The eastern hog-nosed snake, often referred to as the “puff adder” from its dramatic behavior, is a common snake found in South Carolina. They are often mistaken for venomous snakes. The largest threat this snake will cause, is the injury you may receive if you trip while running away.

As a defense mechanism, the eastern hog-nosed snake will play dead, or roll over, defecating and releasing a foul smelling fluid from its anal gland. They will also flatten out their head and hiss loudly to detour a perceived threat. They can grow large, as we have found them up to 4′ ft in length. They are found throughout the entire State of South Carolina. Eastern hog-nosed snakes will strike if heavily agitated, so it is best to keep your distance.
