The Crotaphytidae, or collared lizards, are a family of desert-dwelling reptiles native to the Southwestern United States and northern Mexico. Alternatively they are recognized as a subfamily, Crotaphytinae. They are very fast-moving animals, with long limbs and tails, and are carnivorous, feeding mainly on insects and smaller lizards.
Lepidodactylus is a large genus of geckos, commonly known as scaly-toed geckos and closely related to house geckos or dtellas.
Crotaphytus is a genus of lizards commonly known as collared lizards. They are a genus of small to medium-sized predators indigenous to arid environments of the southwestern regions of North America.
The zebra-tailed lizard is a species of phrynosomatid lizard endemic to the Southwestern United States and northwestern Mexico.
Ophisaurus is a genus of superficially snake-like lizards in the family Anguidae, native to North America, North Africa and Southeast Asia. Although most species have no legs, their head shapes, movable eyelids, and external ear openings identify them as lizards. A few species have very small, stub-like legs near their rear vents. These are vestigial organs, meaning they once served an evolved purpose but are no longer used. They reach lengths of up to 1.2 metres (4 ft), but about two-thirds of this is the tail. Glass lizards feed on insects, spiders, other small reptiles, and young rodents. Their diets are limited by their inability to unhinge their jaws. Some glass lizards give birth to live young but most lay eggs.
The island night lizard is a species of night lizard native to three of the Channel Islands of California: San Nicolas Island, Santa Barbara Island, and San Clemente Island. A small number of island night lizards also live on Sutil Island, near Santa Barbara Island.
The common collared lizard, also commonly called eastern collared lizard, Oklahoma collared lizard, yellow-headed collared lizard, and collared lizard, is a North American species of lizard in the family Crotaphytidae. The common name "collared lizard" comes from the lizard's distinct coloration, which includes bands of black around the neck and shoulders that look like a collar. Males can be very colorful, with blue green bodies, yellow stripes on the tail and back, and yellow orange throats. There are five recognized subspecies.
Gambelia sila, commonly known as the blunt-nosed leopard lizard, is a species of lizard in the family Crotaphytidae. The species is endemic to southern California.
The Great Basin collared lizard, also known commonly as the desert collared lizard or the Mojave black-collared lizard, is a species of lizard in the family Crotaphytidae. The species is endemic to the Western United States. It is very similar to the common collared lizard, Crotaphytus collaris, in shape and size, but it lacks the bright extravagant colors. Males can be brown to orange and some red or pink on the belly. Females are more black or dark brown. C. bicintores has elongated scales near the claws and the tail is more triangular in shape than round as with C. collaris.
The desert grassland whiptail lizard is an all-female species of reptiles in North America. It was formerly placed in the genus Cnemidophorus. A common predator of the whiptail lizard is the leopard lizard, that prey on A. uniparens by using ambush and stalk haunting tactics. These reptiles reproduce by parthenogenesis. In this process, eggs undergo a chromosome doubling after meiosis, developing into lizards without being fertilized. However, ovulation is enhanced by female-female courtship and "mating" (pseudo-copulation) rituals that resemble the behavior of closely related species that reproduce sexually.
The Baja California leopard lizard is a species of lizard in the family Crotaphytidae. The species is endemic to Baja California and adjacent southern California.
The Baja California collared lizard or Baja black-collared lizard is a species of lizard in the family Crotaphytidae. The species is endemic to southern California and Baja California (Mexico).
The orange-throated whiptail is a species of lizard in the family Teiidae. The species was previously placed in the genus Cnemidophorus. Three subspecies are recognized as being valid, including the nominotypical subspecies.
Crotaphytus reticulatus, commonly called the reticulate collared lizard, is a species of moderately sized lizard in the family Crotaphytidae. The species is native to semiarid, rocky regions of the Tamaulipan mezquital. Its range includes the US state of Texas and the Mexican states of Coahuila, Nuevo León, and Tamaulipas. Of all the species in the family Crotaphytidae, C. reticulatus is the only species which is not restricted to rocky habitats.
The long-nosed leopard lizard is a species of relatively large North American lizard in the family Crotaphytidae. Gambelia wislizenii ranges in snout-to-vent length (SVL) from 8.3 to 14.6 cm. It has a large head, a long nose, and a long round tail that can be longer than its body. It is closely related to the blunt-nosed leopard lizard, which closely resembles the long-nosed leopard lizard in body proportions, but has a conspicuously blunt snout. The species G. wislizenii, once considered part of the genus Crotaphytus, is under moderate pressure because of habitat destruction but is categorized as "least concern".
Pristurus carteri, commonly known as Carter's rock gecko or Carter's semaphore gecko, is a species of gecko, a lizard in the family Sphaerodactylidae. The species is endemic to the Sinai Peninsula.
Grimser's collared lizard is a species of lizard in the family Iguanidae. The species is endemic to Baja California, Mexico.
The Madrean alligator lizard is a species of lizard in the family Anguidae. The species is endemic to the southwestern United States and adjacent northwestern Mexico.
