Ficimia is a genus of colubrid snakes commonly known as hooknose snakes or hook-nosed snakes, which are endemic to North America. There are seven species within the genus.
Species of Ficimia are found in Mexico, in the United States in the southern tip of Texas, and as far south as Guatemala, Belize, and Honduras.
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. [2]
Hook-nosed snakes feed primarily on spiders and centipedes.
The following seven species are recognized as being valid. [3]
Macrovipera lebetinus, known as the blunt-nosed viper, Lebetine viper, Levant viper, and by other common names, is a viper species found in North Africa, much of the Middle East, and as far east as Kashmir. Like all other vipers, it is venomous. Five subspecies are currently recognized, including the nominate race described here.
Gerarda prevostiana, commonly known as the cat-eyed water snake, Gerard's water snake, and the glossy marsh snake, is a species of snake in the family Homalopsidae. The species is endemic to Asia. It is the only species in the genus Gerarda.

Heterodon is a genus of harmless colubrid snakes endemic to North America. They are stout with upturned snouts and are perhaps best known for their characteristic threat displays. Three species are currently recognized. Members of the genus are commonly known as hognose snakes, hog-nosed snakes, North American hog-nosed snakes, and colloquially puff adders.
The eastern hog-nosed snake, is a species of mildly venomous rear-fanged snake in the family Colubridae. The species is endemic to North America. There are no subspecies that are recognized as being valid. This species prefers habitats with sandy soils and a combination of grass fields and forest edges. They come in many different colorations and have the identifiable upturned "snout". They can be found in captivity but are a more difficult species to keep due to a specialized diet of toads.
