Diadophis punctatus

Description

Diadophis punctatus, commonly known as the ring-necked snake or ringneck snake, is a harmless species of colubrid snake found throughout much of the United States, central Mexico, and southeastern Canada. Ring-necked snakes are secretive, nocturnal snakes, so are rarely seen during the day time. They are slightly venomous, but their nonaggressive nature and small, rear-facing fangs pose little threat to humans who wish to handle them. They are best known for their unique defense posture of curling up their tails, exposing their bright red-orange posterior, ventral surface when threatened.
