Colorado In United States
Colorado (, other variants) is a state in the Mountain states, Mountain West subregion of the Western United States. It encompasses most of the Southern Rocky Mountains, as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is the List of U.S. states and territories by area, eighth most extensive and List of U.S. states and territories by population, 21st most populous U.S. state. The 2020 United States Census, 2020 United States census enumerated the population of Colorado at 5,773,714, an increase of 14.80% since the 2010 United States Census, 2010 United States census. The region has been inhabited by Indigenous peoples of the Americas, Native Americans and their Paleo-Indians, ancestors for at least 13,500 years and possibly much longer. The eastern edge of the Rocky Mountains was a major migration route for early peoples who spread throughout the Americas. "''Colorado''" is the Spanish adjective meaning "ruddy", th ...

Urosaurus Ornatus
''Urosaurus ornatus'', commonly known as the ornate tree lizard, is a species of lizard in the family Phrynosomatidae. The species is native to the southwestern United States and northwestern Mexico. The species, which was formerly called simply the "tree lizard", has been used to study physiological changes during the fight-or-flight response as related to stress and aggressive competition. Its life history and costs of reproduction have been documented in field populations in New Mexico and Arizona. This species has been fairly well studied because of its interesting variation in throat color in males (within a population) that can correlate with different reproductive strategies,Hews DK, Thompson CW, Moore IT, Moore MC (1997). "Population frequencies of alternative male phenotypes in tree lizards: geographic variation and common-garden rearing studies". ''Behavioral Ecology and Sociobiology'' 41: 371-380.

Coluber Constrictor
The eastern racer (''Coluber constrictor'') is a species of nonvenomous snake in the family Colubridae. The species is endemic to North America and Central America. Eleven subspecies, including the nominotypical subspecies, are recognized, which as a group are commonly referred to as the eastern racers. The species is monotypic in the genus ''Coluber''. Geographic range ''C. constrictor'' is found throughout the United States, east of the Rocky Mountains, but it also ranges north into Canada and south into Mexico, Guatemala, and Belize.

Glossy Snake
''Arizona elegans'' is a species of medium-sized colubrid snake commonly referred to as the glossy snake or the faded snake, which is endemic to the southwestern United States and Mexico. It has several subspecies. Some have recommended that ''A. elegans occidentalis'' be granted full species status. Subspecies Subspecies of ''Arizona elegans'' include: * '' Arizona elegans arenicola'' Dixon, 1960 – Texas glossy snake * ''Arizona elegans candida'' Klauber, 1946 – Western Mojave glossy snake * '' Arizona elegans eburnata'' Klauber, 1946 – Desert glossy snake * '' Arizona elegans elegans'' Kennicott, 1859 – Kansas glossy snake * '' Arizona elegans expolita'' Klauber, 1946 – Chihuahua glossy snake * '' Arizona elegans noctivaga'' Klauber, 1946 – Arizona glossy snake * '' Arizona elegans occidentalis'' Blanchard, 1924 – California glossy snake * '' Arizona elegans philipi'' Klauber, 1946 – Painted Desert glossy snake Description The glossy snake and its many sub ...

Pantherophis Emoryi
''Pantherophis emoryi'', commonly known as the Great Plains rat snake, is a species of nonvenomous rat snake in the family Colubridae. The species is native to the central part of the United States, from Missouri to Nebraska, to Colorado, south to Texas, and into northern Mexico. Etymology The epithet, ''emoryi'', is in honor of Brigadier General William Hemsley Emory, who was chief surveyor of the U.S. Boundary Survey team of 1852 and collected specimens for the Smithsonian Institution. As such, it is sometimes referred to as Emory's rat snake. Common names Additional common names for ''Pantherophis emoryi'' include the following: brown rat snake, chicken snake, eastern spotted snake, Emory's Coluber, Emory's pilot snake, Emory's racer, Emory's snake, gray rat snake, mouse snake, prairie rat snake, spotted mouse snake, Texas rat snake, and western pilot snake.

Colubridae
Colubridae (, commonly known as colubrids , from la, coluber, 'snake') is a family of snakes. With 249 genera, it is the largest snake family. The earliest species of the family date back to the Oligocene epoch. Colubrid snakes are found on every continent except Antarctica. Description While most colubrids are not venomous (or have venom that is not known to be harmful to humans) and are mostly harmless, a few groups, such as genus ''Boiga'', can produce medically significant injuries. In addition, the boomslang, the twig snakes, and the Asian genus ''Rhabdophis'' have caused human fatalities. Some colubrids are described as opisthoglyphous (often called "rear-fanged"), meaning they have elongated, grooved teeth located in the back of their upper jaws. It is likely that opisthoglyphous dentition evolved many times in the history of snakes and is an evolutionary precursor to the fangs of vipers and elapids, which are located in the front of the mouth.

