About Crotaphytus bicinctores

The Great Basin Collared Lizard

The Great Basin collared lizard, scientifically known as Crotaphytus bicinctores, is a reptile native to the arid landscapes of the Western United States. This species is also commonly referred to as the desert collared lizard or the Mojave black-collared lizard, reflecting its habitat and distinctive markings.

Description and Habitat

Physically, Crotaphytus bicinctores is similar in form and size to its relative, the common collared lizard (Crotaphytus collaris), but it is distinguished by its less flamboyant coloration. Males typically display hues ranging from brown to orange, often with touches of red or pink on their bellies, while females tend to be darker, appearing black or dark brown. A key characteristic is the presence of two prominent black bands encircling the neck, giving the species its name. The lizard possesses elongated scales near its claws and a tail that is more triangular in shape, contrasting with the rounder tail of C. collaris. Adults generally measure between 6.4 and 11.4 cm (2.5 to 4.5 inches) in snout-to-vent length, and they have a robust tail that can be up to twice the length of their body. Males are notable for having broader heads and more pronounced orange crossbands along their bodies compared to females.

Crotaphytus bicinctores is endemic to the Western United States, with its range encompassing California, most of Nevada, southeastern Oregon, southern Idaho, and the western parts of Utah and Arizona. Its preferred habitat consists of rocky desert environments, and it is particularly common in desert scrub and desert wash areas. The species is widely distributed across major desert regions, including the Mojave, Sonoran, and southeastern Great Basin deserts.

Diet and Behavior

The diet of the Great Basin collared lizard is primarily composed of arthropods. However, these lizards are opportunistic predators and will use their powerful jaws to capture and consume small vertebrates, such as other lizards, snakes, and rodents. Occasionally, they have also been observed to ingest plant matter.

Taxonomy

The Great Basin collared lizard belongs to the family Crotaphytidae. Its scientific classification highlights its distinctiveness within the broader group of lizards.
