Description
Hooknose snakes are typically gray or olive green in color, with brown or black blotching down the back, and a cream-colored underside. They grow to a total length of 5–11 in (13–28 cm) and have a distinct upturned snout, which is similar to that of hognose snakes (genus Heterodon), and is used to aid in burrowing in loose, sandy soil. The dorsal scales are smooth (keeled in Heterodon), and the anal plate is divided.
Diet
Hook-nosed snakes feed primarily on spiders and centipedes.
