Description

Not Dangerous - This snake does not have venom that can cause death or serious illness or injury in most humans.

Commonly described as "harmless" or "not poisonous" to indicate that its bite is not dangerous, but "not venomous" is more accurate. (A poisonous snake can hurt you if you eat it. A venomous snake can hurt you if it bites you.)

Length

Adults are 26-70 inches in length (66-178 cm). (Stebbins, 2003) Average length is 3 - 4 feet.

Appearance

A medium-sized muscular snake with smooth, glossy scales, a faded or bleached-out appearance, and a short tail.
Rostral scale (on the nose) is enlarged for digging (but not as much so as that of a patch-nosed snake or a leaf-nosed snake.)
Pupils are rounded.

Color and Pattern

Generally darker than other California Glossy snake subspecies - a tan or light brown ground color with dark brown blotches with dark edges on the back and sides and a pale, unmarked underside.
Dark line behind each eye and a dark line (a "unibrow") between the eyes.

An average of 63 narrow blotches on body.

Similar Snakes

Comparison of the 3 subspecies of Arizona elegans in California, along with sympatric species similar in appearance - Pituophis catenifer - Gopher Snake,
Trimorphodon biscutatus - Lyre Snake,
Hypsiglena - Night Snakes,
Coluber constrictor mormon - Western Yellow-Bellied Racer (juvenile).

Life History and Behavior

Activity

Nocturnal.
Hides underground in daytime under rocks, in exsisting burrows, or uses its specialized nose to make its own burrow.
Typically active from late February until November, depending on the weather. Most active in May. Less active during Summer.

Diet and Feeding

Preys mostly on sleeping diurnal lizards, but also eats small snakes, terrestrial birds, and nocturnally-active mammals.
Hunts active mammals at night by waiting in ambush.
Kills prey by direct swallowing or constriction.

Reproduction

Females are oviparous - laying from 3 - 23 eggs (more often 5-12) in June and July. (Stebbins, 2003)
Eggs most likely hatch in late summer and early fall. (Probably late September and October.)

Habitat

Inhabits arid scrub, rocky washes, grasslands, chaparral.
Appears to prefer microhabitats of open areas and areas with soil loose enough for easy burrowing.

Geographical Range

This subspecies, Arizona elegans occidentalis - California Glossy Snake, occurs from the eastern part of the San Francisco Bay Area south to northwestern Baja California. It is absent along the central coast. There are also old reports of this snake from the Santa Monica Mountains.

In July 2023, Benjamin German found a dor in Monterey County (shown above) which might be the first county record for the species.

The species Arizona elegans - Western Glossy Snake, has a very wide range, occurring through most of the southwest, and the southeastern part of the Midwest, and south into Mexico, including northern Baja California.

Elevational Range

The species is found from below sea level to around 7,218 ft. (2,200 m). (Stebbins, 2003)

Notes on Taxonomy

Collins elevated the western Glossy Snakes - A. e. occidentalis, A. e. eburnata, and A. e. candida - to specific status (Arizona occidentalis) (1991, Herp. Review 22:42-43) with the eastern Glossy Snakes remaining Arizona elegans, but this change has not been widely accepted.

Conservation Issues (Conservation Status)

Designated a California Species of Special Concern

"The greatest threat to this subspecies is habitat modification due to agricultural, commercial, and residential development. However, the specific mechanisms that cause declines are not well understood."
(Robert C. Thomson, Amber N. Wright, and H. Bradley Shaffer. California Amphibian and Reptile Species of Special Concern. University of California Press, 2016.)

Protected from take with a sport fishing license beginning in 2013 by a special closure:
"No glossy snakes (Arizona elegans) may be taken in the following counties: Alameda, Fresno, Imperial (west of Hwy 111), Kern, Los Angeles, Riverside (southwest of Hwy 111 and I-10), San Benito, San Bernardino (West of I-215 and Hwy 138), San Diego, San Joaquin, San Luis Obispo, Santa Barbara, Santa Clara and Tulare."

Conservation Status
The following conservation status listings for this animal are taken from the April 2024 State of California Special Animals List and the April 2024 Federally Listed Endangered and Threatened Animals of California list (unless indicated otherwise below.) Both lists are produced by multiple agencies every year, and sometimes more than once per year, so the conservation status listing information found below might not be from the most recent lists. To make sure you are seeing the most recent listings, go to this California Department of Fish and Wildlife web page where you can search for and download both lists: https://www.wildlife.ca.gov/Data/CNDDB/Plants-and-Animals. A detailed explanation of the meaning of the status listing symbols can be found at the beginning of the two lists. For quick reference, I have included them on my Special Status Information page. If no status is listed here, the animal is not included on either list. This most likely indicates that there are no serious conservation concerns for the animal. To find out more about an animal's status you can also go to the NatureServe and IUCN websites to check their rankings. Check the current California Department of Fish and Wildlife sport fishing regulations to find out if this animal can be legally pursued and handled or collected with possession of a current fishing license. You can also look at the summary of the sport fishing regulations as they apply only to reptiles and amphibians that has been made for this website. Protected from take with a sport fishing license beginning in 2013 by a special closure in counties where the subspecies would be found: No glossy snakes (Arizona elegans) may be taken in the following counties: Alameda, Fresno, Imperial (west of Hwy 111), Kern, Los Angeles, Riverside (southwest of Hwy 111 and I-10), San Benito, San Bernardino (West of I-215 and Hwy 138), San Diego, San Joaquin, San Luis Obispo, Santa Barbara, Santa Clara and Tulare.
