Reptiles

On This Page Navigation

 

Generally, reptiles are cold-blooded vertebrates that breath air through their lungs and have scales, including snakes, lizards, turtles, and alligators. Snakes and lizards are the only reptilian residents of Capitol Reef. As ectotherms (cold-blooded animals) reptiles rely on warmth from the environment and therefore become inactive during cold winter months. During this period of seasonal inactivity (brumation) snakes and lizards shelter in rock crevices or underground burrows and their metabolic rate decreases, conserving energy.

Snakes

Capitol Reef is home to 6 snake species. Snakes are mostly solitary animals and may be seen basking on a sunlit rock or unseen taking shelter in a dark rock crevice. Snakes are predators that swallow their food whole. They have extremely flexible jaws that allow them to swallow animals bigger than their heads, like chipmunks and squirrels.

Gopher Snake

Gopher snakes (Pituophis catenifer) are found throughout most of North America and are common throughout Utah, including in the park. When alarmed, gopher snakes hiss and vibrate their tails, thus they are often mistaken for rattlesnakes. Their diet consists of birds, bird eggs, small mammals, lizards, and insects. They are typically large, with individuals longer than 100 in (250 cm) in length not uncommon. Their backs are yellowish or cream colored with dark blotches, and their bellies are whitish or yellowish in color.

Lizards

Capitol Reef is home to 10 species of lizards which are frequently seen in the park on warm sunny days. Many lizard species engage in amusing territorial behaviors; they do push-ups! Males can be spotted doing short rapid push-ups to defend their territories and attract females. In some lizard species, breeding males have brightly colored throats and abdomen to attract mates. Most lizards also have the unique defensive adaptation of being able to drop and regrow their tails. Losing a tail is energetically costly, but may allow a lizard to escape the jaws of a predator or distract one that is too close for comfort.

Great Basin Collared Lizard

Great Basin collared lizards (Crotaphytus bicinctores) are found throughout the western US including western Utah and are common in the park. Like many other lizards, they are attracted to rocky hilly terrain with generally scant vegetation. These areas provide rock crevices for shelter, warm basking sites, and lookouts for prey. Their diet consists of lizards, insects, spiders, and some plant material.

Long-nosed Leopard Lizard

Leopard lizards (Gambelia wislizenii) are found throughout Utah in open desert and semi-desert areas and are common in the park. These lizards are mainly ground dwelling, but will occasionally climb into bushes. Their diet consists of insects, spiders, small rodents, lizards, and some plant material. These relatively large lizards can slightly alter their coloration for camouflage purposes. At top speeds they can run soley using their hind legs.

Western Whiptail Lizard

Western Whiptail

Western whiptails (Aspidoscelis tigris) are the more common of the two species of whiptails found in Capitol Reef and are present throughout much of the western U.S. They are slender, long-tailed lizards with little differentiation between head and body. They primarily inhabit sparsely vegetated desert and shrubland habitats. During cold winter months, they often occupy underground burrows created by rodents or other lizards. Whiptails feed primarily on insects, scorpions, lizards, and spiders.

Desert Spiny Lizard

Desert Spiny Lizard

Desert spiny lizards (Sceloporus magister) are stocky, have pronounced scales, and are of the spiny lizard family. They are native to southern and eastern Utah and common in the park. Their heads are yellowish orange while their bodies are flecked with gold or yellow. Desert spiny lizards have distinctive black marks on each side of their necks. They prefer arid habitats and are often found on rocks or in trees. Their diet consists of a variety of insects, lizards, and plant material.

Greater Short-Horned Lizard

Greater Short-horned Lizard

Greater short-horned lizards (Phrynosoma hernandesi) are of the spiny lizard family. They are found throughout much of the western US, including Utah, however they are rare in the park. They frequent a variety of habitats ranging from grasslands to high mountains. They feed primarily on ants, but also consume grasshoppers, beetles and other invertebrates. Close relatives of this lizard have unique defensive adaptations to ward off predators such as snakes, hawks, and coyotes. They can inflate their bodies to about twice the normal size and can shoot streams of blood out of their eyes, which is noxious to canines and may confuse predators.

Side-blotched Lizard

Side-blotched lizards (Uta stansburiana) are of the spiny lizard family. They are found throughout much of the western US, including Utah where they are abundant in the park. They are small grayish-brown lizards with dark blue to black patches behind their front legs. They inhabit areas of sandy or rocky soil containing scattered brush or trees and are primarily ground dwellers. Side-blothed lizards feed mainly on small invertebrates such as insects and scorpions, but adult males may cannibalize young lizards.

Other Spiny Lizards

The park is home to 6 species of Spiny Lizards, in the family Phrynosomatidae. Some of these lizards can be difficult to identify because they can range in appearance, have irregular patterning, and are often gray or brown. Breeding males are often easier to identify if able to view their brightly colored throats and necks.

Common sagebrush lizards (Sceloporus graciosus) are found throughout the western US and are abundant in the park. They are found in sagebrush habitats, but also occur in many other types of habitat, including pinyon-juniper forests and open forests. Their diet consists of invertebrates, primarily insects and spiders.

Plateau lizards (Sceloporus tristichus) are found in Colorado, Utah, and Arizona and are abundant in the park. They have long tails and pale stripes with a pattern of darker bars down either side of their backs. They are found in a variety of habitats including rocky areas of desert shrublands, sagebrush, grasslands, pinyon- juniper woodlands, and canyons. Plateau lizards forage on the ground but climb onto rocks, trees, fence posts, and wood piles to bask. They sit and wait for prey to wander within close proximity and feed on a variety of insects, spiders, snails, and small lizards.

Tree lizards (Urosaurus ornatus) are common in the park and range from southwestern Wyoming to central Mexico including eastern and southern Utah. These lizards are dark brown or black to light tan or gray. They are found in habitats ranging from deserts to the lower edges of the spruce-fir zone with areas along river and stream courses preferred. Their diet consists of insects and spiders.