Western Whiptail
The western whiptail (''Aspidoscelis tigris'') is a species of lizard in the family Teiidae. The species ranges throughout most of the southwestern United States and northern Mexico. Most of its populations appear stable, and it is not listed as endangered in any of the states comprising its range. It lives in a wide variety of habitats, including deserts and semiarid shrubland, usually in areas with sparse vegetation; it also may be found in woodland, open dry forest, and riparian growth. It lives in burrows. Major differences between this species and the checkered whiptail (''Aspidoscelis tesselatus'') include the lack of enlarged scales anterior to the gular fold and the presence of enlarged postantebrachial scales. It was previously known as ''Cnemidophorus tigris'', until phylogenetic analyses concluded that the genus ''Cnemidophorus'' was polyphyletic. Since it does not migrate, a number of forms have developed in different regions, several of which have been given subspec ...

Common Checkered Whiptail
The checkered whiptail (''Aspidoscelis tesselata'') is a species of lizard found in the southwestern United States in Colorado, Texas and New Mexico, and in northern Mexico in Chihuahua and Coahuila. Many sources believe that the species originated from the hybridization of the marbled whiptail, '' Aspidoscelis marmorata'', the plateau spotted whiptail, '' Aspidoscelis septemvittata'', and possibly the six-lined racerunner, '' Aspidoscelis sexlineata''. It is one of many lizard species known to be parthenogenic. It is sometimes referred to as the common checkered whiptail to differentiate it from several other species known as checkered whiptails. Description The checkered whiptail grows to a body length (head to back legs) of about 4 inches, with a tail length of 5-6 inches. Their pattern and base coloration varies widely, with brown or black blotching, checkering or striping on a pale yellow or white base color. Their rear legs often have dark spotting, and their undersi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Six-lined Racerunner
The six-lined racerunner (''Aspidoscelis sexlineatus'') is a species of lizard native to the United States and Mexico. Geographic range The six-lined racerunner is found throughout much of the southeastern and south-central portion of the United States, from Maryland to Florida in the east, across the Great Plains to southern Texas and northern Mexico. sexlineatus)] In a study conducted on A. sexlineata in Mexico, the majority of the individuals found were inhabiting areas near the seashore that were formed and influenced from maritime climate and hurricanes. The species' range also reaches north to Wisconsin and Minnesota. A small disjunct population is found in Tuscola County, Michigan. Description The six-lined racerunner is typically dark green, brown, or black in color, with six yellow or green-yellow stripes that extend down the body from head to tail. The underside is usually white in color on females, and a pale blue in males. Males also sometimes have a pale green-color ...

Aspidoscelis
''Aspidoscelis'' is a genus of whiptail lizards in the family Teiidae. Taxonomy The nomenclature for the genus ''Aspidoscelis'' was published by T.W. Reeder et al. in 2002. Many species that were formerly included in the genus '' Cnemidophorus'' are now considered ''Aspidoscelis'' based upon divergent characters between the two groups. Etymology The name ''Aspidoscelis'' literally means "shield-leg", from the Ancient Greek ' ("shield") and ' ("leg"). Species The following species are recognized as being valid. *''Aspidoscelis angusticeps'' - Yucatán whiptail *''Aspidoscelis arizonae'' - Arizona striped whiptail *''Aspidoscelis burti'' - canyon spotted whiptail *''Aspidoscelis calidipes'' - Tepalcatepec Valley whiptail *''Aspidoscelis carmenensis'' - Carmen Island whiptail *''Aspidoscelis ceralbensis'' - Cerralvo Island whiptail *''Aspidoscelis communis'' - Colima giant whiptail *''Aspidoscelis costatus'' - Mexico whiptail lizard *''Aspidoscelis cozumela'' - Cozumel ra ...

Teiidae
Teiidae is a family of autarchoglossan lizards native to the Americas. Members of this family are generally known as whiptails or racerunners; however, tegus also belong to this family. Teiidae is sister to the Gymnopthalmidae, and both families comprise the Teiioidea. The Teiidae includes several parthenogenic species – a mode of clonal reproduction. Presently, the Teiidae consists of approximately 150 species in eighteen genera. Morphology and behavior Teiids can be distinguished from other lizards by the following characteristics: they have large rectangular scales that form distinct transverse rows ventrally and generally small granular scales dorsally, they have head scales that are separate from the skull bones, and the teiid teeth are solid at the base and "glued" to the jaw bones. Additionally, all teiids have a forked, snake-like tongue. They all possess well-developed limbs. Teiids are all terrestrial (few are semi-aquatic) and diurnal, and are primarily carnivor ...

Plestiodon Multivirgatus
''Plestiodon multivirgatus'', commonly known as the many-lined skink, the northern many-lined skink, or the variable skink, is a medium-sized species of lizard, a member of the North American skink genus ''Plestiodon'' in the family Scincidae. The species is native to the western United States. Taxonomy The taxonomy of this species is somewhat unclear, even amongst researchers. Most commonly, two subspecies are recognized: *''P. m. multivirgatus'' ( Hallowell, 1857) – northern many-lined skink *''P. m. epipleurotus'' (Cope, 1880) – variable skink The latter is sometimes treated as a separate species ''Plestiodon epipleurotus'' or ''Plestiodon gaigeae'' (Taylor, 1935), or given as the subspecies ''P. m. gaigeae''. These last two scientific names are in honor of American herpetologist Helen Beulah Thompson Gaige (1890–1976) of the University of Michigan. Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).
