Thornscrub Hook-Nosed Snake (Gyalopion quadrangulare)STATUS





Description: This foot-long snake is another smooth-scaled hog-nose look alike. Dorsum is white with wide black bars along the entire length. These extend down the sides where they are flecked with white. Sides are red between the black bars. Belly, white. The head is marked by a single dark bar. Upturned nose and color will identify this species.


Habitat: Its preferred habitat is deciduous and semi-deciduous forest, but it is also found in canyon bottoms, outwash plains, creosote bush desert, mesquite grassland foothills (including partly cultivated sections), thorn woodland, and dry tropical and subtropical forest. This snake burrows into loose soil.


Range: This species occurs in western and northwestern Mexico, extending marginally into the southwestern United States. Its range extends from extreme south-central Arizona (Pataginia-Pajarito Mountains area), southward through Sonora and Sinaloa to Nayarit, at elevations from near sea level to about 1,340 meters asl.


Found in these States: AZ


Diet: Primarily feeds on arthropods. Eats spiders, centipedes, and scorpions.


Reproduction: Oviparous. Habits of this egg-layer are unkown.


Status: Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
