Ring-necked snakes are small, commonly encountered reptiles. These secretive snakes are widespread across various habitats, prompting questions about their venom status and potential risk to humans. This article clarifies facts about ring-necked snakes, including their venom and identification.
Understanding Ring-Necked Snake Venom
Ring-necked snakes, scientifically known as Diadophis punctatus, possess a mild venom that is not considered medically significant or dangerous to humans. They are rear-fanged snakes, meaning their small, grooved fangs are located at the back of their upper jaw. The venom, produced in a gland behind the eye, is primarily used to subdue their small prey, such as salamanders, earthworms, and slugs.
When a ring-necked snake bites, it typically needs to maneuver its prey far into its mouth to effectively deliver venom. Bites to humans are rare due to their docile nature and small mouth size. Even if a bite occurs, it is usually harmless, causing no systemic effects on humans.
Encountering a Ring-Necked Snake
If you encounter a ring-necked snake, observe it from a distance and allow it to move away naturally. These snakes are generally secretive and prefer to avoid confrontation, often trying to escape when disturbed. They are not aggressive and rarely attempt to bite humans, even when handled.
Should a bite occur, medical intervention is typically unnecessary due to their non-medically significant venom. Clean the affected area thoroughly with soap and water, similar to treating any minor scrape or cut, to prevent potential infection. The snake’s primary defense mechanisms involve releasing a foul-smelling musk or coiling their tail to display their brightly colored underside, rather than biting.
Identifying Ring-Necked Snakes
Ring-necked snakes have several distinct physical characteristics. They are small, slender snakes, typically 10 to 18 inches long as adults, though some subspecies can reach 28 inches. Their dorsal coloration is usually a solid shade of olive, brown, bluish-gray, or black.
The most recognizable feature is the prominent yellow, orange, or cream-colored ring around their neck, which gives them their common name. While this ring is typically complete, some populations may have incomplete rings or lack them entirely. The underside is often a vibrant yellow, orange, or red, sometimes marked with crescent-shaped black spots along the edges or a single row of black half-moons down the center. Their scales are smooth, distinguishing them from some other small, dark snake species.
