Description
A small (11 - 17 inch) snake with alternating bands of orange and tan on cream or tan on cream. Less commonly specimens have been documented as having black bands on white. The snout is usually cream to light yellow and has a noticeable point to assist in digging. The small black eyes are covered by a black mask. The western shovel-nosed snake is distinguished from the similar looking coral snake, by the yellow snout and lack of full banding around the belly. A similar species, the Sonoran Shovel-nosed Snake has less than 20 bands on its body.
Geographic Range
The snake is found in the United States (Arizona, California, Nevada) and Mexico.[3] The snake is primarily found in Sonoran Desert scrub or Mojave Desert scrub.[4]
Diet
The western shovel-nosed snake feeds on a variety of invertebrates including insects, spiders, centipedes, and scorpions. They have been documented eating the eggs of other reptiles.[5]
