SADDLED LEAF-NOSED SNAKE
A small (up to 508 mm or 20"in total length) light gray, tan, or cream snake with fewer than 18 rounded, gray-brown blotches on the body.
A dark line extends across the top of the head and down through the eye to the upper lip. The snout is blunt and the head is barely distinct from the thick neck. The scale on the snout (rostral) is large, thick, triangular, and shield-like. The underside is plain pale gray or white. The scales are smooth and shiny and the pupils are elliptical. The similar Spotted Leaf-nosed Snake has more than 17 dorsal blotches.
This snake is found in south-central Arizona at elevations ranging from about 1,000' to ca. 3,000'.
The Saddled Leaf-nosed Snake is primarily an inhabitant of the Arizona Upland subdivision of the Sonoran Desertscrub community but it extends into the Lower Colorado River subdivision near Gila Bend and Florence. It is usually found above the flats in foothills and on moderate bajadas.
This nocturnal ground-dweller hibernates during the cold months of late fall and winter. It uses its enlarged rostral scale for burrowing and spends the majority of its time under the soil.
This dietary specialist feeds almost exclusively on the eggs of lizards and snakes. It might occasionally eat lizards.
A clutch of up to 6 eggs is laid in summer. Hatchlings begin to emerge in July.
