Venomous Status

Non-venomous (Aglyphous - lacks specialized fangs)

Danger Level

Harmless - low risk. They are not dangerous to humans, but can deliver a painful bite if provoked and are known for loud defensive hissing.

Family

Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Colubrinae, Genus: Pituophis, Species: P. catenifer, Subspecies: P. c. deserticola

Conservation

IUCN Status: Least Concern. Major threats include habitat loss and being mistaken for rattlesnakes and killed by humans.

Physical Description

Large, robust snake with a base color of tan or cream. Features a series of dark rectangular blotches along the back and smaller spots on the sides. Head is relatively narrow with a dark line between the eyes and from the eye to the corner of the mouth. This specimen displays keeled scales and a light-colored belly with dark spots.

Size & Dimensions

Specimen appears to be around 3-4 feet; species typical adult range is 3 to 6 feet (91-183 cm), with some reaching up to 8 feet.

Habitat

Found in a variety of habitats including grasslands, shrublands, open woodlands, and deserts. They range from sea level to high elevations up to 9,000 feet, often utilizing rodent burrows for shelter.

Behavior & Temperament

Diurnal in cooler months and crepuscular/nocturnal in hot summer months. Known for a loud defensive display: flattening the head, hissing loudly (using a specialized glottis), and vibrating the tail in dry vegetation to mimic a rattlesnake.

Diet & Feeding

Active forager that primarily eats small mammals (rodents, gophers), birds, eggs, and occasionally lizards. It kills prey through constriction.

Reproduction

Oviparous (egg-laying). Females lay clutches of 2 to 24 eggs in the summer, which hatch in late summer or early autumn.

Venom Profile

Non-venomous - no medically significant venom.

Look-alikes

Commonly confused with Western Rattlesnakes (Crotalus viridis/oreganus). Distinguishable by the lack of a rattle, presence of round pupils (vs. vertical), a narrower head, and no heat-sensing pits.

Conservation Status

IUCN Status: Least Concern. Major threats include habitat loss and being mistaken for rattlesnakes and killed by humans.

Cultural Significance

Highly beneficial to humans as natural pest control by regulating rodent populations in agricultural and suburban areas.

Notable Features

Possesses a specialized epiglottis that vibrates when the snake breathes out forcibly, producing an unusually loud, rasping hiss that enhances its mimicry of a rattlesnake.
