California Night Snake (Hypsiglena ochrorhynchus nuchalata)STATUS





Description: The California night snake grows to a total length of 12 to 26 inches, with hatchlings about 7 inches in total length. The snake has a narrow flat head, smooth dorsal scales in 19 rows, and eyes with vertically elliptical pupils. They are rear-fanged and considered to be venomous, but not dangerous to humans. Its color may be light gray, light brown, tan, or cream, often matching the substrate of the region, with dark brown or dark grey blotches down the back and sides. The underside is whitish or yellowish and unmarked, and they usually have a pair of large dark markings on the neck, and a dark bar through or behind the eyes.


Habitat: They prefer semiarid habitats with rocky soils.


Range: The Coast night snake ranges throughout western California, ringing the central valley, but is not found in the valley itself. It is one of two night snake species in the state. The other is the desert night snake, Hypsiglena chlorophaea.


Found in these States: CA


Diet: Their diet consists of primarily lizards, but they will also eat smaller snakes, and occasionally the soft bodied insect.


Reproduction: They are an oviparous subspecies that breeds from April to September.


Status: Listed as Least Concern in view of the wide distribution, large number of locations, presumed large population, and because the population is unlikely to be declining fast enough to qualify for listing in a more threatened category.
