Compare two species

Southern Hognose Snake vs. Eastern Hognose Snake

The two hognoses share the sandhills and sandy pinewoods of the Sandhills and southern coastal plain, and both flatten, hiss and play dead. A: Sharply upturned, almost a spade in the Southern Hognose Snake; upturned, but less sharply in the Eastern Hognose Snake. B: Grey, tan or reddish with three rows of square dark blotches; never plain black or grey in the Southern Hognose Snake; blotched, or plain black or grey in the Eastern Hognose Snake. Turn it over: the underside of the Southern Hognose's tail is the same colour as its belly; the Eastern's is paler than its belly.
