The Southern hog-nosed snake is a harmless snake species native to the southeastern United States. It is small but stout with a wide neck and a sharply upturned snout. The dorsal color pattern consists of a light brown, yellowish, grayish, or reddish ground color, overlaid with a distinct row of dark blotches that alternate with smaller blotches on the flanks. The belly is distinctly darker in color than the underside of the tail in juveniles. As the snake ages, the underside usually becomes a pale white.
