What does a Poisonous (Venomous) Snake Look Like?
Venomous snakes have distinct heads that set them apart from non-venomous snakes. Non-venomous snakes have a rounded head, while venomous snakes have a more triangular-shaped head. The shape of a venomous snake’s head may deter predators. However, some non-venomous snakes can mimic the triangular shape of non-venomous snakes by flattening their heads. For example, the Copperhead, which is a common venomous snake found in Virginia has a very beautiful camouflage pattern, along with elliptical pupils and a distinctive pit organ between the eye and nose. Beware when hiking in the fall, these snakes are well-camouflaged among brown and gold leaves!
