Habitat
This species primarily inhabits arid deserts and semi-desert regions, including sandy dunes, rocky outcrops, and gravel plains. It is found across North Africa, from Morocco to Egypt, and into the Middle East as far as Iran. They prefer areas with loose sand for burrowing and hunting.
Diet
The Desert horned viper feeds mainly on small rodents like jerboas and gerbils, as well as lizards and occasionally birds. It is an ambush predator that lies buried in the sand, striking quickly when prey approaches, and hunts primarily at night or during cooler parts of the day.
Behavior
Desert horned vipers are primarily nocturnal, emerging at night to hunt and avoid the extreme daytime heat, using sidewinding locomotion to move efficiently across sand. They are solitary and territorial, often burrowing into the sand during the day for protection and ambush hunting. When threatened, they may hiss and strike, but they generally avoid confrontation.
Conservation Status
The IUCN status of the Desert horned viper is Least Concern, with a stable population trend across its wide range. Major threats include habitat destruction from human expansion and off-road vehicles, as well as incidental killing by people.
