Non-venomous
Danger Level
Harmless; they lack a specialized bite mechanism and are generally too small to pierce human skin. They are not known to bite humans defensively.
Family
Order: Squamata; Suborder: Serpentes; Family: Colubridae; Subfamily: Dipsadinae; Genus: Carphophis; Species: Carphophis amoenus
Conservation
IUCN Red List: Least Concern. While common, they are sensitive to soil compaction and deforestation that removes the moist microhabitats they require.
Physical Description
Small, glass-smooth scales with a plain brown to reddish-brown dorsal color. The belly is a distinctively contrasting plain pink or salmon color. The head is small and flat, not distinct from the neck, with very small dark eyes. The tail ends in a sharp, spike-like scale.
Size & Dimensions
The specimen appears to be an adult of approximately 18-25 cm. Typical size range for the species is 19 to 28 cm (7.5 to 11 inches), with a maximum recorded length of 35 cm.
Habitat
Primarily fossorial, dwelling in deciduous forests with moist soil, leaf litter, and rotting logs. Prefers edge habitats and is often found on hillsides near water sources at low to moderate elevations.
Behavior & Temperament
Highly secretive and fossorial (burrowing). They are most active at night or during damp conditions but spend most time underground. When handled, they do not bite but will attempt to wedge their heads and sharp tail-tips against the handler's fingers in a harmless attempt to burrow.
Diet & Feeding
Specialized diet consisting almost exclusively of earthworms. They are active foragers within leaf litter and soft soil, using their pointed heads to navigate through the substrate.
Reproduction
Oviparous (egg-laying). Females lay clutches of 2 to 8 small, thin-shelled eggs in early summer, typically in rotting logs or underground cavities. Hatchlings emerge in late summer.
Venom Profile
Non-venomous - no medically significant venom.
Look-alikes
Often confused with the Smooth Earth Snake (Virginia valeriae), which has a more grayish tone and lack the pink belly, or the Sharp-tailed Snake (Contia tenuis), found in the western US. It is also superficially similar to large earthworms.
Conservation Status
IUCN Red List: Least Concern. While common, they are sensitive to soil compaction and deforestation that removes the moist microhabitats they require.
Cultural Significance
Ecologically significant as a predator of earthworms and a prey source for larger snakes and birds. They are often used as indicator species for healthy forest soil ecosystems.
Notable Features
Features a specialized keratinized scale on the tip of the tail which it uses to probe against predators or handlers, likely an adaptation to facilitate movement through compact soil or as a distraction tactic.
