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 underside is usually white with dark flecking on the throat area. They are slender bodied, with a long tail.

Behavior

Like other species of whiptail lizard, the checkered whiptail is diurnal and insectivorous. They are wary, energetic, and fast moving, darting for cover if approached. They are found in semi-arid, rocky habitats, normally in canyon lands or hilled regions. They are parthenogenic, laying up to eight unfertilized eggs in mid summer, which hatch in six to eight weeks.

<span class="mw-page-title-main">Western whiptail</span> Species of lizard

The western whiptail 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 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 subspecific names – for example the California whiptail, Aspidoscelis tigris munda.

<span class="mw-page-title-main">Desert grassland whiptail lizard</span> Species of lizard

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 little striped whiptail is a species of lizard found in the southwestern United States and in northern Mexico. A significant amount of research was done on the species during the mid-1990s, with several new subspecies being added, many of which some sources consider to be distinct enough to warrant full species status, and the research is ongoing. It is called little to distinguish it from many other species known as striped whiptails and to indicate that it is the smallest of those species.
