along each side of the throat. Adults measure about 2.5 to 3.75 inches from snout to vent and show a range of colorsΓÇöreddish, tan, gray, beige, brown, or nearly black in lavaΓÇærock areasΓÇöusually matching the local soil. A pair of large dark blotches marks the neck, and the back shows wavy dark blotches that help break up the body outline. The underside is pale and smooth, with small black spots near the vent. Males are generally smaller than females and can be identified by postanal scales, femoral pores, and a slightly wider tail base, while juveniles show a more strongly contrasted pattern that softens with age. These lizards are active during the day and are well adapted to hot, open habitats, often basking on bare ground before moving to feed or burying themselves shallowly in loose soil. Their range in California includes most of the Mojave and Colorado Deserts, extending east to the Colorado River, south toward the Baja California border, and north through the Owens Valley to near Nevada, making them one of the characteristic reptiles of the stateΓÇÖs low desert landscapes.

Lee Grismer and Marta S. Grismer, 2024, pp. 42-43 Irenes Horned Lizards (Phrynosoma) genus observations: Horned Lizard (Phrynosoma) Umbrella Project: an INaturalist Project: Horned lizards of the Mojave Desert are some of the most distinctive reptiles in the region, shaped by a landscape of open flats, sandy washes, and scattered shrubs. The main species here is the Desert Horned Lizard, which has a wide, flattened body, a blunt snout, and a crown of short but sharp horns at the back of the head. Its colors match the local soil, ranging from pale tan to reddish or gray, which helps it disappear against sand and gravel. The body is covered with small rough scales mixed with larger pointed ones, and a single row of fringe scales runs along each side, giving the lizard a slightly jagged outline that breaks up its shape. These features make it hard for predators to spot, especially when it stays still or partially buries itself in loose soil. In the Mojave Desert, horned lizards spend their days warming up in the morning sun, then moving slowly as they search for ants, which make up most of their diet. Harvester ants are especially important, and the lizards often sit near ant trails and snap them up as they pass. When temperatures rise, they shift into shade, lift their bodies off the hot ground, or dig shallow pits to cool down. Their movements are usually slow and deliberate, but they can sprint in short bursts when threatened. If a predator gets too close, they rely on camouflage first, but they can also puff up their bodies to look larger or run in a short zigzag before freezing again. Compared with other Mojave lizards, horned lizards are more specialized for a sitΓÇæandΓÇæwait lifestyle. Species like zebraΓÇætailed lizards and sideΓÇæblotched lizards are fast runners that chase insects in open areas, while horned lizards stay lower to the ground, move less, and depend heavily on antΓÇæeating. Their flattened shape, head spines, and antΓÇæbased diet set them apart from most other desert reptiles. These adaptations allow them to survive in some of the hottest, driest parts of the Mojave, making them one of the regionΓÇÖs most recognizable and wellΓÇæadapted lizard groups. Irenes Phrynosomatid Lizards (Phrynosomatidae) family observations on INaturalist, worldwide: Phrynosomatid Lizards (Phrynosomatidae) family: Phrynosomatid lizards are a large and familiar group in the desert Southwest, and they share a set of traits that help them thrive in hot, open, and often harsh environments. Most species are small to medium in size, with sturdy bodies, rough or spiny scales, and colors that match the soil or rocks where they live. This camouflage is one of their most important features, allowing them to blend into sand, gravel, or desert pavement so predators overlook them. Many species, like horned lizards, have flattened bodies and head spines, while others, like sideΓÇæblotched and earless lizards, have smoother bodies but still show the same earthy tones and quick, darting movements. They are mainly active during the day, warming up in the morning sun before hunting insects or defending territories. Because desert temperatures can rise quickly, they rely on behavioral tricksΓÇösuch as shifting into shade, lifting their bodies off hot ground, or retreating into burrowsΓÇöto avoid overheating. Compared with other lizard families, phrynosomatids tend to be more specialized for dry, open habitats. Many iguanids, skinks, and geckos live in forests, grasslands, or rocky tropical areas, but phrynosomatids dominate arid regions of the western United States. Their scales are usually rougher and more protective than those of smoothΓÇæskinned skinks, and their body shapes are often flatter and more angular than the sleeker forms seen in geckos or anoles. Horned lizards are especially distinctive because of their wide, pancakeΓÇælike bodies and crown of head spines, a look not found in other lizard families. Even the more typical species, like the sideΓÇæblotched lizard, differ from many other lizards by relying heavily on rapid colorΓÇæmatching camouflage and quick bursts of movement rather than climbing or longΓÇædistance running. In the desert Southwest, these traits allow phrynosomatids to fill many ecological roles, from antΓÇæeating specialists to fastΓÇæmoving insect hunters, making them one of the most characteristic reptile groups of the region.
