What environmental conditions are characteristic of the regions where the Western diamondback rattlesnake maintains a significant presence?
Answer
Arid and semi-arid regions of the southwestern United States and northern Mexico
The *Crotalus atrox* is highly specialized for survival in harsh, dry environments. Its successful distribution is strongly anchored in the characteristic landscapes of the southwestern United States, including states like Texas and Arizona, extending into northern Mexico. These environments are typically classified as arid or semi-arid, featuring ecosystems such as desert scrub, chaparral, and rocky hillsides. The snake's coloration and physiological adaptations are finely tuned to thrive in these high-temperature, resource-scarce settings.
