About Sceloporus orcutti
Granite Spiny Lizard (Sceloporus orcutti)
The granite spiny lizard, scientifically known as Sceloporus orcutti, is a distinct species of lizard found in the arid landscapes of the southwestern United States and northwestern Mexico. Its common name derives from its preferred habitat and its spiny appearance, while in Mexican Spanish it is referred to as 'la espinosa del granito'. This species is a member of the Phrynosomatidae family and is recognized for its unique physical attributes and its association with rocky terrains.
Description and Habitat
Sceloporus orcutti typically measures between 7.6 to 10.8 centimeters in snout-to-vent length, with its total length, including the tail, reaching up to 28.9 centimeters. A defining characteristic of this lizard is its dorsal scales, which are strongly keeled and pointed across both the body and tail, giving it a textured appearance. Coloration varies significantly with age and sex. Adult males display scales with yellow-green and blue centers, complemented by deep blue patches on their chest and throat. In contrast, females and juveniles exhibit more subdued yellow-tan transverse bands along their body and tail. The species is strongly tied to its environment, being primarily observed perched on boulders within rocky hillsides and outcrops, where it can be seen from considerable distances.
Behavior and Reproduction
The granite spiny lizard is diurnal, actively foraging and basking during the day. Its behavior is closely linked to its rocky habitat, utilizing these features for thermoregulation and predator avoidance. Reproduction in Sceloporus orcutti is oviparous, meaning the females lay eggs. While detailed information on its diet, lifespan, and specific predators or threats is not extensively documented in all sources, its ecological niche within the desert and scrubland ecosystems of its native range is well-established.
