Western Hognose snakes are relatively small, stout-bodied snakes found throughout the Great Plains states of the U.S. from Canada to Mexico. Their color and pattern is highly variable from subspecies to subspecies, although most specimens appear much like the infamous rattlesnake to the untrained eye. This optical bluff, used in conjunction with a wide array of other clever defense tactics, makes these snakes quite unique among North American serpents.Although there is still debate whether Heterodon is mildly venomous or nonvenemous with toxic saliva, it is generally agreed that the species is indeed venomous. Regardless, the extremely rare bite from this rear-fanged snake is of no medical importance to humans. Symptoms range from negligible to localized slight swelling and itching. As with any animal though, care must be taken not to receive a bite as allergic reactions and infection are always a slight possibility.Males are considerably smaller than females, with adult lengths rarely exceeding 15-20 inches.These snakes get their common name from the modified rostral (nose) scales that are formed in an upturned manner, providing a very "hog-like" look. Additionally, this adaptation makes these snakes adept burrowers, which is a useful skill when hunting or seeking refuge from the elements.
