Ficimia

Ficimia is a genus of colubrid snakes commonly known as hooknose snakes or hook-nosed snakes. There are seven species within the genus.

Geographic range

They are native primarily to Mexico, but they also range into the United States in the southern tip of Texas, and as far south as Guatemala, Belize and Honduras.

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 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.^[1]

Diet

Hook-nosed snakes feed primarily on spiders and centipedes.
