Conservation
Least Concern according to the IUCN Red List, with widespread distribution and stable populations, though locally impacted by habitat loss and road mortality.
Physical Description
The specimen displays a distinct pattern of dark blotches (black, dark brown, or gray) along the back interspersed with lighter reddish or yellowish-white interspaces, often with checkered or speckled sides. The head is slightly distinct from the neck with a pointed snout typical of burrowing snakes.
Size & Dimensions
The pictured specimen appears to be approximately 60-90 cm. Typical adult size ranges from 51 to 108 cm in total length.
Habitat
Found in arid and semi-arid regions including deserts, shrublands, grasslands, and chaparral. They prefer sandy or gravelly soils where they can easily burrow.
Diet & Feeding
Primarily feeds on lizards, lizard eggs, small snakes, and occasionally small rodents. They are active foragers that search for prey in rodent burrows and under rocks.
Reproduction
Oviparous species. Females typically lay clutches of 4 to 9 eggs in underground nests during the summer months.
Look-alikes
Often confused with various king snakes (Lampropeltis species) and patch-nosed snakes (Salvadora species). Distinguished by an undivided anal plate in some related groups, but specifically by snout shape and specific red/black saddle patterns.
Conservation Status
Least Concern according to the IUCN Red List, with widespread distribution and stable populations, though locally impacted by habitat loss and road mortality.
Cultural Significance
Plays an important role in arid ecosystems by helping control populations of rodents and lizards.
Notable Features
Features a specialized uptrodden or pointed rostral scale adapted for pushing through loose sand and soil during burrowing.
